Jim, you are a kind soul, I can hear it in you voice. Helping your fellow man by sharing your knowledge is a special gift. And I agree with your "all things stop for coffee" attitude. I never considered the danger of cracking the plastic neck on the radiator & heater core, but now I will. Lastly. . . . . I better stock up on some Hi-Tech paper clips!
Have you ever seen oil in the antifreeze reservoir, or is it from the hoses?
My fan works I seen it ....my upper radiator hose bursted on me I have replaced it ...needle still at the top hot when I leave car running trying thermostat next ...I have felt hose (upper) when car is running don’t feel any pressure at all any tips...???
Do you need to drain all of the coolant if you are just swapping out the switch and not the hoses?
No. You don't need to drain the coolant. Just remove the hose on the thermostat side, replace the thermostat, and put the hose back on. Some coolant will spill and AIR is going to be introduced into the system which is not good so look up how to bleed the coolant system for this car for when you are done replacing the items.
He should of mentioned that you should bleed the system because you're supposed to do it either way when doing this job whether you follow his instruction (draining the coolant) or mine.
Air in the system (from not bleeding) will cause the engine to over heat if not done.
I have a 98 Honda Civic and a few weeks ago it over heated. I noticed that the coolant in the over flow tank was boiling and the cap was off. Don't know if it was pressure from the engine. I'm not a mechanic so bare with me. I had the thermostat replaced about 3 months ago so it's fairly new. The car has 194000 miles. One other issue I've been having prior to the car overheating is that I don't have any heat in the cabin. Don't know if the heater core is no good or just clogged. Could the water pump or head gasket have anything to do with either of my issues. I did check the cooling fan and it turns on. Any advice as to what I can check next to fix over heating. I'm going to check hoses again. Thanks in advance.
you're definitely A Good teacher I am a beginner with a older civic and you're explanation is ON Point
thank you for stopping by the shop
@@jimthecarguy we need you in cali
it all started one day when I went to start the car the whole car Shook and I had to turn it off for a minute and then restart it again and it started overheating from then on
My 96 accord is making a very loud "wwrrrrrrrrrraaaaaaaaa" noise when the I accelerate after the car has been on for a while. Any ideas? It is becoming very annoying and I just can't figure it out. Also, it does it non stop if the AC is on but only after a while when it is off. Any help
Is very much appreciated.
Sir Jim, How about the coolant temperature sensor? what happens if its defective? Thanks.
If the sensor is defective then the fan will not turn on and it should be changed.Thanks for watching.
I did all that but replace the hoses on my 01,,deleted cat also,,I believe is the thermostat
..nah..tried gasket sealing..work for a mn,,after flushing the radiator...it was the head gasket,,previous owner dint took care of the car
Replaced EVERYTHING and it STILL overheats....Ugh!!! Any ideas??? Replaced radiator and thermostat , and temp control switch... both fans work.... checked all fuses , and relays..... fluid all full , no leaks!!!!!!
This seems so helpful except for the fact that (I have an 04 Honda Civic) I've replaced my thermostat, my coolant isn't leaking, my fans work, and my car still overheats if I stay idle for longer than one min...
Chelsey Bray i got the same problem. You ever get that problem fixed? If so, how?
Did you ever get it fix? How??
Same pronlem here any luck?
@@kelchanel0012 did you?
@@vladisparedes5626 did you?
I have 1996 honda accord my fan just keep on and off. It's that ok ?? temperature gauge stays in good
Did you figure it out. This dude is the Herr to help us with questions just Herr for the views.
I own a 2003 Honda Accord 2.4 litre with a new thermostat housing and new thermostat. One morning it was cold i started up my car and let it warm up for 22 minutes and then the gauge went to hot i did see very little smoke from the radiator. The cooling fan did not turn on at all i don't know what the problem is, do you have any idea 💡 what the overheating is about? Thank you !!!
I have an odd issue in a 2004 Honda Civic, I’ve replaced the sensor that controls the fans, temp sensor, thermostat & burped the coolant
Car still overheats..
does NOT overheat when I have the AC running .. any clue is to why ?
Im used to hearing peoples cars overheat when they have the AC on but mine happens to be the opposite situation lol
My Honda civic 2007 is overheating and showing engine ckeck light. And also not accelerator when i step on the accelerator during the period that is overheats. But when i leave it for sometimes, i wil accelerate and the engine light will go off.plshow do i solve this
Tried to do this but for some reason my cooling fan never turned back on and coolant never circulated through the top and bottom hoses. Any ideas?
Great tips on the hose removals. Thanks. I'll be repairing an overheating Sonoma for a friend of mine. Being gals, neither of us are experienced tho I've had a mechanics course so I know the layout and functions. I'm always looking for DIY before taking it to a garage for the big ticket stuff.
What is the major difference between a reverse flow system and a regular flow ? Is it literally reverse flow or is it just a term . Can you explain ? thanks
I just replaced top and bottom radiator hoses. I also got the radiator cap brand new. When the car first overhead a week ago. I found the bottom hose to be the culprit. Thus the reason I got new hoses. Thermostat got out in about 4 months ago and new water pump and timing belt done two weeks ago. I out antifreeze in run car and I touch the radiator cap but it doesn't feel hot when the car over heated. I found that weird. Also, that little vent over the radiator seems to release steam when the car overheats. Any ideas. Thanks in advance. I'm not much of a mechanic but trying to save money anyway I can.
It sounds like your new thermostat is actually ; it happens sometimes. Replace it again and bleed the cooling system.
thanks for not helping me.....
+Allison Currie I'm happy to have helped.
I am having this exact problem now I know what to fix.
Just did my thermostat yesterday thinking that was it but it was not.
Great instructional video! Solved my Honda problem. Thanks!
Thank you I'm happy to help
Is it harmful to drive car with radiator heat sensor bypassed???
Great job and I learned a lot. Especially the razor blade trick on the hoses. Thank you so much
have a Dodge neon sxt 04 had a bolt stuck in there so I made my own bolt its snug good. no leaks. Didn't start over heating until I changed thermostat. Blows heat did flush only cool stay at right temperature if I have heat on
Buy toyotaaaaaaaaaaaaa for the love of God. Don't do cheap fix do a permanant fix
did not work on my 2003 honda new radiator. is it waters pump?
So I have a 96 civic thats overheating, well from what I understand it comes very close to overheating, the AC/heat don't work, and from what the previous owner said I should replace the head gasket. When I originally owned the car years ago it had an overheating issue and I ended up replacing the thermostat and a couple hoses. But when I tried to "burp" the cooling system like people told me to do after opening the system up, it wasn't burping right, it would spit coolant up while fluctuating RPM. I'm just wondering how I can diagnose what exactly the problem is, thermostat has been replaced, a couple hoses, and the relay to the cooling fan cause it was burnt out. I just don't want to end up spending a bunch of money replacing things that end up not fixing the problem. Would a bad head gasket cause overheating issues on this scale?
When head gasket fails, you will have seemingly disappearing coolant (no external leak) and a steady stream of white smoke from exhaust pipe when at operating temperature.
Save good timing having problems with mine hope that all
I have a Tata Nano, radiator fan is not working, checked fan is ok, changed Cooling temp sensor, checked fuses and relays, could not find anything wrong, lastly direct fan with starting key switch though a push pull switch, fan is working. Pl. suggest how to solve overheating in normal way.
Thanks for watching.
I have honda civic 1997 I have the same problem the car overheats the fan works but it's too hot still works but it doesn't stay on until temperatures goes down there is no leaks the thermostat was replaced but still overheats what do you recommend my mechanic say replace all the sensors might stop the overheating what do you think
Hello. Did you ever find out what the problem was?
just fixing honda now so awsome glad i found this vid
My 99 Civic cools normally on flat roads but pushes the antifreeze into the overflow only on long steep hills where it has shifted down for long periods. Temp. gauge stays in normal range until. I've changed everything including the radiator but haven't changed the pump yet which I guess is the next step. Any magic tricks, anybody ?
Well done Jim. You seem to have lots of Hondas in your shop. Not too many in the north country, mostly trucks up here.
Steve Rob Ya Steve Honda is the most popular car down here.
SAME Car I have the same problem car over heating and Fan not working I replaced the thermostat switch by thermostat the cooling temp switch and the relay and the fan is still not working I know the fan works .I hooked it up to the battery.
chris Is there power going to the cooling fan?
Great video, my cooling fan only runs when my air condition compressor fan runs. (2012 honda civic) any idea what could be causing that? Thanks
Did I miss gasket install? I think you should cover importance
The seal is built onto the Thermostat. NO gasket.
Jim I have a 2003 honda civic Ex, My coolant isn't circulating. Top hose gets very hot Bottom hose stays cold. Replaced the Thermostat today still staying cold. The car sat up for 5 yrs before I purchased it. Could it be clogged? I dont want to buy another radiator if I dont have to.
Hi Jim, i have 05 Honda civic the radiator fluid away fill up into reservoir .please let know why. Thanks
There are a few things that can cause that the first is the radiator cap is no good .The next thing to check is the cooling fans and check if the car runs hot.Keep me posted.
Hi Jim,the radiator cap is changed and the cooling fan but still have fluid fill up reservoir.Thanks
@@tomdanang6788 It’s the head gasket
So my temp needle goes to half then prolly 3/4 of the way but the car doesn’t overheat, I’ve topped off antifreeze too. Could it be a faulty thermostat? It shows slight smoke from the hose connecting to engine but it’s only noticeable in cold cold weather
Also to note when I turn on heat or a/c temp needle stabalizes
Thermostat, water pump, blocked radiator, cracked expansion tank, head gasket, split hose, leaky Temp sensor, bad fan, bad relay, bad wiring, or bad ecu.
Hey Jim question why my 99 civic radiator fan delays to kick in, it kicks in when the temperature needle begins to rise
Was that the problem with the car or was it something else ? because i’m having an over heating problem with my 2007 Honda Civic DX.
Great video. Do you like the screw on clamps better then the squeeze on type?
tubejim101 To be honest I do like the spring clamps better because they never need to be tightened again after there installed but in this case they were very rusty.
Yesterday my Honda was over heating I checked the leaking I didn’t see nothing Leak I filled the coolant the coolant gone fast I don’t know what going on please give me some clue
You are excellent professional, were you are located Orlando, FL ? my Honda accord wagon ex 1997 Sometimes it heats up but when it runs it is getting cold down , when stop in the light signal it heats up,I do not use coolant just water , you think it's the thermostat or fan I see fan running and stop, how much is the average cost for repair give a idea thank you very much for help
Thank you an excellent, thorough video.
Thank you for watching
Can't find where the water is going when it is running no sign of any leak but I can tell I put water in radiator and it is going somewhere can you tell me what this is my car is sitting for 6 months I paid so many people nobody knows where it is going I am wasting money there is no sign of it leaking through water core or the hoses no sign of leaking there is water lil leaking through the tail pipe
Hi Jim good video. Just wanted to know what you meant by running hot-expansion tank full of coolant. My accord is doing this plus when I take off the radiator cap, looking at the rad. Hole I can see fluid missing it's only on the very top of the radiator. Amy ideas? Thanks
I've replaced hoses, thermostat, radiator, temp sensor, now changed the fuses, I am lost :( please help
I have a 05 Honda Civic and it's showing indication of a similar problem with the thermostat. The fan don't turn on, the temperature gauge immediately exceeds past the normal range, and it's leaking anti freeze. is it a easy fix?
my sx4 having a heating problem after after run in heavy traffic or sometimes early morning start a cool engine
When my car gauge showing overheating i always noticed that radiator out hose pipe temprature temperatures is very cold while the radiator in pipe is very hot
I had change the thermostat valve or thermostat switch the new radiator is also install all pipes were also checked and replace but the thermostat valve stil not working properly
sometime it's work nicely for 100 km or sometime stop working in anytime km what to do please help
changed my alternator on my 92 honda civic i just bought, because battery kept dying over couple hours. now my car makes a chirping sound, and i drove it around a couple blocks seems it was overheating. what could be the problem sir?
So I have a 98 Honda civic Dx , I replaced my fan and relay switch along with hoses but it is started over heating again . I dont have an air conditioner in my car . What else do you think could be the problem?
I noticed my friend's similar Honda leaks water but noticed its not from a radiator as he told me, but from under his engine. Not so sure, but I told him there could be a leaking hose or coolant reservoir, if the car has one.
Hi Jim, Awesome video and explanation, awesome professional work. Can you tell me the make and where you purchased the power tester? Also, can you comment on if I only have heating issue after 3-4hrs of driving in 95F+, heating fan sensor replaced, thermostat works, no leaks, fan turns on as it should...possible issue? 2000 Civic LX , 115K miles. Thanks Steve
Hi Steven, The tool I'm using is called a Power probe and you can find the company on line.If not let me know I will get a number for you.As for the overheating the thermostat may be sticking .Was it replaced?
No, it has not recently, but what would lead you to believe it is the problem?
Because if there is no leaks ,the sensor is new and the coolant fan is turning on and off.The only thing remaining is the radiator or the thermostat.Start with the easiest first .The thermostat.
Hi Jim, just wanted to send a thank you and followup. I pulled the old thermostat and testing in water, it was rated for 170F and did not open until well past 208F, probably closer to 212F boiling. Going to do full bleed and road test and refill and Ill let you know, but I think its solved. I also pulled relays and cleaned contacts, they had some anodized areas and carbon (sanded them a little).
Great keep me posted.
Excellent Mechanic Jim well done on the tutorial , your a Champion mate all the way from Australia Ciao !!
Jimmy is the best
I have the same problem my car heats up i did a direct circuit cut so the fan stays on so im guessing could it be the switch than !??
Jim if that switch wasn't the problem what would you check for next? water pump?
Same car mine has the p0505 code and also overheating fan comes on but the temperature keeps going up
And out of no where it seems like it wants to turn off and its not generating enought power could some one help me out pleasee!!!
P S nice video
Thank you I'll appreciate any suggestion you'll have
NICE! Very good diagnosis on this Honda.
Joe's Auto Electric Thank you Joe
Jim, I’ve replaced the radiator (with flush), the thermostat, engine cooling sensor, fan relay and have had the gasket checked. I just checked the radiator fan via this method and also the relay again. Why is my car still over heating? Water pump? Faulty thermostat?
Hi Eric, i have a problem with my Honda 150 carburator engine 92 -96, the bottom radiator hose stays cold yet the top radiator hose is super hot, i have removed thermostat to check and it does the same naturally just takes longer. i have fitted a new radiator and cap and a new fan switch at Thermostat housing, what could the problem be.
.
Hello just wanna ask its ok to use car without thermostat i check my car radiator is ok and fan one of my colleauge told me maybe thermostat problem its ok to remove and drivr my car what the cause if i remove them?
Good question . You do need to have a thermostat in you car to regulate the flow of coolant. If you take it out and drive for a long time your car will over heat and at low temperature the car computer will not go into closed loop causing many other problems.
Thank you for the video very detailed. I'm here looking also to auto repair my car honda accord 99 sedan. It gets very hot in the highway. When I open the radiator and turn the car on I cannot see any movement of water or split. If I tight the big tubes with my hand I can see the water overflow the radiator. If i turn on the heater I can hear a noise coming from the water pump area . My car ran out of oil and got very hot and since then I have this problem. I hope that info is good to guess the problem. I hope is thermostat. Thank you .
+daniliver The thermostat could be the problem but you will need to check the cooling fans to make sure that they turn on.Keep me posted.
After couple blocks mine wants to red line,Replaced thermostat, radiator, radiator cap, Both fans, coolant fan/condenser fan,Temp/fan switch, ECT sensor, head seems OK no leaks the radiator is holding coolant and reservoir is where it has to be fluid wise,I noticed my coolant fan is not doing its job 3/4 till red the fan won't kick on? I just replaced the Fan control switch and ECT sensor, the coolant fan only comes on with a/c on which both fans come on, I'm stuck guy, it won't even cool down when I turn the heat on, I'm not sure what's up with the fan? The fan switch is new from autozone duracrap brand, I was in a bind.
Thank you for stopping by the shop
Soo...it might be my cooling switch?? Cuz fans not running and all the fuses are good? Jus took out my thermostat.. Now it not over heating.. But no fans??..
shawna yesslith You should not remove the thermostat .You should repair the problem and reinstall the thermostat.Cars today need a thermostat to achieve the correct temp for everything to function properly.Jim
Very clearly explained and visually easy to see what you are doing. Appreciate your time and knowledge.
I have a 2004 CRV and it overheats when stopped for a bit in traffic but once I start moving it cools back down. This only seems to happen when it's hot out. The air blows cold from the AC. It also cools down if I crank the heat up when it starts to overheat. Any help would be appreciated
It _your_boy_Johnny B ..water pump?
I am having this same problem, my 91 civic is overheating I just replaced the temp sensor, temp sending sensor, thermostat, and relay and It is still not turning on, if i take the fan and hook it straight up to the battery it comes right on. Do you think even though the coolant relay is new it can be bad? Thanks
Did you ever figure out the problem? I changed all three sensors and thermostat and bled the system.
Jim, the problem ended up being the head gasket. Thankfully the head wasn't warped. Our Del Sol is back together now and running fine. Thank you for your time.
Great thank you for the update. Watch for the next free tool giveaway coming soon.
Hey jimthecarguy I have a 2005 civic and it runs hot after driving it a while! The gauge goes up and down! I need help trying to diagnose the problem
Same. Did you find the solution to your problem?
2005 civic overheating after going bout 60mpg on freeway then stoping for a red light in town its ok do you think its the same switch issue
+Liliana Sualez Just so I under stand .The car over heats at 60 mph but not when you drive in the city?
jim how about my 97 model honda city my rad fan..is not working if i will try to connect the paper clip to the sensor like your vedio only the ac fan running.but if i will direct to the battery the fn rad is totally working
Replace the switch that is located on the housing like he did.
Hello! I drove my car for about 5-7 months without a oil change. When i finally was able to get a oil change my car started to over heat. I have a honda civic ex 2002
I just turned on my car the Temp is about to past the middle mark and both the fans not dont turn on but they turn on once I put the AC on blast
What does it mean if the top hose is hot but the bottom hose is cold?
my fan wasnt working so i did the papaer clip and it worked replaced the fan switch but still over heating and no leaks... only overheats while im sitting still and not alll the time. any suggestions. fan comes on but still over heats after driving for a while when i stop
chris carver my 93 civic started doing that today
can i exchange my 95 civic single fan radiator with double fan radiator is that possible in civic 95 jim bro??
+Umar Tariq No you will not be able to do that on this car.
Great video. Thanks for the help Jim
this is awesome! i bought an 04 honda civic from a friend and it had some overheating issues, i thought i had to replace the whole radiator or even a head gasket! this saved me so much time and money. thanks
Great .I'm happy to help.
Would it work without having to change the thermostat? Thanks for any answer in advance.
yes but if you walk 1 mile might as well walk 2 : )
Would you have any idea why my Honda doesn't over heat when my thermostat is out but over heats when it is put back in ?
It's an 01 Honda Civic lx
Great presentation and well explained it is really helpful to me a newbie on this overheating problem thank you very much
Thank you for watching and your feedback.
I mean Hi Jim,sorry
.
Is the fan switch you mentioned, is the same as the sensor for the fan , thank him awesome video
.
Mechanics make a bad name for the whole industry by finding a problem, then changing 15 other parts with it because they might go bad some day in the future. If it ain’t broke, don’t fix it. Best way to create a problem where none exists is by disturbing parts that are continuing to work just fine. Otherwise it was a decent job of partially troubleshooting, then making an educated guess.
eh beg to differ had a guy the other day , change one lower control arm with ball joint attached driver side , recommended he do the other side as well , he thought i was trying to get over on him , about 2 weeks later get a call his passenger side lower control arm broke on the freeway LOL
@@panthers559 I don’t get why that’s funny. I also don’t see what that has to do with what I wrote. Left and right are two different sides of the car.
Also, you didn’t disclose to us any info about the condition of the other control arm.
I have the same year honda civic i noticed that the gauge goes to the middle and im already stressing that something bad is happening to my honda. I had the water pump replaced and timing belt. I switched the hoses too and thermostat and coolant as well. Could this be of a bad radiator which i don't see leaks but notice the reservoir tank has powdery stuff by the end of the small hose to the radiator cap.
The middle is not high. What is the outside temperature?
@@jimthecarguy was 98 degrees
HEY ERIC CAN I USE A T PIN TO CHECK THE TEMPERATURE SWITCH
I hope you read this
I have a 2004 Honda Civic 1.7 L
I put a new radiator in a few Months ago and there were no issues. Now I am having a problem where the temp goes up. I replaced the thermostat that’s for 175 degrees, cooling fan sensor and the radiator temp sensor. I’m still having the problem. When I drive it’s fine but when I’m trying to park or at an idle it starts to go up. Thanks a bunch
how did it stop. i have exactly the same problem with the same vehicle
@@emileriderman hello, I ended up getting rid of the car but if I remember correctly the water pump needed to be replaced. Still not sure if they was 100% the issue tho. Best of luck
What should temperature be at
Curious about my 1993 Honda Del Sol. Replaced the radiator, thermostat, both radiator hose (heater hoses replaced last year) the thermoswitch for the cooling fan as well a the ECM temperature switch. Car runs fine and stays in normal range yet fan still doesn't come on. Used a jumper wire to test fan, works fine that way. Worried the head gasket may be bad. Any input would be appreciated.
Do the fans come on when the temp goes over 3/4 on gauge?
@@jimthecarguy it doesn't get that hot. Found new thermostat was bad and replaced. According to shop fan supposed to come on 195 to 203 degrees. Seems to be bubbling in radiator which I thought was air pocket... bleed it many times. No leaks yet coolant get low and overflow tank is full. I think head gasket but not sure. Thank you.
Hello sir, nice video.I have a '94 Civic eg 1.5 16v 90hp and i have a problem that i don't know how to solve it.First time the water was boiling in the expansion tank and the fan doesn't work.When i went at the mechanic, he said that the thermostat is blocked or something like this and i need to replace it and to replace the coolant temperature sensor too.I replaced the both pieces and now the fan still doesn't work.Another problem is the water is still boiling in the expansion tank even when i run with the electric fan on direct(works continuously). I hope that you can help me and sorry for my bad english, have a nice day sir !
It was the water pump, thanks anyway !
Thanks for tell us. One question: when the car was overheating was it cool down when you accelerate or rev it?
Helpful. We can't all afford paperclips though.
Thanks for watching.
Very very well explain thank you for taking your time and help others
Thank you
I have an 02 Honda Civic and it keeps overheating. We changed the thermostat and it seemed to do the trick for a couple of weeks and would only overheat in cold weather. We also bypassed the fan so it would always be on but it still overheats at idle
Mine does it too. Did u ever figure anything out?
Did you ever find out what was wrong? I have the exact same problem.
