I have a 88 3.7 470 (i know i know lol) anyways when i sent it into the back of the barn 4 the winter i drained the heat exchanger and believe i pulled 2 screws, one for the the fresh water and one 4 the 5o/50 coolant? Any one know witch is witch? the reason i ask is im going to go brown trout fishing and want to drain the fresh water and not the coolant from the engine cause are night are still going below freezing

Re: Cant remember

Actually they are both on the bottom. The one you want (freshwater) is furthest aft. Download (takes a while) the manual in the adults only section, look under #9 manuals, service manual #8, cooling section. Good luck fishing.
