If it's just the thermostat housing, remove the hosing, and make sure the themostat isnt stuck under it, there is a groove the t-stat sits in some are on the block, others are in the housing, when you tighten it, just snug + a little! It's easy to crack these!
Get a new t-stat while youre at it. Hope this answers your PM! And scrape ALL the old gasket and replace with a new one.
