273 Overheating

Check the plugs to make sure your fuel mixture is ok a too rich or too lean mixture could cause an overheating problem.

As for the water flowing too fast through the radiator, I don't believe in that either.

And remember the thermostat's job is to keep your engine from running too cool, the radiator's job is to keep it from running too hot.

I have every cooling device known to mankind on my car. 26" aluminium rad, Brass Works HP water pump, transmission goes through a separate cooler ( not connected to the rad at all), engine oil cooler, 7 blade mechanical fan and a electric pusher fan and STILL it ran hot. I found that not having a seal on the hood to radiator support infected the cooling dramatically when idling with the fiberglass hood on. The biggest improvement cooling was when I installed a air/fuel radio gauge and got my fuel mixture dialed in. What an improvement! Runs better and is 10 degrees cooler in traffic. Good Luck
