Kevin,

I think you want to measure the temp of th= e coolant as it exits the engine. That way you know how close yo= u are to your upper operating limit. If you have a second input, you = can measure the temps after the radiator.

Oil temps are just the opposite... measure temps aft= er oil has been through the cooler and is entering the engine.
