Question about 1988 Oldsmobile Delta 88
I have removed the one(1) bolt that holds the housing onto the block.Does it have to be rotated in order to get to the thermostat,or should it just be pryed up and out?
Wups, back up, sclatt-that housing should have two bolts (almost all do, some have three, but very seldom). The housing should pull straight off or up, wherever it's situated on the engine, exposing the thermostat, which you then remove from the engine block. Again, just lift it out. Take careful note of how everything came apart, so you can put it back right (like the gasket, parts removed, the seating of the thermostat, etc.).
Ease of access is the key to whether you have to remove or set aside anything in the way of replacing the thermostat. The housing should come right off once the retaining bolts are removed. If it's stuck with old gasket sealer or corrosion, just tap it lightly till freed. Putting it back together is where you need ease of access-you want the gasket to stay in place, the thermostat to stay in its place, the retaining bolts to be easily reached and torqued down to specs. If you don't have a torque wrench, or unable to borrow one, snug them down evenly, and then just past snug by a hair-about 20-23 ft.lbs is what I'm trying to say.
I hope this helps you. Good luck.

remove the other bolt from the thermostat housing and remove the housing. My fear at this point would be that by removing intake manifold bolts and wiggling the manifold you may have damaged the intake manifold gasket set, which is a much more indepth repair
