Hey guys!

I'm doing a custom Ecotec Turbo install on a Pontiac Fiero, and I have a question reguarding which pipe does what. I think it does flow into the block first, but I'd rather double-check.

In the pic below, does coolant flow into the pipe on the block (big pipe on the right), through the heater core pipes (the two pipes sticking up), and then out the pipe on the cylinder head, or is it the other way around?

If it is as described, that would rock! Then I'd have a place to tap into for the water cooling of my turbo, cause the heater core is up front with the radiator, not in back with the engine (it's a mid-engined car).



THANK YOU!!!
