: I have an instant overheating problem and I hope some of you may have some ideas on what to look for, and how to fix it..
: First, some history that may answer some of your initial questions.
: I have a truck radiator (4 rows of tubes) on my coupe.I had the top tank removed and had all the tubes rodded out.I have a B waterpump on the engine which has the larger impeller.The waterpump shaft has very little end play.
Larry,
If your gauge reads 140 idleing in the driveway or going down the road nothing is wrong with your car.If you still suspect something is wrong, check the accuracy of the gauge by placing a thermometer in the top tank and let it touch the water, when the engine is warmed up.I have a 31 coupe with the original radiator and a Rex-a-co gauge in my car.The car runs between 170-180 but the gauge shows 190-200 but, I live Phoenix, AZ!

: I have a four blade fan and a temperature gauge with the sensor on the pump.After running for about 5 minutes, the gauge reads 140 degrees, and the top of the radiator shell has condensation on the outside from the heat.
: I also had the engine totally overhauled by sleeving back to standard with new pistons, pins, valves, etc.Could a "tight" engine cause excessive heat?Can't really tell if this is so, as my coupe is 12 volt negative ground, so the starter is a little aggressive.
: The timing appears good, as the engine starts "right now", idles nice and acellerates well.I'm also using a Model B distributor that has the "flying weights" which eliminates the manual spark control.
: Your thoughts?
