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. |

If you can measure the air temp in front of the radiator you can get some idea of how much hot air is being recirculated from the wheelwells at idle and when the car is not moving. There will always be some amount hot air get pulled back into the front depending on how you made your radiator inlet openings. If all your air is through the front with the front bumper cut out, it should be less of an issue then if you have openings in forward part of the trunk floor. If enough air recirculates it can cause your engine temperatures to creep up when the car is not moving, and you can never get the temp to stabilize. There can be other cooling system problems that can cause this to happen also.
So if you can monitor the air temp in front of the radiator, then open the hood and see if the temp drops quickly (close to ambient) that's a good sign that there's some recirculation going on. If there's not much drop, just a few degrees, then you don't have a problem. Since hot air rises the radiator heat is going to escape upward quickly with the hood open. With the hood closed it is forced out around the front wheels and it has to find its way out around the fenders. There's more turbulence going on and some of it can get sucked back into the radiator depending on the layout. So this is just a quick check to either see if this is a concern or rule it out as a non-issue. |
