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. |

The most common is probably one similar to this. The small fitting fits a hose going to your overflow tank.
(IMG:http://www.rickwrench.com/images-sounds/filler.jpg) Renegade makes one that looks nice. This would have to connect into your system with a tee and be mounted high in the engine bay. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.renegadehybrids.com-2923-1493926666.1.jpg) I use a modified Dedenbear tank that bolts onto the intake manifold over the thermostat. It has a lot of volume but it can be a little awkward to fill. I just use a long funnel and it's something I only need to do every few years. Are you sure the cap on your Passat tank is a pressure cap and not simply a fill cap? Is there a pressure rating on it? Having never seen one I don't know anything about that. Edit: Here's a used Dedenbear tank with an AN fitting. This one is on ebay for $75. These tanks have a section of clear nylon tubing so you can visually check the coolant level in the system. Mine had that but the tubing discolored after a few years and I plugged the holes. To clear the firewall on mine I cut off the hose connection and tapped the hole to thread in a 90 deg fitting.
