Re: Coolant temps
I also did an antifreeze flush when changing the thermostat. I put mopar antifreeze. Can air in the system do that? It doesn't overheat. The truck is just running warm when driving and really warm uphill and when I get into the throttle. If I park the truck and let it run, the coolant temp will stay at around 203F.
I am really stumped! I have no idea other than to change the remaining cooling parts that I have not changed yet... (Fan, radiator, water pump).
A friend of mine mentioned the spark plugs and wires. But I really doubt that they can be causing temp issues. Maybe spark plugs and wires can help with rough idle? I'm not sure how to proceed.
