Overheating
Asked by Drew0808 Mar 24, 2017 at 09:12 PM about the 2002 Ford Mustang Coupe
Question type: Maintenance & Repair
I just replaced water pump, hoses and the
thermostat. My car is still overheating. Not right
away but it does. It overheats quicker when I put on
the AC. A while back the inside of the coolant cap
was muddy... do you think my radiator is clogged ?
The radiator was smoking the other day. Anything
helps

Does the cooling fan work? Mud in the radiator sounds like oil from a leaking head gasket. You could try flushing the radiator but if you are getting oil into the coolant the fix will be temporary at best.
From what I've seen it only turn on when I put on the ac. But haven't really checked the fan
But after I bought the car I realized it had no coolant could that bra reason also for the mudddy stuff?
The AC adds additional load on the cooling system. It is not the cause of your problem, just a symptom.
Oil and water mix can look like mud.
Yeah after I seen the muddy stuff I tried flushing it by opening something at the bottom of the radiator and ran water thru it. Water drained a lot of the stuff out but I don't think water can get all of it
I put water thru the coolant out the bottom
No leaking from radiator
At firrst this is how it looked. But it has no coolant just water. It doesn't look like that now the top of the cap is clean but idk about inside of the radiator
That is oil in the cooling system. I suppose it could be from the radiator if the transmission cooler is leaking oil into the radiator. Check for water in the transmission but I think you have a bad head gasket or a cracked head.

For sure, its either trans or Likely engine oil, Listen to F_O_R.
Okay thank you guys. I'll check after work and give a update
So you wouldn't think me getting my radiator flushed before would make a difference?
A flush is a waste of money until you get the real problem fixed.

After you fix it, a flush is a must, that is what the cooling passageways look like in the motor.
Ok but I haven't seen any of that stuff since the last time I flushed it with water.
F_O_R It was the radiator leaking oil inside and causing it to overheat not head gasket
After using k&w head sealer my car has now been overheating we have just flushed it out with a water hose and remove the hoses filled it back up I'm driving down the road and it started overheating again. We took thermostat out already
My 2003 mustang is overheating can anyone help me add changeThermostat but it still overheating please help

Could be a number of things. But check the areas that would be must likely. Water pump, coolant, radiator/fan cooling system (test fan relay by swapping same amp relay from a different one into its spot) than see if the fan kicks on when you crank the AC to full blast. Than check for leaks
