Skip Haney's water pumps work- Real world traffic experience

I had to change the generator on my hot rod. I wanted to make sure the new one was all OK, so I did not re-install the generator mounted fan for the test ride. I was being lazy and didn't want to have to take the fan off the generator again in case it needed to come out again.

Today, it was 88 degrees in NJ. While testing the car, I went down the main drag and got stuck in traffic. While idling, the car got to 195 degrees and held steady.

Once out of the traffic, I decided to pull over and let the engine idle to see what would happen to the temperature. Actual idling time was 10 minutes and the temp never got above 195.

Again, this was without the fan installed.

The system does have a Walker radiator and the block was surgically cleaned and all the crud from the water jackets was removed before the rebuild. I'm running straight water.

That said, the flathead is a 292, so it is a big cubic inch engine.

Once I started moving again, the temp dropped back down to +/-175 degree range.

I'm convinced Skip's pumps add to the overall cooling system to help keep the motor within an acceptable temperature.

If the fan belt was off of the car, The water pumps weren't pumping, and made no difference a tall. I don't care whose pumps you were running. My 2¢

Larson,

I think you misread my post. Only the fan was not mounted on to the generator pulley, but the fan belt was on and pumps were fully functional. I run a one belt set up.
