My thermostat housing gasket is leaking a fair bit and I would like to replace it. Nobody here carries or can order a gasket for it. I know TA Performance has then but ordering such a small, inexpensive part can easily spiral out of control with international shipping, duty, etc. Can I just cut one out of gasket paper or does it have to have some special material? Anything else I need to know? jeremy
I have used gasket material to cut out my own water pump gasket for my 455 and had it work out fine so I would think it will work for a thermostat housing gasket. Maybe someone more knowledgeable will chime in. Cliff
It's installed and going for a test drive later this afternoon. I was surprised there was to torque specification listed in the manual, since there was for just about everything else.
When a thermostat housing gasket has been leaking for awhile the antifreeze corrodes the aluminum on the gasket sealing surface as well as the neck of the housing where the upper rad hose attaches. Depending how badly the neck is corroded you can clean the neck up very well, wire brush, etc. Mix up some JB Weld & fill the pitting. When dry sand it down so the hose will conform. On the gasket sealing surface you can mount the housing in a Lathe & remove material as nec. to have a flat surface. Not too much can be taken off as this will make the "Flange" too thin. If you end up with small pits, again, you can fill them with JB Weld & sand flat on a hard flat surface. Or you can buy a new billet aluminum one from Russ Martin.
