2002 Jeep Liberty Overheating

Asked by Aug 06, 2013 at 05:11 PM about the 2002 Jeep Liberty Sport 4WD

Question type: Maintenance & Repair

Bought a 2002 Liberty 3 weeks ago.  Does fine driving around town.  After about 30 miles on the highway with air conditioner running, it overheats.  Have had it in the shop twice with a new thermostat, new coolant with flushing, etc.  No improvement.  Help.

Sounds like the thermostatically controlled cooling fan "clutch" or the thermostatically controlled electrical "switch" is bad. The thermostatically controlled electrical "switch" completes the circuit and tells the electric fan to "turn on" once the engine coolant has reached a preset temperature. A thermostatically controlled "clutch" fan is attached to the water pump via a "clutch" (round cast metal disc which has a spring inside that the fan is attached to) and when the engine temperature is reached, the spring inside the "Clutch" tightens up and causes the fan to spin faster. Which ever one you have is broken and needs to be replaced.

the dip tube on the translucent reservoir may have fallen down inside~

if it ony overheats at hwy. speeds, the rad is clogged. no fan needed at this speed as ram air cools the radiator/coolant. If coolant cant flow, eng. overheats.

you could examine the "Hot spots" with a spot thermometer~

Where is the inner fan located on a 2002 Jeep liberty
