Running hot
My engine runs hot (220-230) whenever I'm driving up any kind of incline. Once I start to flatten out it gets down to normal temperature. I've already changed the radiator, t-stat, clutch fan, radiator cap, water pump, radiator hoses and even added a pusher fan. Any ideas? It's the 5.2l.

The engine will run a little warmer with an extra load on it, such as climbing an incline. What is your anti-freeze to water ratio? Too much anti-freeze will not cool as well as a 50/50 ratio.

How does the engine feel? Enough power? A restricted exhaust will cause the engine to run hotter.

might be air in the coolant system preventing the thermostat from opening, is the system bled out?
