I have an 89 mustang 5.0, and i am a new owner. The engine seems to run real hot, but my temp gauge does not work. I can't figure out the temp gauge, and is their something I need to look at to help cool my car.....thanks matt

first off get a temperature gauge on it, 190-220 ish degrees seems hot, but is about right for most engines (220 is on the high side, though) as for the temp gauge, it's either the cluster, wiring or the sensor itself, but the gauge isn't terribly accurate, if it were me.. I would run an aftermarket temperature gauge (and one that uses its own sensor, not the stock signal..)

If it does indeed run hot, there could be several reasons why.. but with the age of the car most prominent would probably be sludge built up in the coolant passages... nothing a flush wouldn't fix... beyond that you could cool the car more with a better cooling fan, colder thermostat, etc

Don't get me started on problems

however, Scut, have you tried changing your fans.. to run at a lower temp?

Not yet....im thinking about getting my car tuned and have them change the temp at which the fan kicks on....it is an electric fan that seems to suck a lot of air in, just not soon enough

On my 95 I had the same problem. Got the fans to come on sooner and no more overheating.
