Jeep Temperature: Thermostat or Sensor Issue
HTML-код
- Опубликовано: 3 авг 2024
- Here I cover some tips to help identify if your thermostat is opening and closing properly. It's as easy as watching your hoses and feeling them as your car engine warms up. I also show where the Jeep Wrangler 4.0 temperature sending unit is located and discuss the coolant thermostat.
Temperature Sending Switch amzn.to/2F6Msjv
(located towards back of engine on driver side)
Sends signal to temperature gauge in cab.
Thermostat housing sensor amzn.to/2FM6jl7
(located on the thermostat housing. Coolant temperature)
A few of my favorite tools:
Dewalt 1/4 impact driver
amzn.to/2GYEJ4w
Be sure to get the kit with 2 batteries. You'll be glad you did!
Craftsman 165 Mechanics Tool Set

"I have a little leak ill fix later" Sounds like me do great job on other people's cars but have my cars on the waiting list. Lol
Couldn’t help but subscribe.
Love the fact you daily a ‘94 that isn’t pristine, and you go through fixing all the problems in detail as they occur.
The craftsman tools and nothing super fancy, just fixing the Jeep!

Sold my YJ a few months ago , this video reminds me of how simple Jeeps used to be. Great video as usual!
"used to be" is right! I cut my teeth on a 77 CJ7... They went to YJ, then TJ, now JK. 8 total in close to 30 years. If I ever own another Jeep, it will likely be another YJ!
Great sharing your video tutorials. It was so helpful. Sending my support
Great video ! Saved me some cash and taught me how to do some of my own work as I never had tools or garage till now so Thanks man
Thank you for providing such a great informational video. Really glad I ran into your page. Learn some good tricks from you on this one!
I live on a tropical region, therefore I installed a 160 degree thermostat along with a new water pump, radiator and auxiliary transmission fluid cooler. I run the stock fan setup and also have a 3 year old fan clutch. It runs at 210 on the dashboard but sometimes it runs a little hot. I changed the sending unit 2 times and no change. I installed a separate temp gauge and placed the sensor on the radiator drain plug hole. And it stays at 180 and max out at 200
Much appreciated for the clarification definitely helps it's just thinking about that to tell the difference and to pinpoint the problem and to help pinpoint the problem
Said "So ...."38 times🤣 this is great I took a wrong turn and dont feel stable with your camera jitters but you are a good dude this video will help some people👍🇺🇲
This was exactly the information I was looking for ( temperature sending unit )....thanx
Great info on the "heater" trick. If the heat coming out of your vents in the cab isn't HOT after the engine has been operating for awhile, check the thermostat and radiator hoses for temperature differences. If they are about the same, most likely the thermostat is stuck OPEN. This is the first thing I ask customers, "Does the heat coming out of your vents seem warm or hot?"
Also forgot to mention the tid-bit about the radiator fan. If the engine is up at operating temperature and the thermostat opens but the temperature isn't decreasing, the computer will have the radiator fan operate. If the fan doesn't work, then that's another path to troubleshoot.
Two different options here if the thermostat is GOOD so you are looking at the radiator fan now:
1) If the engine is running cold, verify the fan isn't ON constantly.
2) If the engine is running hot, verify the fan does turn ON when commanded. Most of the time, you can use a scan tool to operate the fan electronically. If you don't have a tool, pull the plug for the fan (not sure how to do it on an older vehicle with a fan clutch) and apply 12VDC to the pins/sockets. The fan doesn't always run at FULL speed, so 9 to 12 volts is a good test to verify the fan operating speeds (less voltage means lower fan speed, higher voltage means higher fan speed). I use a 9V battery for a lower voltage test. If the voltage test works and the fan is operational, then work back to the sending unit, coolant temp sensor, or the relay/control module to verify that it's putting out the correct voltage when needed, or operating at all.
You can get into the weeds on this error, but time put forth up front will save you money and time later on if the problem isn't diagnosed properly the first time. You hit all of the other key points.
My BMW 2004 model....has been running cold...last night ..in a split second it went to the H.... however....the car didn't overheat....is that a false reading? I checked the cylinder heads..and oil....it didn't look frothy.. etc...so I didn't blow a head gasket. I was told it is either the thermostat or the coolant temperature sensor...any advice?
@@williambernstein4313 if it spikes randomly, most likely wiring to the sensor. Wiggle the wiring and have someone else watch the gauge. If it doesn't fluctuate, possible sensor. Worst case, your ECM is going nuts. Hate BMW/Mercedes for their wiring and computer issues. Thermostats don't react in the blink of an eye, so I would put that further down on the troubleshooting list.
Appreciate your videos. I have a 95 yj, 4cl, 210k kms. Runs well, no leaks, but the temp gauge fluctuates a bit when up to operating temp, briefly showing a little hotter while driving, though most dead centre on the gauge while driving, and always dead centre when idling in traffic. When I turn the engine off but leave the key in acc, the gauge often runs up another 10 degrees C or so, to the next line on the gauge, but not to the warning line. It settles to the middle line as soon as I start it back up. Heat works great. Original rad, no visible leaks and I keep an eye on the coolant level both in the rad and reservoir, but I do faintly smell coolant sometimes when close to the rad after driving. Newer rad cap, new heater core and rad hoses this winter. I rebled the system thinking might be air. Haven't changed the t-stat though. Suggestions?
Hi my car was overheating i fix cylinder head but still is overheating i changed themostat but still overheating can somehelp me
Good information....! You are the best troubleshooter...!
An excellent contribution - 'on point'. Goes to show that you can teach an 'old dog' new tricks - like the heater hose warming before the radiator hose to verify the status of the thermostat! Thank you. Lloyd, Queensland, Australia
I overheated yesterday. This will help a great deal. Thanks man. I love my in line six. That thing loves to climb hills!
Awesome. Thank you!
@@JeepSolid now I'm trying to figure out how to drain the fluid without making a mess. I'm looking for a plug.
@@JeepSolid my cherokee has a sealed radiator. There's no cap.
May have to remove bottom hose.
@@JeepSolid I changed the thermostat and the coolant reservoir. When I hooked the three hoses back up I may have crossed the heater hoses. Is that gonna hurt anything? The reservoir did fill to the top when I started the motor. My friends are telling me it's okay. Dude, is it really okay? ...lol... I gotta know. 😜
I have a 1992 Jeep YJ with a 2.5 engine. I have only one sensor. My gauge is not working but other gauges are working in the cluster. When I bought the Jeep someone had put an after market temp gauge in. Changed the sensor at the thermostat housing. It worked. I found the old sensor still plugged into the wiring plug harness. I put a new sensor in the where the aftermarket was and plugged the original plug back in. The original gauge still didn't work. Also the aftermarket didn't work. I suspect the original wiring may be cut some place under the dash. As mentioned other gauges are working in the cluster. Thoughts. Your videos are good and enjoy them. I just want the original to work. Thank you. P.S. I do not have another sensor at the back of the engine any where arrond the head. I have looked and felt many times. Is this a 4.0 addition?
My little diagnostic test for the thermostat off a cold start is to watch the temperature gauge as the engine warms up. When it hits the thermostat opening temp (195° for my YJ) the temperature on the gauge will suddenly drop when the cold radiator starts circulating.
I personally have never ever had one stick open but your explanation on how to tell if it stuck open is correct.
I have run plenty of engines with no thermostat in a pinch and the exact behavior you described as stuck open occurs.
In a pinch on the road if your thermostat does fail stuck closed, you can remove it. I did that once and salvaged the torn gasket and used my wives finger nail polish for gasket sealer!
Good tips. I love how you used your wife's fingernail polish for the repair. I've actually used my kids fingernail polish in some videos for drive line alignment. Haha!
Maybe we need to throw a bottle in our glove box!
helpful video Here's an odd question. I get okay heat. I have 2000 jeep tj... new rad, no leaks and have noticed when I drive long distances or faster for long periods I loose the heat I had before . My heater core might be backed up but sometimes I get good heat for a bit and then I dont. I have pump by hand the heater hoses and sometimes I get the heat back again for a bit. I'm thinking I should do it myself Tempeture gauge switch ????
I have a gmc envoy, mi heater and cooling system stopped working.
What should I check first?, thanks
Do you guys know if the temperature sending units are the same for celsius and fahrenheit gauges?
Thank you to show how simple is to chance a termostat
Thanks for the video. Do you know if there are two temperature sensors on 2016 rubicon? Replaced the one on driver side down on the bottom of the block. I don’t see a second one. Wish I had seen video prior to doing work regarding the flow of water when thermostat opens after warming. May have avoided changing that. Oh well over a 100k probably needed it anyway 😂
Such a helpful video my man.
Cool! Thx
happy new year - great video ! My Crown 195 Tstat opens up and closes properly - however the water temp remains at ab. 185 which is too cold. Your thoughts ? Thanks !
The lower hose on my 1995 yj 2.5 is not warming up at all. Gauge is reading around 120 degrees too after a radiator replacement, tstat and gasket and new fluid. Any suggestions? Love your videos!
I just replaced my thermostat and temp sensor and the temperature gauge is still not moving. Is it time to change the temp gauge itself at this point?
but this video was super helpful. Few days ago I found out it was the Sensor towards the rear of the block. I have the 2.5L and I dont haver the sensor thar goes to the actual thermostat
Ah, video was a day late for ya. Glad you got it figured out.
By chance can the temp sensor that goes into the thermostat housing be turned into the sending sensor?
can i just say that it made my day when you actually told everyone who asked the question. LOL
Haha!! Awesome. Thanks for the question.
What if you bypassed your heater core ? 2001 grand Cherokee Laredo
Love your channel!!! Can you do a video on replacing motor mounts? I have a 95 yj. I did the drivers side, but the passenger side looks a little intimidating!!
I'll be removing the motor on my project 92 yj soon. That may help
Tim Chancellor ruclips.net/video/9ncVtw73tv8/видео.html
Kindly may you do the same for Jeep grand Cherokee 2001 v8
They’re easy. Get a service jack and a wood block. Jack and support the engine by the oil pan drain bolt side.
Hey there, my 04 WJ with the 4.0 slightly runs up to around 210 if im in traffic or after high load... replaced thermostat, but am now thinking the fan is not switching on when instructed to. What sensor should I replace in an attempt to get the fan moving when it hits 208?
Hello, I have an 08 wrangler and it always runs 217-230 could my ect sensor be going bad?
I have 1992 Jeep Cherokee XJ with all stock parts in it. My problem is my Jeep takes awhile to heat up and does NOT hold the heat in the cab very when it’s not running or driving down the freeway. It used to get pretty toasty before the large metal fuse on the back on my van speed control fried up. We thought it was my fan blowing motor cause that died when the fuse controller died so we replaced my fan blower (which needed replacing anyways due to a loud motor) and then we pulled my dash off and looked behind the control unit and found the fried unit. Right now we have the blower power spliced to hot wire so it will turn on. We do not have a replacement controller yet, my Jeep heats up after running awhile and everything but I feel like it’s suppose to heat up faster then it does (right now it takes about 45 mins to be comfortable with a high idle, and or many stops and restarts from running around in town. ) my thoughts are it could be a heater core issue, or my vents are stuck on halfway open cause the unit fried while my boyfriend was adjusting the speed on the fan. (But my fan sounds like it’s running on high) I also have a vacuum leak running from my HVAC under my fender. Would this vacuum line running along my whole under hood be a reason for my lack on heat in my vents? Only my defrosters on my dash blows out a significant amount of heat. Please help. It’s cold in Michigan lol.
I have a 2016 gmc savanna 3500 and the temp heats up to 210 like it should but sometimes when slowing down the temp drops until I speed up again. Any suggestions? Thank you
What are your thoughts on this. YJ ran fine at 210 degrees. I just did a flush of the radiator system. Now, when I turn the key to the first position when the engine is cold the temperature gage immediately jumps to the dash mark just passed 100° (120ish?) and I run warm at 230ish..I just replaced the rear sensor. Thoughts? Thanks in advance and appreciate your help.
If you have a problem with a P0188 or something related to that, always look at your temperature sensor plug to make sure you don't have a bad wire on that, that is what my problem came from. Very simple but it will give a P0188 code like mine has. Check the voltage on the plug if the wire is not appearing broken to make sure you have voltage there. Simple fix though. If it is broken or the wire is off, get a new plug connector for the sensor at somewhere like O'Reilly's.
Mine has been running cold...
I own a 2003 JGC WJ w/4.0 and it just pulled a code P1281 today. That code is for the engine running too cool initially. I had just put in a new t-stat about two weeks before. I took apart the t-stat housing and wouldn't you know it, the t-stat was stuck open. So, if you have that P1281 code or your vehicle takes a long time to get up to operating temperature, consider replacing the t-stat.
I have a 1987 YJ 4.2 and I'm having trouble finding the correct coolant sensor. All the sensor I have purchased run too hot on my gauge. They are not calibrated to match my stock gauge. Can you help with the current part. Love your stuff Thanks
Hey good video I just replaced water pump and thermostat on my 95 yj and my temp gauge keeps moving up and down between 210 and the next lower hashmark got any ideas also no leaks
I am having these issues, about a year ago I noticed fluctuation so while doing an oil change I replaced the thermostat a short time later I purchased a heads up display as I was having issues with the dash being to dark in daylight and having to turn parking lights on to see the speedo well ( the heads up works great) it has 5 readouts one being water temp, everything has been good up until two weeks ago sitting in traffic on a hot day I watched both gauges working hand in hand raising temp to the point of the heads up setting off an alarm so I pulled into a parking lot and let it cool, I found the water was low never having leaks no oil in water and no water in oil I filled water in Radiator and overflow to correct level also tried burping, things seemed to be ok until last night driving 20 miles to a friends before leaving I check water and oil and they were just as they should be and all was good until leaving it was another hot evening at sundown so I turned the A/C on after a couple of miles I noticed the. temp on both gauges was about 130 and fluctuated up to 145 and back so I tried turning the heater on and with my hand in front of the vent the hot air felt like it was plenty warn and right where it should be but the gauges stay low for another 10 miles home, this morning after checking water and oil I went for a ride temp came up and stoped where it was last night 130's-140's after a while I turned the heater on again on was feeling like its normal 180 so now the only thing I can think of is it being the temp sensor........ any thoughts?
Very super useful man
Thanks a ton.
Thank you!
Would this apply to an 05 Jeep GC as well? My Jeep is overheating with a full coolant reservoir, little to no heat for a while in the cab, and the hoses coming from the radiator have a significant difference in temperature feel. At this point I’m stumped on changing a water pump, thermostat, or acknowledging I may have a cracked head.
Thanks, good info!
Can't find a temp sending unit on my 98 TJ???
Did they omit this for this year?
Humm... not sure
Do you have the link to the connector and the sensor for the thermostat housing mine is currently missing or I should say the wires are cut and most likely need a new sensor its had to start a after 5 minutes my jeep gets hot
Wondering if you could help me out new 2000 jeep grand cherokee inline 6 bout it and first few days were great buy today and yesterday started to have problems I think I bought someone's falling apart jeep my list of problems are alot
Hatch won't open
Engine runs hot causing it to not start on hot days
Needs new fuel pump
As well as front axles and rear axles
I love my jeep tho it's awesome I just don't know where to go to look at videos or see what I need to do.
I have an 04 jeep grand Cherokee that the blower motor went out so instead of getting a new one I installed a clutch fan which seemed to work for a while. Now I'm have more over heating issues. Think it could be a thermostat issue?
Love the Jeep bro.
Hi great videos by the way!! 👍🏼 I have recently purchased a 1997 XJ Cherokee ( love it!!)
I have been towing with it this weekend, so working harder that normal, after switching off the engine water was coming out of the expansion vessel,
I have left it overnight, topped up the coolant and driven it to my garage and the temperature stayed at a nice 90°c Do you want this to be a long-term vehicle for us? So what would you do to guarantee a hasslefree future for this vehicle regarding cooling and overheating?
Love you by the way, look forward to hearing from you, Chris (UK).
My manual temp gauge has stopped working but my engine seems to run at a normal temperature and does not over heat even though I haven't checked the thermo. Is it a very good possibility the gauge is the only thing bad? Oh, also there are no leaks. I'm guessing the manual gauge is about 10 to 15 years old.
I always have to stop and think when you say drivers side or passenger side since we drive in the left here is New Zealand. But I like how the jeep uses a lot of metric fittings. I guess it’s got Japanese parts like the transmission being a Toyota unit.
Of all your videos, this was one of them. 😉
Sure was.
Had heater core replaced. Car not running hot but keep hearing water circulating thru like a washing machine when it drains water.
I had a friend flush my engine and add liquid copper. So far the problem seems fixed
Engine and heater run cool on my 98 tj 2.5. Any suggestions?
hey i gotta question about jeeps, i have a 93 zj 4.0, and i’ve done a new radiator, new hoses, water pump, 180 degree thermostat, my clutch fan is fine, but the block is a little rusty. any tips?
I have a 2008 jk and in heat weather my temp gauge goes to cold and my throttle body comes on. What would you check if this happens. It does not seam like I’m overheating
I'm sure you've repaired the lower rad hose leak by now. Every time I find one of those spring clamps on a vehicle I'm working on it gets tossed to the scrap bin and replaced with something that actually works. Even a cheap gear clamp is preferable to any spring type.

Hello sir I’m see you’re video for jeep I have a question for you ,I have a jeep 4L but they have not temperature sending unit and what i do for now
His one for ya!!!
1994 YJ
Temp gauge went to zero! I replaced the thermostat, sensor at thermostat and rear sensor, replaced the fluid, replaced the pig tail at front sensor. Then the temperature gauge now goes to hot!!!! But system not overheating. No warm air either
Jeep patriot has 2 thermostats so htf can you tell then?
I have a 2004 Jeep Liberty 3.7L...during this past summer the a/c blew cold, then hot air intermittently. Now that the weather is cooler and I'm trying to run the heater...same thing except that it doesn't blow warm air nearly as much as it's blowing cold. Help, please?
My gauge reads way too low and when feeling the hoses it's my top radiator hose that heats up not the hose going to my heater core. Is it my thermostat?
Thanks,
Tommy
Useful info😁. I probably would have engine coolant temp sensor and wondered why it didn't fix it.
Hello, What if the temperature gauge shows the temp but the aux fan doesn’t come on unless I turn on the A/C?
Could the overheating be caused by the AC unit?
Okay I have a 99 Expedition when I first start the vehicle the temperature gauge is in the cold position but it immediately goes to normal operating temperature. It doesn't move too much above that and it never gets into the overheating range my vehicle is never overheated and I recently flushed and filled the cooling system. So is the gauge faulty or the sending unit? Thanks
I change both thermostat and temp sensor on a 2014 durango rt and still doing the same only on 40° below weather. FYI I bought an after market stat!!!! And I think the sensor too! And fan turns on crazy high if I'm in a Incline but if I reverse and park it fan turns on only when needed. Same as parking at level ground turns on when needed. Any help?
I keep getting a coolant temperature high and I replaced the coolant temperature sensor 3 times and I still get the read it and check engine light I was wondering if you can help me figure this out . OK I'm explain it in my 98 Jeep Grand Cherokee Laredo 4 wheel drive automatic 6 cylinder I'm getting a check engine light staden coolant temperature high replaced the sensor and erase the code then the light came on . Just happened 3 more times replaced with new sensors and it continues to give me problems and the light is still on does the thermostat or any other part causing this problem if you have any ideas I'd appreciate the feedback thank you thumbs up
I have a 2004 Frontier 2.4L and the engine is surging at idle between 2000 rpm and 2500 rpm. It isn't equipped with a MAF sensor. What else could cause the problem?
Doesn't the sensor on the thermostat housing control the electrical fan? My fan comes on when I unplug it (91 XJ 4.0)
Love that 94 yj
CAMCORDER NONSENSE Thanks! It's been a good vehicle. Very dependable.
My 91 Eldorado fans only work from the fuse with a direct line to the fan which keeps them on all the time when I’m driving. I have a new radiator and thermostat. Hoses are being replaced. And checked. Could it be the sensor as separate from the new thermostat, or Maybe the cooling fan controller because my compressor shut off because of lack of refrigerant. Or could it be the temperature sending unit like you’re showing?
My 97 Jeri Cherokee ac fan wont stop Running when i turn the car off. Replaced the relay in the fuse box that’s in the engine bay and the fan. Jeep doesn’t overheat and the heat is good. Replaced the thermostat when i changed the water pump and coolant.
Okay I am about ready to give up, I have 04 4.0 with 222k I had what I thought was the radiator go out, as I saw coolant dripping down the side of the radiator. I flushed the green coolant out because I understood it to be the wrong coolant. It was very cold still is, took me a few days to get the new coolant in because the radiator is very hard to get in past the ac lines. Changed the battery and thermostat. I have an engine overheating issue and no heat. Problem is I can't get the air out of the system. Is it possible that I had distilled water freeze up in the bottom of the engine? I don't see the fan running. My driveway does not get sun to warm up the jeep. What would you suggest? Is it time to give up on my jeep?
Got one for ya, 1984 CJ7 valve cover gasket, stock has 11 mounting holes, mine has 15, would it be possible the heads been switched? I had to order one from NAPA.
I have a Jeep and was told my thermostat not warming recently my jeep running rough could it be my thermostat? By the way i have 207332 miles love my jeep help!
Closest thing I found ,from looking through this videos , I’ve got an 10 3.7 l commander does not warm up,gives me the code p2181 and coolant is low,at times the lightning light is one,don’t know exactly where but It’s loosing coolant on passenger side under the dash somewhere carpet is wet ...anyone had anything similar that know how to do it yourself?
Thank you!
Were you an MP? You made a statement in your video that made me think so.
My wrangler engine gets hot according to the gauge but blows cold air until it gets to highway speeds then heater blows hot and gauge cools down, I'm thinking it's the thermostat but wondering if it could be something else.
Just bought my 2014 wrangler 4 door. When i first turn on the vehicle the third knob that controls air flow to floor or vents a/c blinks yellow for a min and won’t work. Then stops blinking and starts working. The check engine light came on and said it was a bad thermostat. Is this a bad thermostat? I’m going do the checks from your video tomorrow. Thanks
Thread size of the temperature sensor please?? Can't find the spec anywhere. I've got a renix era Cherokee that I'm in the process of making roadworthy. The thermostat housing that came on my Jeep doesn't have a spot to thread in a temperature sensor. So I'm gonna spend the $13 on a newer style thermostat housing in hopes of putting a jegs water temperature gauge and sensor on it. The jegs kit comes with a 1/2" NPT adapter, just wondering if this is possible before I waste $50. I already have the cooling off my Jeep taken care of, now I'm just looking for a way to monitor my temps as I'm going down the road. Dummy light isn't good enough for me.
I would like to install an electric fan on my 95 yj jeep to eliminate the motor mounted fan. What would you recommend for activating the relay for running the fan. I know they normally use a temperature activated switch but where would you recommend mounting it.
Not sure... I'd have to look into that. Haven't tackled that one yet.
Should the clutch fan start blowing immediately after turning the engine on a grand cherokee laredo 1998, 2x4, 6 cylinder?
No
Thanks man; really appreciate it!
My jeep comes
To temp then stops running and won’t start again for about 20 mins.
Any ideas would be great. Thanks
Christine
In 1:27 safety rules first and i really like it!!!Watchout the rotating parts if your wear a tie (or even anything else as a scarf,a piece of fur around the neck or a x-large golden neck chain if you are a rapper).Worst of these kinds of accidents happen night with cold while being as a sharp dressed man.
Ok but how do you test the sensor or sending unit?
Hello mr i have a Suzuki Alto 2005 i chanched alredey the tampatuor sansoer, but still is not moveing the gechge to hot posatio. And there are not wiring problem we checkeed.. .
The fan works good and the fan starting automatic. ,but the engen i feel is goona soo hot. but only the the tampatuor gechge not Coming op! What can be the problem? Thanks
I have a 2004 Jeep Cherokee Laredo and the engine light is on I had it checked with the plug in at the bottom of the dash and it came up with a code p0161 and it's not overheating but the heater the Overflow bottle is Filling up gauge doesn't go hot but it's not cold either I'm just wondering if that's the thermostat or is it a sensor
My ford coolant reservoir is getting hot rest all seems good but not able to rectify the main cause.milage is also reduced drastically any suggestions plz lemme
Hi there....love the Giants pennant....my temp gauge in the Jeep....91 Wrangler (YJ?)....is flat...dead...not reading anything.....wondering if it is my sending unit....where is that link again.....I will try and see if the fluid moves with the cap off and starting her up...thank you in advance ..~Vince...San Jose CA
Hello. I have 2004 jeep grand Cherokee with a 4.0. I replaced the thermostat months ago. Now I have this code P1281. Does that mean I need to replace the thermostat again? It the coolant temperature sensor? Inside the cab the gauge rises to 210. So I know it can't be the sender sensor. The code reads staying cold for too long. What might you suggest? Is there a way test the coolant temperature sensor on the thermostat housing? Like an ohms test? Any help would be great.
I have a 2006 Jeep Grand Cherokee and the AC cooling fan doesn't run. I applied power from the battery directly to the fan and fan runs. I applied power to the fan before the resistor pack attached to fan and the fan runs. I replaced both the high and low relays for the fan and still no resolve. I replaced the temp sensor and still no dice. Is there anything else I can try
Hi, I have a 2013 traverse overheating...I first checked for leaks and could not find one. Old thermostat replaced looked like it did needed to be replqced but still as I drove temperature needle was moving above normal temp..no enginge light on dashboard so doubt it's the temp sensor..not sure what else to look for..any suggestions? Please help. Thank you..new subscriber.
I can't find a leak anywhere or where it's burning radiator fluid, both my fans are working, and the thermostats seem to be working, my hoses have pressure and heat, but about once every two weeks or once a month or once a week the car will just randomly overheat all the fluid leaves the radiator and goes to the reservoir but doesn't go back into the radiator so you have to take the cap off fill it back up in the radiator and go again do you know what this problem may be? Thanks in advance
Ive got a 2012 Chrysler 200 3.6. it's overheating. I've replaced the water pump, oil cooler, thermostat, hoses. I replaced the radiator about 3 yrs ago. after replacing these parts, it's still overheating but doesn't start overheating until I've been on freeway for about 15 min. only thing I can thing of is the radiator needs replacing. it's the only thing left. I have no leaks at all and no water in my oil . any ideas what it is. I only have a coolant reservoir cap , not a radiator cap and I replaced it as well. any help you can give me?
So I replaced my thermostat, water pump and fan clutch. My 94 jeep is still over heating. I've bled the system as much as I thought was enough. Could I still have aor trapped because I'm still over heating and no fluid is moving through bottom hose.
5:41 Why is it that the block doesn't have that same "u-shaped groove cavity" as the housing? You can see that "groove" in the block itself, but its only got that hole thats open and not the rest of it?
Hello.
I have a YJ-95. Driving the car, I got eventually the check engine turned on. If I turn off the YJ and restart it, the check engine is turned off and it doesn’t appear again at least for the rest of that day.
The fault code I get is the 52: oxygen sensor - rich condition indicated. Time ago, I changed the oxygen sensor. At the beginning it got better, but it started again.
I found in other video that other reason to get a rich air/fuel mixture could be driving the car in a wrong temperature condition. I checked that the temperature gauge shows a low temperature. Thanks your video I checked out that the coolant temperature sending unit is the one that is shown in the gauge and it has an intermittent false contact.
Do you have the part number of this temperature sensor? Do you think this sensor could affect the rich air/fuel mixture or what else could I check?
Thanks
Okay I have a 2012 Jeep Grand Cherokee Laredo check engine light came on it's a low coolant filled up the coolant check engine light went off after driving it for about three months now the check engine light would come on go off come on go off stay on a few days go back off again when it was on I got the code red and it said coolant problem would that because of the thermostat I noticed the car is staying the temperature gauge is reading cooler all the time I said I really warming up and going where it should be but I'm not sure if you be the temperature gauge or or the thermostat the car does warm up it gets warm but it seems like the heat dies off again and then comes back on and dies off
