Overheating!!

My car keeps over heating first I flushed it.
Then that didn't do it.
So then.
I replaced the thermostat and gasket.
I took it to Midas and nothing came up on the computer meaning as everything is good.
But.
It keeps running hot!
What could it be?
I need help.

Whenever I've had problems with heats its been my water pump or radiator. They both started leaking around the same time for me.

Take the radiator cap off and let it run. If you have circulation the water pump is good. Next by some radiator flush and hope it works.

It depends. Is it the radiator and not the water pump? For $5-7 it is worth a try. My radiator only overheated in the summer when it was bad. But, we do not get supper cold on the gulf coast.

How is the car running, otherwise? Have you noticed any new misfiring or anything different since this overheating problem began?

In the city it does fine cause the speed limits are 20-40 but when it gets on the highway and get to 60 and over that's when it gets hot

Well either like yellow said, maybe a clogged radiator, OR, you may have a blown head gasket.
Are you having to add coolant to the system regularly?

Original radiator? Never been flushed prior to you? Try some radiator flush, follow it's directions, and see if that helps to unclog what appears to be a plugged up core. If it does not improve, it may be time to have the radiator serviced professionally, or replaced.

That is if your sure there are no leaks, and the radiator is clogged. Does this year Mustang have a radiator cap? If so, you can somtimes see the core tubes through this opening. Sometimes you have to remove the upper hose. Sometimes it is impossible to view the core.

I once had a water pump pulley spin on it's shaft; sometimes the temps were fine, and then out of no where, the temps climbed to the peg mark. The water pump pulley was slipping at higher speeds (engine RPM) on the impeller shaft, causing the impeller not to spin water (basically the water "pump" was not circulating water at higher speeds.

See if you can find a way to clamp onto the shaft of the water pump, and then spin the pulley by hand. This may be impossible if the pulley mounts over the shaft.

even could be a hose is heat rotted or flimsy and when it sucks the fluid the hose closes on itself like old rubber
