This appears to be the thermostat gasket. The OP is looking for the O-ring where the lower rad-hose extension-tube connects to the thermostat inlet-housing.Stant 25286, $0.43 closeout on rockauto.com. Or find Fel-Pro 35654 at parts stores for about $1.50 (http://www.rockauto.com/catalog/moreinfo.php?pk=447039&cc=1364622). I prefer Fel-Pro seals and gaskets.
So to change out the 'Stat, you need the thermostat gasket, and the O-ring right? that's it. Or are there two O-rings?
Thanks! Good to know. The Felpro should also suffice right? So how common is it for these to "give out"? I mean what happens to them that they just give way like that? Is it the coolant? Is it defective manufacturing materials? Sorry but I am not a mechanic, but I'm not a dumb arse either an I want to gather as much info about these failings as I can to help me understand what's going on with these parts. I assume the same thing could happen to any O-ring in the cooling system or the Oil system for that matter correct? I know that it's probably a good idea to change out any and all O-rings one will encounter in any type of job such as a thermostat change while you are in there just to freshen things up a bit. I know some of these questions have some of you mechanics rolling your eyes. However please realize that not all of us out here possess your gift so please bear with those of us who are ignorant to the automotive arts. Now ask me anything computer related and I'll be able to hold my own. :rockon: My hope is that somebody with the exact same problem will one day read these threads and know what to do next as a result.
WHAT? The Toyota dealer list price for this part is $3.68. Many Toyota parts centers sell if for about $2.70, especially if they discount prices for vehicles having over 100,000 miles on them (many do). This dealer ripped you off. At least we are talking a very, very low cost item here. Wouldn't buy a $100 part for that dealer though.The online price from the dealer was about $2.65 for the o-ring, but when I showed up at the dealer, they charged $6.70 for it.
This is for hypermikem, I said I would post photos for you. I replaced my 2000 avalon radiator but i have photos of the inlet pipe and the o-rings for the thermostat and the inlet pipe. You'll see the photos if you scroll down on the thread. Camrys and Avalons share this same part.My hope is that somebody with the exact same problem will one day read these threads and know what to do next as a result.
