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. |

On what you call a two-port expansion tank, one side of it is pressurized and connected into the cooling system. The other port is after the pressure cap so that as the coolant expands it goes past the cap and into the non-pressurized overflow tank. These tanks typically connect high in the system and above the thermostat in the intake manifold. This allows any air to get purged out into the overflow tank, then as the engine cools down only coolant is allowed back into the system. So air is automatically purged out during heating and cooling cycles.
I've wondered how the Passat tank is designed. If it connects to both the suction side of the water pump and after the thermostat (hose going to radiator) then what prevents coolant from bypassing the radiator and flowing through the tank? Is this how it is connected in a Passat? Is there something inside the tank that prevents bypassing the radiator? |
