Overheating Issues, Perplexed

[twobjshelbys]

Here is an interesting thing. As soon as I get mine home from a drive where the gauge went hot, as soon as I got home I put my hand on both sides of the radiator and it is cool. It's doing its job.

I'm still getting a little blow by - the coke bottle had an accident on Monday - but it was over 90. The bottle is about 1/2 full and the tank at cool is also 1/2 full. I still think this is the right track.

I ordered a 160*F high flow thermostat and 22/24lb cap from Summit racing today. Should be here Thursday.

Notes on "Antifreeze"
The MAIN purpose of "Antifreeze" is to lower freezing temp, A side affect of the Propylene glycol & Ethylene glycol (the primary ingredients in "Antifreeze") is that they also raise the boiling point ( the point at which the liquid becomes a gas).

This does not mean that it (antifreeze) makes a car run cooler, it means that it increases (raises) the point at which the cooling system water will boil.

It (antifreeze) does not significantly increase or improve the "convective heat transfer" capability of water (the ability of water to exchange heat). Convective Heat Transfer is whats key in getting your car to run cooler.

Here are some links to comparitive tests of "water", "water wetters" and "antifreeze mixtures". Note the running temps recorded.
