How to replace a thermostat on a 2001 toyota sienna 

Excellent video. I've done a few thermostats before and figured this would be a 10 minute job, but when I went to look for it I couldn't find it. Thanks to your video I have more confidence in changing the thermostat tomorrow. Thanks from Mike in Oregon

Agree, excellent video!

Great video.

Thank you for this great video. I need to replace my radiator on the same car. But I will be replacing the thermostats with a new one for sure. Just feel that's the best way to go. Again TY.

Outstanding video and level of detail. Really appreciate you taking the time to set up the camera angle for a better view.

Thanks for making the video, replacing mine soon

Excellent video..!!! Thanks for sharing. Great job.

Thank you very much for this! I used your video to work on my mom’s Avalon. It’s basically the same process.

Thank you for posting

ty best video i found

I would consider that to be bad because the thermostat opened slowly it should pop open fast i had a car that i tested the thermostat and it opened i visually saw it open but it opened kinda lightly well that ended up not letting the hot water pass when it needed it to which made the coolant boil over and it wouldn't show on the temp gauge on that car but it damaged the car cause i had to drive it home but i did what I had to do but the thermostat is a inexpensive part you should just replace if you think it needs replacing just do it. Don't take it apart to look at just replace the thing

I just change mine to new thermostat than broke the head on one of the bolt after i tightening it😬

very detail, thanks a lot

My 2001 sienna still showing over heating while driving but go back to normal temperature on idle. Any idea whats the problem?

Hi I have a couple of questions if you could kindly answer. First why did you add coolant through the hose and also by removing the cap. ? I mean shouldn't just filling up the coolant reservoir be enough to pull the coolant through the engine and the radiator? Second I replaced my radiator because it had a leak. I filled up the coolant reservoir but id not pull the coolant to the radiator when I turned on the engine. Basically no flow of coolant. The engine started overheating. Any idea what the problem is.

What program are you using? Where it shows the diagram and where the bolts are?

Why would you put coolant through the hose instead of the coolant cap at the engine? Or it doesn't flow to the radiator on its own?

thanks for the video... but if I go all the way to removing the thermostat i'm throwing it away and putting a new one. They are like $12, for all you know it could be ready to quit in the next 10,000 miles, anyway. One time i had one jam shut and I admit an idiot, didn't notice and it blew a hole in a piston when it overheated... just change it and forget testing them

Man your wife is gonna have a fit dropping that thermostat in a stainless stell sink . Lol . Great video tho

Por favor en español. Mi Guagua pierde potencia, Que hago

My 03 highlander with same engine isn’t over heating but it’s midway, when I drive it goes down a bit below midway I’m at 99k miles and my mines aren’t turning on

But who am i . I cant even spell steel correctly. Lol☺

I don't think what's the hell he doing.
