When I removed the old thermostat, the gasket stayed in place and I had to pick it out of the shoulder. No big deal. The new thermostat and gasket were bagged together loosely. So I loaded in the gasket and then followed it with the thermostat and cover. What I didn't realize (and this video quickly passes over it) is that the thermostat is designed to ride inside the o-ring, which has a slit all the way around to capture the thermostat and center it properly on the shoulder of the block. So after almost 2 gallons immediately leaked out of the block, I regrouped and re-watched the video, stopping it several times until it dawned on me how the new thermostat is supposed to fit. Maybe this comment will help someone else.
Glad you were able to find my video Luke! Thank you for watching, and thanks for the nice comment. Hope you were able to get your thermostat changed out without too much trouble. Take care, Dan the Fix it Man
Thanks for posting. I'm considering flushing my radiator and usually don't remove the thermostat. After watching your video, I think I might remove thermostat and don't that way
Testing result is for curiosity. But you don't want to find out the truth while in a remote area or on a highway. Just replace it as scheduled. You won't fill the gas when the tank is completely empty. Same point as scheduled maintenance.
Thank you for this video...DUH...Im such a NOVICE....I had to remove the Air intake...and disonnect the electrical wires...And had to work from the top....Why didnt I think of removing the battery for such easy access?????.......Thankx again....
Same here. The coolant keeps backing up into the overflow tank too so it starts to overheat... These 3.5 engines suck with vcm management. Eco mode just causes problems. Seems intentional to me. More problems, more money for the auto makers..
I ordered a thermostat, gasket and 2 gallons of honda blue coolant. How much coolant will I replace draining the radiator, reservoir, and replacing the stat?
ruclips.net/video/xHmmXqMAVbQ/видео.html in this link it doesn't look like much coolant is needed after the drain bro. but i got 2 Honda coolant on the way also with the thermostat and gasket, its a good diy video.
You make it look so easy to do, but I'm disabled and I can't find out why after I filled the radiator with the right fluid shouldn't I get heat right away. My dashboard gage keeps going up and down and after about 20 minutes the heat finally kicks in???.
Hi John, It might still have air in the system that needs to bleed out. Sometimes it helps to squeeze the radiator hoses a few times. If you haven’t replaced the thermostat yet, and the gauge jumps around, it could be a sticking thermostat. If you already changed it, then it’s probably still air in the system. Best of luck to you!

Very nice and easy to understand the process. I exchanged it 2009 odyssey yesterday but my radiator fan didnt work. Fan moter worked and upper radiator hose was very hot but fan didnt work. Do I need to open thermostat again? Thanks in advance!!
It varies, I have seen some OEM ones last 10 years and over 200k miles. The thermostat is just a thermal-mechanical device and does have a finite service life. They do and can become slow (lazy) or sticky (binding up as they try to open or close) as they get older, and when they fail, they usually either fail open or completely closed. I would just change it if you are not sure when it was changed last. They are pretty inexpensive and it's not a hard job at all. Some recommend changing them at the same interval you might change the belts and hoses. Thanks for watching! -Dan the Fix it Man
It was running hotter than normal, especially at idle or in slow moving traffic. Replacing it completely solved the problem. Thanks for watching! -Dan the Fix it Man
Also if the fan comes on after you shut off the engine, and it does this no matter the weather or driving conditions, the block is getting warmer than normal and it is likely the thermostat.
I found using a deep wall socket, followed by a universal joint, followed by two handle extensions and a ratchet, I could operate the ratchet handle as it extended into the battery compartment tray. You're right, it's not easy, but I found this wrench combo took some of the frustration out of it.
Why is there always someone that dislikes videos of someone trying to help others... You don't like people helping others or are you guys just never satisfied? Either way, don't watch it if you dont like it.
Sorry I had to thumbs down because you supported the scam artists at honda charging $90 for a freakin thermostat. also you dont need to take off the hose.
Great video. To the point instructions without the annoying comments and BS that many people will have on their videos.
For real, like they have no friends.
Thank you. I have to do this on my ‘07 Odyssey, not as bad as I thought.

@@steveloux4709 thank you for pointing that out, sorry for not showing that in more detail.
Take care,
Dan
finally a decent video, thanks!!! tired of having to dig through pages for this stuff, youtube always prioritizes the SHIT diy videos.
Glad you were able to find my video Luke!

Thank you for this video. It's very helpful.
thanks !! your video saved me a lot of time....as I thought I had to take out the wire harness
No Problem Tim,
Thanks for watching!

THX - prolly will change upper and lower hoses as well (and the rad cap). Thx for posting this.
Thanks for posting. I'm considering flushing my radiator and usually don't remove the thermostat. After watching your video, I think I might remove thermostat and don't that way
That’s a good point about testing the thermostat in boiling water so you know if it was bad or not.
@wrxassa to see if the thermostat was actually bad or not....

That looks so easy!! Thanks!!
Thank u you made it easy for me
Great video need a little wider shot of what you were doing and where it was at, over all nice!

Thinking about doing replacing mine because the temp gauge is fluctuating
Same here. The coolant keeps backing up into the overflow tank too so it starts to overheat... These 3.5 engines suck with vcm management. Eco mode just causes problems. Seems intentional to me. More problems, more money for the auto makers..
Help dropped the bolt to the ground wire. Bolt on middle top of thermostat housing. Where can I get a replacement? 2009 Honda Odyssey
very good
On mine the harness is in the way of the back bolt. I can’t move the harness out of the way.
Isn't the jiggler tab supposed to me at the top to let air release correctly? Air in the lines creates big issues - I know.
I ordered a thermostat, gasket and 2 gallons of honda blue coolant. How much coolant will I replace draining the radiator, reservoir, and replacing the stat?

Why drain coolant ? It’s only gonna let out what’s in hose
You the man stan !!!!
Well, thanks. I did it, but I don’t have long sockets. That was a serious pain in the ass.

You didn’t need any gasket maker to seal the leak?
Great video! What brand of fluid do you recommend?
Hi Tom,
I used Zerex Asian Vehicle Blue Premix 50/50.
Thanks for watching!

Nice thanks brother !!!! Like 👌
Very nice and easy to understand the process. I exchanged it 2009 odyssey yesterday but my radiator fan didnt work. Fan moter worked and upper radiator hose was very hot but fan didnt work. Do I need to open thermostat again? Thanks in advance!!
In my 2002 Odyssey, I checked both fans by connecting the terminals to the battery. I used Hanes manual.
How many miles need to replace thermostat

How to know that your vehicle thermostat is gone. If is Ok thn you can do something els
will this be about the same for a 1999 model?
What were the symptoms of the bad thermostat?
It was running hotter than normal, especially at idle or in slow moving traffic. Replacing it completely solved the problem.

Dan what happens if you dont drain the radiator?
Coolant will drain from the thermostat housing.
Subbed!
No matter how hard I try I can’t get that second bolt out. It’s so frustrating
You might try some PB Blaster penetrating oil on it if it’s being stubborn. Hopefully you can get it without breaking the bolt.
Best of luck to you

I liked the video but I see your point.
I suppose, but it is a LOT easier with the hose out of the way.
