Yes it's the two bolts per housing,two on the left housing and two on the right housing that hold the thermostats . The right bolt on the left housing the treads ( not on the bolt ,the treads that the bolt screw into ) are stripped. But they don't have lock washers,never did . I did it, I didn't know that the housing has one side of it is thicker that the other side so when I installed the bolt it wouldn't go all the way in and I put to much pressure on the bolt. Stripping it. When I removed the housing to clean them out I must have put the left one in backwards. The only good thing is that I did it, a lesson learned. I'm tired of learning my lessons , I just want to fish. It's a 1/2 inch bolt
