Hey guys 97 Camaro Z28 m6. Just dropped a 95 LT1 into my car. The engine was last in a 60's corvette and apparently the heater outlets on the waterpump were capped off and custom outlets were installed somehow. My question, what hoses do I need to put coolant in the car? Just the upper and lower? AC compressor not hooked up so Im not worried about AC or heat for now. I just want to get it running. Thanks for your help guys.

The crucial hoses are the two fat hoses (upper and lower) and the steam line coming from the back of the heads (which connects to the radiator). Everything else is entirely optional.

 

What about the driver side bottom smaller hose that goes to the water pump? What is that for? Right now, the outlet on the waterpump that hose goes to is capped off, and I dont wanna mess it with right now unless I have to.

 

You don't need that - it went to an oil cooler if the car had one and if not it just went to the bottom of the radiator on that same side.

 

Yawp. That way GM only had to manufacture one water pump design instead of two.
