We were overheating replaced the radiator . When we got it back it started to
stutter when idle and low speeds and overheated again. There is no water in oil
no oil in water the resivory stays full but radiator needs water no leaks we can
find.no water out tail pipe
You're Cooling Fan isn't working?
get a radiator pressure tester at autozone and see if you can find a leak
Did they bled the air from the system after replacing the radiator ?
Is the coolant in the reservoir getting hot? Was the thermostat changed or has it been removed completely. Did you use 50/50 mixture in the radiator? Are the radiator hoses getting hot? They should. If no, could be a problem with the thermostat or water pump. Or a blockage in the system.
Did you find the problem? I have a Explorer 06 V8 and it did the same thing after I got a new radiator.
I have a similar situation 06 Ford Explorer overheating new housing and thermostat. Everything was well up until now serously overheating again specifically at stops. Any suggestions comments are appreciated. Thank you.
