Hey all,
Inching closer to going electric on my V8 conversion car. Right now; going through the process of cleaning out radiator and water passages/block with ThermoCure, then Prestone citric acid flush. Assuming I get a really clean system but not fix the run hot situation; I will go electric. Where is the best place to mount the electric pump? It would seem that the easiest way to go in my case is with this: http://www.jegs.com/i/JEGS-Performance-Pro.../50930/10002/-1 It a 50 GPM unit that should bolt right up to the Renegade remote water pump housing already in place in my car on the lower left hand side of the engine... that is assuming there is enough clearance between the water pump and the firewall. Would this work? I have heard stories going back and forth about mounting the pump by the radiator or by the engine. |

It looks like it is essentially in parallel with the radiator. The unknown is how much coolant is bypassed through the tank. Obviously it has been designed to work in the Passat 6-cylinder application but is this good in a 914 Chevy V8 conversion where you need as much cooling capacity as possible? I'm not saying this won't work, and maybe it's been used in other 914 conversions successfully. What I am saying is this tank is a different setup then the usual small block Chevy cooling system. To me it would be unnecessary to have the line going back to the suction side of the pump. Maybe you could clamp this line off and see how it affects the cooling? |

Thats the whole purpose of this expansion tank. Its constantly purging the coolant. Air bubbles and coolant flow into the tank from the small line, then coolant only returns back into the system. |
