Whats the best way to install a mechanical water temp. gauge?
 

I bought a Equus 7232 and am having trouble figuring out the best way to install it on my 1988 4.9L engine.

I found the plug in the block where the plug is now (under #6 exhaust man.)

If I take that out, can I get the right size reducer installed to where everything will seal up tight? The gauge is 5/8-18 and the original probe-nut is 11/16.

Also, I pulled the lower hose off the water pump and got about 2+ gallons out, if I get the plug out will a bunch more coolant come crashing down all over me?

Well anyways Ill update.

I went back to the auto parts store and talked to someone else and figured out they sell a whole kit with adapters they didnt tell me about the first time which made it possible. Much easier to figure out a puzzle when you have all the pieces.

Went to a friends because he has better sheet metal working tools than I do, and thought you all would appreciate a good looking collection of F150's. A 12th gen, two 10th gens, and my 8th gen. :)
