[quote=moparx]are you using a coolant recovery system now ?
this is an overflow tank that introduces the expanding coolant into the tank from the bottom, then with the double gasketed radiator cap, when the coolant cools down, it is returned into the radiator.
this will eliminate air in the system, thus allowing it to run cooler.
the factory system always had an air pocket below the radiator cap, and any excess coolant in the system was expelled onto the ground via the overflow hose.
maybe this will help you maintain your targeted temperature, or get closer to it.
