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. |

I never thought the restrictor washer was necessary. I understand the thinking behind it, such as raise the pressure on the line to the radiator to either prevent steam bubbles or reduce the flow so the radiator has more time to cool. Some of this is based on old fixes going back to the 1950s.
I'd make sure you have all the air out of the radiator and hoses at the front. This means having a bleeder petcock at top of rad you can open when you are filling the system. Also check that you don't have excessive hot air recirculation. With the inner wheelhouse openings there will be some recirculaton to the front of the radiator. I'm assuming you already have good shrouding around the radiator. One way to check recirculaton is to measure the inlet temp with the engine idling and fans running, and hood closed. Then open the hood and see how much of a temp drop you have, with the radiator heat allowed to exit up where it really wants to go. If this is more then 10 degrees then you might want to look at how the air is recirculating and block it with a spoiler or air dam under the car. If you have a new radiator why are you doing a flush? Do you think the block has a lot of rust in it? If it does that can clog up a new radiator pretty fast. Check the water you flush out to see if it has a lot of rust particles in it. Good luck with this. Hope you find the problem. |
