Im in the process of putting a 96 LT1 into a 95 S10. I need to know what way the coolant flows to and from the waterpump. Other that the 2 major upper radiator hoses on the top, there are 3 holes. One is on the top pass. side by the thermostat, another is on the lower pass and the last is on the lower driver side. All i need to know is what direction the flow is at these three openings. Thanks.

 

Check Shoebox's site...do a search for him...all his post have a link to his site...it should be there...I think 2 are for the heater...check.He has some great info there...mark it a favorite..

 

I am using the upper port as a pressure port for the heater core. The other two are returns. I have the lower ones capped since my radiator has a heater return. I have been running mine this way for 4 years. No overheating and the heater works fine.
