GVR4 or 1g coolant system FSM

[citymunky]

Does anybody have a copy or link for a GVR4 or 1g coolant system FSM? My old motor came with a 1990
OFH and I'm going back to a stock water cooled OFH, and with that being said I think I'm missing parts and I need to figure out what I need, and how to route the water lines.

What does FSM and OFH stand for?

Will this work?

OP: if you are using a water cooled turbo, Defiant's diagram is perfect. just follow that one, you'll be good to go!

edit: if you are using an oil cooled only turbo, you would be best off to use the '90 coolant housing. this only has one nipple for coolant (originally for just the turbo) but you could use that to feed your OFH. then, simply use a 91-94 style coolant pipe, with both the turbo's hard line, and the nipple for the OFH.

Thanks for the 1g pic Defiant.

I am missing item 43, the hard line that runs from the OFH to t-stat housing. When I removed the engine it have a long rubber hose from the t-stat housing looping under the turbo and than going to OFH.
