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. |

You where saying decent temps of 180-200. You then said creeping up past 200.
Does it stop there or did you just stop. My V8 914 in 78 went to 200 a lot. I also owned a 85 corvette in 94 that the heat went past 220 and I just did not want to stop and I was in the desert and had 2 miles to go and I said screw it and overheated it and blew a head gasket. No water got in the Eng. One of my guys put a new head gasket in it and it was fine. So how hot has your car got? Bob B |

I do not think my car has ever overheated (with the engine in the 914 anyway... previous owner... possibly). The gauge continues to read even after the engine is shut down. I have seen the temp creep up past 220 like this. I have also seen the coolant bubble (boil?) in the overflow tank once or twice... cannot recall what the temp was reading at the time but I am sure it was up there. I am going to rent a pressure tester tomorrow and see what happens. I would like to rent a leak down tester but it seems that no one around here rents one! |

I have also seen the coolant bubble (boil?) in the overflow tank once or twice... cannot recall what the temp was reading at the time but I am sure it was up there. Temp creep isn't uncommon, as the heat rises up to the temp sender. Coolant bubbling is common when there is air still trapped in the system. Update... I went and rented a pressure tester. When I got home, I removed the cap from the Crown Vic expansion tank and immediately noticed that the expansion was still full of coolant. I had never experienced that with the Passat expansion tank... that tank was always half empty... no matter how many times I filled it before driving... always. This doesn't surprise me. My engine in it's original car has a 9 quart cooling system. In my 914 it's 12 with the 20ft of 1 1/4" hose. Since the Passat tank was designed for a little 2.0 or 3.0 engine with 1-2ft hoses it's likely expanding beyond capacity. |
