96 b18c1 block... what goes in this threaded hole? ive been triing to figure it out for quite some time (2 weeks)!!



thanks, doug

 

On OBD1 blocks that come factory with the oil cooler, a coolant fitting would thread into that hole and a coolant hose would connect from the oil cooler to that coolant fitting. I'd remove that oil cooler, and install a oil filter holder part number 15 below and plug that hole up with a pipe plug, just like a stock 1996 GSR block, since you don't have the proper water pump coolant tube to use the oil cooler anyways.

If you do decide to use that oil cooler you'll need part #1 below, which is the coolant fitting, part #2 & 3, the coolant hoses, and

and Part # 9 and 16, the coolant tube and o-rings
