why is my 2005 f150 running hot

Asked by Oct 05, 2016 at 03:54 PM about the 2005 Ford F-150 FX4 SuperCab 4WD

Question type: Maintenance & Repair

I have replaced the thermostat, fan clutch, and water pump and it still is running hot. A guy at AutoZone did a test that says I have and exhaust leak. Does this mean I have a blown head gasket?

Not necessarily, it could mean that there is a restriction on the cooling system, most likely the radiator, if you have one of those lazer heat detectors you can measure the effectiveness of the radiator when it is running, no hot or cold spots but an even cooling all the way down, and it will also tell you if the reading on the gauge are accurate.

Did autozone check for codes being thrown. No idiot light does not mean there is not a code being thrown. Is there a temp sending unit attached to the area of the thermostat.
