I have a 2004 Tacoma truck with 158,000 miles that runs perfectly, but I'm sure it's likely running the original thermostat. I'm contemplating changing my thermostat just for maintenance reasons - is this a smart idea? If so, I'll change the coolant as well, of course.
I guess I'm "old school" in that I typically think most gaskets and/or surfaces should have a sealant of some type to really be assured of not leaking. In my case, my thermostat "gasket" looks like a rubber o-ring from the picture - http://www.oreillyauto.com/site/c/detail/FEL0/35445.oap?pt=C0420&ppt=C0331 but I'm still wondering if it's a good idea to use some form of sealant between the water inlet housing and the block? If so, can you give me a recommendation for a sealant?
Thank you,
Ed
