Yeah, I've got one. It's Service Manual #9, same as all the V8's for that year, what are you look for?

Boatinfo has #9, it's the manual for all V8 engines 85 to 88.

You mentioned closed cooling, what exactly are you looking for. It may not even be in the manual.

Like a car, if the engine is hot, you could burn yourself with hot antifreeze when taking the heat exchanger cap off. So be careful
