I am not a mechanic but like to tinker. Bought this truck 3 years ago, only put 5k miles during this time.
Truck overheats on long highway drives or long up hills when driving at 70-75MPH. As I see the temperature gauge start to creep up I slow down and can control it that way but it is annoying and I am trying to see if I can get it fixed. Can idle or city drive all day long with no overheating issues at all. If I turn on the heat, it does not feel like it is as hot as it should be and has no effect on the truck's operating temperature, I am not sure if that is my mind playing tricks on me though. Besides overheating issue, truck drives great.
No check engine lights. No smoke out the tail pipe. No oil burning and no missing coolant in the last 5k miles. Oil looks normal, not milky.
Last year I overhauled the cooling system completely with OEM parts- radiator, water pump, thermostat, fan clutch, and of course fresh coolant. No change to symptoms. As far as I know, there is no way to bleed the coolant system beyond parking the truck uphill and letting it run for a while.
I am thinking this might be a small headgasket leak. I could do a leak down test but have not done that yet. Open to feedback and ideas/things to check.
