RE: overheating in my '59 Galaxie |

Head gaskets is a good thought, but that would cause rear-engine overheating while keeping the temperature indicator looking cold. Is the gauge reading hot during the overheating, or is the engine simply misbehaving?
I've often been in the situation where the belt slips in the pulley groove, causing the motor to run hot. Replacing the belt and pulley may be a solution, but I've typically only replaced the belt, and improvement wasn't always what I got.
Going to a double-groove pulley solved the overheating completely whenever I did it. I wonder if the later pump, with the larger impeller, is subject to more belt slippage, due to the greater force which would be required to spin it? Hmm...I've never really nailed the details, but haphazardly settled on double-belts to eliminate overheating problems.
As my next build will be a 427 fanless experiment (elect fan/alum radiator), I'm going to use a double-grooved damper to drive the double-grooved water pump pulley and alternator. Hopefully, it'll be a simple robust set-up that runs cool.
If the timing isn't way off, then maybe a small-impeller pump or twin belts is a solution.
