DIY - Thermostat

DIY - Thermostat

The most difficult DIY eva!

1. Make sure your engine is cold. Remove your radiator cap. This will releave air pressure in radiator system.


2. Drain out your radiator fluid


action shot


3. Find the your throttle/cruise cable box and remove it



4. Remove the top portion of your lower radiator hose


5. Remove the 3 bolts holding in the thermostat housing.


6. go ahead and pull it out your thermostat now.



7. Install the black gasket as shown (mine was wrong )




8. When you re-install it, remember to place the black gasket in the housing correctly. There is a pattern.



9. Reinstall in reverse order. bleed the system and check for leaks

Estimated time: 10minutes

Note*** There is a ground wire attached to the thermostat housing. If you fail to reconnect it, the engine will not start.

A couple of things:
1) Removing the cap does not remove air pressure since there shouldn't be any air in the system to begin with. Also, the system should have no pressure on it when cold. Pressure only develops as the coolant gets hot and expands.

2) No reason to even consider changing the thermostat unless you're having overheating problems, the car never warms up or the housing gasket leaks.

Otherwise, a very nice write-up. Pictures really are worth a thousand words.

Just replaced my "stuck open" thermo last weekend, took me about 30 mins. from start to finish. Make sure the "up" mark is lined up with the bump on the gasket. That's how my OEM thermostat was when I removed it.

Also, I didn't remove the upper hose from the thermo housing, I left it clamped on and proceeded to remove the housing with the hose still attached to it.

Great DIY!

Did you drain your coolant?

Interesting. They just switched over to a new part, number 19301-P8E-A10. I just got it in Friday, and changed it today.

And I did it like Kenso, and didn't remove the hose, only the housing. And I didn't drain the coolant, either. That'll be next week when I pick it up tomorrow.

19301-P8E-A10 This is good for CL MDX RL TL, not for the legend. Check this out:
