Hello! I have a '71 Mav, with a 200 engine. Prior to putting in a new radiator, I decided to replace the thermostat (from Motorcraft). Then the thought occurred, if I'm replacing the thermostat, I ought to replace the 44 year-old bolts to it. I'll make sure that the new bolts have the three lines on the bolt head. My question is what torque number am I to tighten them? Also, from the local auto parts store, I got a gasket that has an adhesive backing. Should I use this along with the brush-on gasket compound? Thanks for the advice!
