ok, working on the same area, now the water outlet/thermostat housing. I got a better one for the engine with gasket and new bolts. Do you guys recommend to put a little of the thread lock on it or just leave and torque to specs?
I have some of the blue permatex, will that be OK. aiming for this weekend to take it for a spin again. what do you guys recommend to put on the water outlet gasket?
Permatex http://www.permatex.com/products-2/product-categories/gasketing/gasket-makers/permatex-water-pump-thermostat-rtv-silicone-gasket-detail Make sure the thermostat is seated and not pinched under the housing ear, this happens many times and leads to a crack in the ear and a leak, seen (and done!) a few. Napa sells stick-on gaskets that hold the stat in place and only need a sealer on the top. Read your manual and use a torque wrench, its 25-28 ft-lb on GM's, should be about the same on a FoMoCo, very easy to overtighten and strip or break the ear off the neck. But you know that....
