I don't think I've ever seen an engine bay so clean on this old of a car!!! Well taken care of, I'm impressed!
it's not hard to make and keep clean the engine bay if you clean it periodically, say once or twice a year. So long as you cover up areas sensitive to water (starter connections, alt, air inlets) and use low pressure water. It also helps to warm up the engine a little (but not hot! never spray water on a hot engine - )
my camry ateva has the same motor and its pretty clean for 273,110km
Did mine today after watching your vid. Mine's a 2000, so there were some differences, and I found access to the housing was MUCH easier after I removed the air intake hose (two philips screws) and the heater hoses (pliers, a twist and a pull), and one vacuum hose (same pliers, easier pull). Man! I could even SEE that back nut! Thanks for the intro and inspiration. It's a dirty job, takes a bit of time, but I just kept telling myself "slow down," "you're not in a hurry," and it was done in a little less than an hour, even with the hangups I found along the way.
Awesome, glad you got it knocked out. Thanks for watching!
Watched this and I did it thanks for inspiring me that I could do it myself.
Glad the video helped you out and inspired you to tackle a great DIY project. Thanks for watching!
Great vid. Yeah its tight back there I couldnt even unplug the VVTI back solenoid because all the wires back there and hoses, wound up taking the airbox off the throttle body to make room.
Your engine bay is so freaking CLEAN!!! I love it! Can you share how you clean and how often you clean the engine bay? Btw, what's the inside diameter of the plastic tube to direct the coolant draining? Thanks.
I generally clean the bay once or twice per year on daily drivers. I prefer dilute Simple Green, a variety of horsehair brushes and wheel woolies, and finishing off with spray wax on painted surfaces and a vinyl/rubber dressing and conditioner on hoses, plastics, etc.
I can't answer the question on the plastic tube as the car was totalled a few years ago. Sorry about that.
Hope that helps, and thanks for watching!
Yeah so so clean, like do you not drive it haha
Don't use Krytox grease on the feed tube gasket. Replace the gasket with a new one (part number in description) and install it ungreased.
why would one use Krytox grease over a silicone based grease for this application?
Did the dreadful valve cover & plug seals - turned out pretty simple. Run Sync Castrol & engine flush oil once a year. Ignition cylinder lock and transponder installed and reprogrammed TKU, YOU-Tuber's help. Found a new aftermarket heat core installed attempt, that the original owner just needed the pipe retainer c-clips correctly installed - it was so hard to do. Paint good. Online aftermarket parts and prices have done good. Still needs crack belts change and a slightly noisy radiator right side fan motor. Transaxle seal and rear main oil @class 2 leak. The headlight lenses need refinishing. Thinking on changing that ECU sensor, too? 400rpm idling restart occurs even after a drive, it has no error codes. Spent around $6k so far. It's not bad than being locked in around a MSVP $37k or financing for a $75k@6years sale. Wonder if others have a similar Camry living? Wow devastating crashing yours'! Did you get another Camry?
The engine is immaculately clean
Thank you, and thanks for watching!
Fyi the thermostat link brings me to a gasket. Thanks for the video anyways. Very informational
Great video very help full, thanks guy
Thanks for watching!
thanks for the information and explanation 🔥
Thanks for watching!
This is great, but what was the sensor on the thermostat housing? The one you see sticking straight up out of it at 7:50? You mentioned the other two earlier at 2:45, which was the ECU sensor and the cluster gauge sender.
Water Engine Coolant Temperature Sensor.
So someone on Amazon had a comment that said the new part did not come with an o-ring p# 90430-12005 and that it was needed, they also implied not to use thread sealant? You comments?
Dude that is the cleanest old engine I ever saw
Thank you, and thanks for watching!
@@redonKiLaus We own two cars with this engine, 2001 Solara with 250,000 and 2002 Camry with 200K - best, most dependable cars I ever owned. The paint is peeling off mine but It'll take a lot more then that for me to get rid of this car! They don't make em like this anymore.
@@robertmaybeth3434 Indeed they don't, it's tough to find anything close to comparable to these older Toyota/Lexus vehicles! I'm a huge German car enthusiast as well and while the physical build may be better on many of them, they're not made to the same reliability quality standards of a good old Toyota.
@@robertmaybeth3434 My 2000 Camry (Japanese) drives better than my 2014 Camry (American), both purchased new. I'll retire the 2014 Camry before giving up on the 2000.
@@kimchee94112 OMG yes! My 02 Camry, V6 is the best car (of 12) I ever owned. Even at 200K miles I'd still pick the Camry over most new cars ever made. It has the 1FMZE V6, the so-called "sludge" engine and I got the recall notice but just ignored it, the recall was for people that actually obeyed the "recommended oil change intervals". I always change at 3 months, period, I knew I had no sludge. BUT once, i changed someones oil (they owned the Toyota minivan with this engine). I gave it back, then they told me it started to smoke and lost power just from the oil change! They took it in, the shop pulled the pan and covers, cleaned out the sludge (this person didn't change their oil much) and gave it back. It ran ok but used a qt in 1000 miles after this.
Tank you
thank your video was very helpful I have a 2001 camery has the same set up . but have ran into another problem their is a machined hole just below the thermostat on the engine block right where the transmission is bolted up to what is this the coolant leaks right out of it
That might be the block drain or may be a freeze plug. Either way, that leak needs to be fixed. Thanks for watching!
I did this job on a 2000 camry just today just wonder what Antifreeze did you use i used a 50/50 mix it had red in it but the 50/50 was any color compatible so iam not too worried i guess burping is not very hard either with this motor pretty easy for the most part imo.
I always use Toyota Red or Pink on Toyota vehicles. Thanks for watching!
How can you test if the cooling temp sensor is bad? The fans on my 01 camry wont turn off even if the car is off. i have replaced the relays and that didnt do it. My next guess is the temp sensor because thats what is telling the ecu that the fans need to be on. Any advice, please help!
Unless there is a wiring issue to the ECU keeping it on when the car is off, there is a short somewhere causing the fans to stay on. My first guess would be relays - there may be some that you haven't yet replaced. It's definitely not a coolant temperature sensor issue. Thanks for watching!
I have an 02 toyota solara, 3.0 lier engine.
Autozone told me a 180 degree thermostat is what is recommended for replacement.
A mechanic told me a 190 degree thermostat is what i need?
Which one should I buy?
I'd purchase per Toyota spec. Thanks for watching!
Great video. Do you know what is the temperature sensor on top of the thermostat housing? Looks exactly like the temp sensor that you installed, which begs the questions what is the difference between the two sensors?
They may be the same - I'm not entirely sure which sensor you're referring to since I no longer have this vehicle, but my guess is for the ECU to compare the two and come up with a delta for engine/emissions management. Thanks for watching!
@@redonKiLaus I too was wondering the same question. Then you says you not sure what sensor he was referring to because you don't have the car anymore. Then watch you're video and you can see what he is referring. 6;11 through 8;14 mark you can clearly see the sensor. I must say the video was perfect. You're answer to this question nayy not so good.
Daimmmm, pretty clean engine bay for a 25 year old car!!
Thanks, and thanks for watching!
What sensor is connected to the thermostat housing ?
I see no one gave a clue, yet. I'm guessing. Could it be the direct inlet temp control open and shut sensor for the fan.
Thanks for the Video! I have a P0128 code, "coolant thermostat problem" on my 2002 Lexus ES300 and was wondering if its most likely the thermostats problem? Also did replacing those parts fix your cooling problem? Thanks in advance.
The thermostat may very well be the culprit in your case too, especially if your temperature gauge shows that the car takes a long time to warm up. Replacing the thermostat fixed the issue in my case, and is a common failure point on any vehicle. Hope that helps, and thanks for watching!
@@redonKiLaus
How long for the P0128 check engine light to go away? A few weeks on a daily driver?
@@kimchee94112 Likely around that long if the root cause is resolved. You can clear it and ensure drive cycles complete, alternatively. Thanks for watching!
Hi there, what is the sensor on the thermostat housing? Does that one control the fans from kicking on or it was the one you replaced at the top of the engine.. m
It's just for coolant temp sensing, not sure if there is another one that controls the fans or not on this particular car. Often times, there is also a sensor on the radiator that primarily controls the fans, with the coolant temp sensor sometimes contributing into the equation. Thanks for watching!
@@redonKiLaus I checked all around the radiator, but couldn't find any additional sensors. There is only two on the thermostat housing and a additional two where the coolant cap sits on top of the engine. I replaced all sensors except the one that reads the dash temperature.
What's the sensor on the housing it self, I ordered a coolant sensor and thought it was on the housing but according to your video and others I've seen it's on the opposite side
Did u figure it out? I saw the sensor on the housing looks like the coolant sensor 2. So let me know what u find out. I still get a p0128 code after replacing the sensor near the cap.
@@TheKnceoincusa We kept driving it, got into an accident, we no longer have the car
Kept driving it without
changing either sensor
no videos show how they get the sensor out, i physically haven’t been able to get to it with a socket or wrench😡
I have an 01 Camry,it’s a 4cyl,the radiator cooling fans come on right away,when I turn the key on. This keeps the car from reaching its operating temperature. Especially during warm up. I replaced,a new sensor, and replaced,two fan1,fan2 and fan3,relays,the fans remain on. Does the coolant temp sensor wires,one of them should have power when you turn the key on? Thanks
I believe one of the sensor wires should have switched power indeed. What you describe sounds like a fused relay. Thanks for watching!
Thank you so very much for this well made video. You covered everything I needed to know and more. You inspired me to replace the thermostat. I could not find any good video on this topic on RUclips so thanks a lot. Replacement complete and now waiting for the code P0185 not to return. All looks great for now, need to run the car another 100 miles before DOT inspection.
I'm glad the video helped you, and thank you for watching!
thank you 1998 Toyota senna XLE
Thanks for watching!
Does the ECU sensor have anything to do with cat not starting in cold weather? Please help me
It could, depends on the sensor and vehicle configuration. It would be unlikely to be a coolant temp sensor causing a non-start, though. Thanks for watching!
Sensor locations 2:43
Got more insight.... But you did not give part numbers to both sensors used. Also Amazon is garbage and never has good pictures
If I dont need to change the fluid can I just use the top drain plug to drain or is it not enough
It might be - worst case, you spill coolant and need to mop it up with paper towels and wash out the engine bay. Coolant won't hurt anything if spilled. Thanks for watching!
Would the p0128 cause my cat to not be able to reach the proper temperature ? Because I’m trying to get a smog, I already got the knock sensor fixed which was the only code to pass smog but after the work the car was not ready so I drove it a 100 miles like the smog tech told me. Took it to autozone to use scan tool to see if it got ready after 2 days later and got the p0128 code...
I'd guess it's the thermostat stuck open based upon the code alone.
redonKiLaus After getting the thermostat repaired and completing a drive cycle my car’s cat got in ready status, thank you. I always noticed I would be running my car and the thermostat wouldn’t be at a high level for how long I’ve been running it . It’s now at normal levels . Emissions system running very smoothly, just passed smog yesterday.
@@nicholascurry5085 Awesome, glad to hear it's working!
Why do you add water can't I just put coolant in there?
You can if it's premixed and of the correct type, I sometimes top up with distilled water if it's a very small amount. Thanks for watching!
hi, can. you tell me the name from were you add antifreeze or coolant were you removed the top from im haveing trouble with my car its a 99 toyota camry nd the part were the coolant goes its broken so the top wont lock in and i cant seem to find the part anywhere.
Are you referring to the radiator cap? That is the part that covers the inlet to the radiator where you pour in coolant - if you are trying to add coolant and it's not through a tube covered by a round cap with two "wings" on the sides, then you might be looking in the wrong area. Hope that helps, and thanks for watching!
What does the sensor on the thermostat housing control? Does it control the cooling fan?
Not sure, that's a question for the service manual and schematics. Thanks for watching!
yes, the fans
@@JustLikeGreta You are right. Finally figured it out through trial + error.
Thank You.
@@ababner317 what part sensor comes there no one knows even the dealer doesnt see nothing there in diagrams but my engine is a 3vzfe and there are a sensor in the thermostat housing near the water pump
On the thermostat housing theres a sensor🤔whats the name of that sensor?
Not sure which one you're referring to other than the coolant temp sensor this video features, but I don't have this vehicle anymore to reference. Sorry about that.
Are you talking about the coolant temp sensor?
Is it 2001 Model?
This one is indeed.
Good video, have to say I can't stand working on this vehicle. I find the lack of space and seemingly ad hoc design and lack of due consideration for the mechanic and customer alike, just puts me off having a Japanese car. Unfortunately, my wife has one of these and given the quotation from repairers, I would prefer to put a bomb under it. I stick with MB. I have so much joy working on them. Thanks for your guidance.
I love working on my MB vehicles as well, although I generally find Japanese cars easier to work on, with one exception to that being the Camry in this video. My Lexus GS is extremely easy to work on with an inline 6 and intelligent layout on the interior as well. Same goes for my MB S320 though, well thought out for the most part. Thanks for watching!
Cool temp sensor is the same/is as a Engine coolant sensor correct ? Lol
Yes indeed. Thanks for watching!
I don't believe that having the heater on makes any difference. The heater core is always full flow. The heater control only changes the air mixer louver in the ducts
Depends on if the vehicle has a heater shutoff valve. Many do, not sure if this is one of them, but it's a good "best practice" when bleeding the cooling system.
Thanks for watching!
@@redonKiLaus that's cool to know. I'd never seen a heater shutoff valve, but I've only worked on cars I own (so a much smaller sample than a proper mechanic). I might look into whether my classics could benefit from aftermarket ones.
@@twinprimeable I'm not a mechanic either, just work on my own cars, too. I'm sure they're out there in the aftermarket world too.
is someone taking a shower or was it raining.
I did this during monsoon season here in Arizona, so it was definitely rain. Thanks for watching!
@@redonKiLaus funny its raining in az and I'm watching you video. Your more than welcome to come over and replace mine.lol
Why are you unhooking the battery for this job people don't realize if they unhooked their battery for more than 5 minutes it can erase all the codes for up to a day don't unhook your battery unless it's an alternator problem Orion electrical problem in this case it's neither
General good practice is to disconnect the battery when working on any electrical systems. Static discharge as well as shorting of components can cause damage to any interconnected circuitry. Pulling or disconnecting the battery will indeed reset ECU codes on most vehicles, but that is a non-issue when repairing a properly diagnosed problem. Additionally, when changing sensors directly related to engine/fuel/spark control, it is always a good idea to disconnect the battery and/or reset the ECU in order to restore any learned data such as fuel trims to factory zero settings, in order to allow the vehicle to adapt to the new sensor(s).
Thanks for watching!
coolant leaked out of that thermostat inlet...
Too much talking
Yes it is a stupid design. Same thing with the rear spark plugs.
Indeed. Thanks for watching!
These engine design are stupid omg
Definitely not the easiest to service. Thanks for watching!
Another stupid video not explaini g wich socket used to temove the coolant sensor
Toyota is not built in Japan it's built in Georgetown Kentucky and has been since 1980 something I'm just saying this because unless you got your car from Japan it was made in America all Toyotas come from tmmk stands for Toyota Motor Manufacturing Kentucky hey you all learned something today
You're absolutely mistaken - any Toyota with a VIN beginning with "J" was built in Japan. Current Japan-made offerings have slimmed down quite substantially since the 90s/early 2000s, but both the 4Runner and Land Cruiser are built in Japan to this day, for example, and have never been built/constructed in the US. This generation Camry was built in both Japan as well as Georgetown for the US market - the one featured in this video was built in Toyota, Aichi, Japan (Toyota's Tsutsumi factory).
