Overheating problem solved

I have had a overheating problem every summer when setting
in traffic or at stop lights. Today I put 1 pint of Royal Purple
Purple Ice in the radiator and was simply amazed at the results . Never got hot once today ( and I drove the hell out of it all day)
Best 10 bucks I ever spent.

So how does that stuff work? I can see how anti-freeze or pressure can raise the boiling termperature but how does an additive actually make the engine run cooler? Thanks.

Decreases the suface tension of coolant thereby allowing it to transfer heat more effectively

A problem with overheating while sitting in traffic is usually a problem with the fan system, either a bad fan clutch, missing or improper shroud, or improper fan.

A high stall speed torque converter and high idle speed can also build heat from an auto tranny.

I agree it all about air flow at idle. I have been looking at electric fan to improve air flow . But if this additive works as good as it did today problem solved.
How can you tell if torgue converter is to high of stall speed ?
by shift points ?

If your engine and transmission are stock you don't have to worry. High stall converters are used to make it so you can drive an engine with a big cam on the street. The higher stall speed converter is used to get the engine into it's power band for operation.
