Best Procedure For Flushing 13bt Coolant?

[Greg_B]

what is the measurement from top to bottom?

3" on both...

Your broken stat will be stretched beyond new. What temp is stamped on it?

It is 88 degrees celcius on the original. I still have my doubts that the original streched a half an inch.

Does anyone know the part number for the o-ring that goes around the thermostat? I reused the original when I changed the thermo a couple years ago but now that I'm doing all the cooling system work I took off the housing and the o-ring is split. Toyota does not have a listing for it as a part and it does not come in the box with a new thermo. Is the o-ring not needed??

I did not see one when I changed mine. Was the one that you pulled out the same size as the new one? I am very curious.

The thermo you mean? I was the same size when I replaced it a couple years ago. Gonna check Lordco as they list a universal rubber o-ring.
