Default overheating question

Vehicle
04 durango 4.7

Started overheating yesterday. I go check it on the side of the road. Fluid in reservoir is a gallon low. I fill it and it still runs hot. I then thought to squeeze the hoses while its hot and they are rock hard. This would indicate a bad thermostat correct? I replaced the stat about 5-6 years ago or 100,000 miles.

Bell tire was the only thing open and she has a line of credit there. I told them to change the t stat. She goes to pick it up and they said they didnt change anything because they couldn't get it to overheat. If it happens again bring it again.

I told them if it overheats and she is stranded again they will pay the tow bill and discount the repairs. I told them to change the tstat.

Did you pull the little bleeder plug to vent any possible air pockets when filling it back up?

Mechanical fan.

Did not know of blender screw. The tstat is at the bottom of the motor. Don't these pull from the bottom and dump back in up high. If so there shouldn't be air in the system...........I think..lol.

How coolant look like in radiator?

How many miles it had now?

Is radiator and AC/tran cooler clean of debris?

Does it had fan clutch on water pump? Can you feel it pulling air harder when hot?

If it still overheat you able have bad head. Had 94 Explorer that did like you describe it turn out bad head.

Overheating the 4.7L is bad news.

Sounds like the head gaskets may be bad. Loosing coolant, upper? hose is hard= combustion gas in the cooling system. pretty common problem.

This^^

First thing I thought of when you said you were a gallon low. All that fluid needs to go somewhere. If it is not coming out a hose, cap, or broken tube good chance it is going into the engine.

Pull your oil fill cap off that much coolant should give your oil a nice milky glaze of oh fuk my head gasket is shot.
