    I am replacing the thermostat and was wondering if the paper gasket is good enough to seal the housings? Should I use some other type of sealant?

    Thanks

    I use a light coat of silicone on both sides of the housing gasket.

    Do you have the seal for the top of the stat to the housing? Should be a black rubber(hard now) ring.

    I also use anti-seeze on the bolts to prevent them from corroding and becoming one with the housing through dissimilar metal corrosion, and I usually put in new bolts too, but if yours are in good condition and not detierorated, you should be fine.

    Good luck!

    Those bolts are the crappiest bolts Toyota makes-I have snapped 2, and I am very careful about stff like that.. I do what Poser does-a very thin layer of RTV-gray-on the housing gasket and antiseize the bolts. If you like having heat- make sure you install that upper gasket on the top of the thermostat. One other thing-Use Toyota gaskets-NAPA sells a set, but the housing gasket is too thick to work properly.

    Sounds like a good time to replace those bolts. I should've done that when I was into it 3 weeks ago. Hmm, I guess I still could.... one at a time.

    Just curious, but does anyone know if they make a chrome thermostat housing for a 1F engine?

    No, but I am sure you can have your aluminum one chromed for a small fee.

    They do and it is the coolest thing. It brightenes up the entire engine compartment. There are chrome valve covers also. I really like them. You can also get some of the fake briaded lines for it. Man, that would be cool once you ge tit done. There is a chrome timing chain cover that is SO bling. You should have it or you aint s***.
