Just asking, have you done a thorough flush on your block and radiator?

What I usually do is buy a can of the FLAPS radiator flush, pour it in, run the engine for a while. Previously, make a fitting to adapt a garden hose to the radiator draincock hole. Usually the drain is 1/8" or 1/4" NPT. I put a garden hose connected to the bottom draincock on my hot water heater. Running pressurized hot water in the bottom of the radiator, through the engine and out the top of the radiator will bring out an incredible amount of rusty sludge.

Refill with 50/50 and see if it lowers the idling temp.
