#1

I changed water pump and thermostat, flushed radiator and still running hot


#2

Did you check the cooling fans to see if they’re engaging?


#3

Possibly blown head gasket.


#4

Check the color/smell of the transmission fluid.

If the fluid is black and smells burnt, the transmission is running hot causing the engine to run hot.

#5

Are you sure that you put the thermostat in the right way.

If put in backwards it will overheat.

yes they are


#7

When refilling the cooling system remove the vent plug in the housing above the water pump, this will allow you to fill the engine with coolant, otherwise you will be refilling the cooling system every 2 miles.
