    Runniing Hot

    Has anyone experienced their GPRXP running hot? My 2008 engine seems to be running hot - especially on the head. The thermostat is opening like it should. I have closed loop system with a heat exchanger. Does the heat exchanger clog up with corrosion and require periodic cleaning or flushing like a car radiator? What is the normal operating temperature for this engine?

    I took measurements with a laser temp sensor gun. The coolant temp is 160f in the tank and the engine temp ranges from 140f around the exhaust manifold to 185 around the intake manifold. Intercooler is 110 and the heat exchanger is 120

    Thanks beerdart. I feel better. This engine seems to run so much hotter than the stock 4 tech in my 04 GTX. I just wanted to confirm that this is normal.
