Thermostat change.
Hi Guys,
Well I posted a couple days ago about wich thermostat to use for my truck and now I have a new problem. When I purchased the new thermostat they had a gasket and also a liquid gasket hanging beside the thermostats on th wall. When I checked my manual it just said replace gasket and I'm not sure to use a "conventional" gasket or a liquid gasket or both. What do you recommend?
Thanks,
Evs

I always twist-lock the thermo into the housing, then use a high-tack sealant to glue the paper gasket on the housing, let it set for a while (1/2hr to an hour), then re-assemble. Nothing falls out of place while you're trying to finagle it back in, then.

It all depends on what I'm doing. Non-critical stuff, I just go by feel--"snug", if you will. I usually hold the ratchet with the center of the head in the center of my hand, that keeps me from over-tightening things. Something small like a thermo housing doesn't need a whole lot of torque to hold it on, and the two bolts are pretty close compared to the thickness of the gasket, so as long as they're just snug, that's good enough. I've often found that the torques listed in books can be too low on some things--exhaust manifolds, tranny and oil pans, to name a few. IMO, if I can still turn it with my oily fingers at the listed torque, it's not tight enough. And, yes, I've learned the hard way on a few things what too much torque is...
