Tough question, probably tough one to answer. I've been trying to get my engine to run a little cooler. Everything has been checked or replaced.....except the water pump. It's the original pump that came with the motor in 55, just wondering if there's a way to check flow or pressure. I mentioned in an earlier post that running the heater helps knock 10 degrees off the top but when it's 90 out the heater isn't cool....no pun intended. There were suggestions that might be the radiator, but it was spotless, the guy at the shop didn't even rod it out. Thanx, Gary
