1996 Ford f150 overheating
I have a 1996 Ford f150 5.0 the other day
the temp gauge went from cold to hot then
back to cold the hot again I knew the
thermostat was stuck open so I took it had
it changed, new water pump, new temp
sensor, now on the way home it stayed at a
hot normal about where the L is, and it got
down to hot yet again, has been pressure
tested and showed nothing anyone can help
I'd appreciate it
Did you flush the radiator and engine with a good radiator cleaner? If the radiator is too dirty you will need a new one. Install new radiator hoses while you are at it,
Did you bleed air from system ?
I bled the air but no haven't flushed it yet
Prestone Super Flush is a very good cooling system flush.
Thank u I'll try that
Ok I've tried everything, nothing is working guage still on the L, and when I accelerate it goes way down to the National on NORMAL. I've changed the water pump , the coolant temp sensor, flushed the radiator, and replaced the fan do not know what else to do
I meant to say the n on normal not national
How are you bleeding the air from the system ?
And are you sure the thermostat is installed correctly ? Not saying you do not know what you are doing but I have myself have put it in wrong a few times. Trust me it is easy to do install wrong.
Ford put the thermostat in for me and I agree they are easy to install wrong I even ran without one to see if it changed things still the same
You may be due for a new radiator.
I hope not, it actually looks new to me
Let me ask you a question is your A.C condenser in front of or behind the radiator ? This is a long shot but I have had it happen before if condenser is in front of radiator maybe clogged fins on condenser causing not enough air flow to radiator. Clean condenser coil fins with a garden hose and nozzle or better yet a pressure washer using the the fan sprayer tip not the straight stream spray tip. Even if condenser is not in front of radiator would suggest try cleaning radiator fins.
It's in front
