It's attached with bolts.Yes, with the right fan clutch being used. Is your current fan clutch attached to the water pump with 4 bolts or is it a thread on?

Ordered a new Genuine GM thermostat from RA. It'll be here Thursday.
Actually, it's GM Genuine. Should work.I didn't know that was a thing.
TBI may be different. My '97 K2500 7.4L has two knock sensors in blind holes, very near the two block drain plugs in pipe-thread holes leading to the water jacket.454 has 2 knock sensors for block plugs.
Agreed. The primary cooling fan on my '92 and '93 Luminas don't come on until 220F. The secondary cooling fan doesn't engage until 230F.220 is nothing for the engine.

I put brass draincocks into the block drain holes. Makes things easier the second time you want to drain the block.
Thanks for the photos. I would expect the '96 and '97 are similar in that regard.Right side of engine block, near knock sensor. Optical illusion due to camera angle: draincock appears to be pointing "up" when it's actually level or somewhat downward.

The engine is not in distress until the coolant boils, assuming that the high temperature doesn't produce detonation. If boiling or detonating, it's in REAL trouble.
Indeed, to best of my knowledge, the TBI 7.4L only has one knock sensor in passenger head.TBI may be different

Loctite/Permatex 592. Anaerobic sealer, doesn't just evaporate solvent out, it hardens like thread locker. (but not so secure that the parts can't be removed. In fact, the sealer also prevents galling of the threads. Miracle stuff. There are several formulations of what are essentially similar products--565, 567, some others, and a chapstick-looking semi-solid which might be 504.do you use teflon thread tape, pipe dope, or something else to seal the threads?
