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. |

An expansion tank and overflow tank are different things. The expansion tank is pressurized and should be the highest point in your system, usually above the thermostat. The radiator cap is on this tank and it opens to purge out trapped air and coolant to the recovery tank.
I use a Dendenbear remote pump and water header like shown in the picture above. I don't know about the pump you are using but it should be probably be bench tested to make sure there's no interference with the impeller. With these electric pumps it's recommended not to use any teflon thread tape and also be careful that excess Permatex or sealants do not get into the impeller that could jam it up. |

My expansion tank (VW Passat unit with pressure cap) is mounted above the T-stat. Pressure cap is new. Please note picture with descriptions as to which ports on the expansion tank go to where. I am pretty sure it is plumbed correctly. Not sure about the 90 degree elbows used for clearance and so rubber hoses will not kink. Does the Dendenbear unit allow for coolant bypass when cold? Mine is a Renegade kit, therefore it has two separate ports and hoses going to those inlets. I see... mount the pump in the housing and rotate to check for metal to metal sounds etc... |
