I replaced the thermostat on my 93 Crown Vic yesterday. I had a hard time getting the 2 bolts loose, either someone put them in wayyy too tight when it was last changed, or they corroded into place. When I finally got both bolts loose and hauled 'em out, I noticed what looked like grainy sand on the threads of one bolt. In goes the new t-stat, and I attempted to reattach the t-stat housing. Well, it appears I did something wrong, the bolts were going in way too tight so I got my brother to help me out. He took the bolts back out, and one of them had aluminum flakes on the threads! Not a good sign ya know. He tried to tighten the bolts back down as best he could, but he said it didn't feel like they were tightening properly, the threads inside the bottom part of the t-stat housing were probably stripped. He did get them tighened down, then I took the car out for a short drive to warm it up and check for leaks. My temp gauge still moves up and down and when I came back I didn't see any leaks. Today, I opened the hood, and the area around the t-stat housing is wet! Dang it to heck! What am I going to do to fix this? Would some gasket maker between the top and bottom part of the housing help any?
