Overheating and not starting

Asked by Robin Apr 10, 2023 at 05:11 PM about the 2002 Jeep Grand Cherokee Sport

Question type: Maintenance & Repair

I have a 2002 Jeep Grand Cherokee Laredo Sport.
The fan, the one in front of the radiator is not turning
at all. Driving down the highway at 60 mph it will
start to get hot. Alit of the time I can a void an
overheat by put the car in N for a bit. And it will start
cooling back down. The greater only blows old air so
turning the heater on is no help. Today it wasn't
cooling down I N. I had to pull off the road. As soon
as I took my foot off the gas it died. It steamed for a
little while, maybe 10 minutes or so. It would not
start. I checked the overflow jug it was maybe 1/2
inch low so I added antifreeze to the line. It started
and took me about 2 miles down the road. Temp was
about 200. I noticed there was steam or smoke
coming in my passenger door so I pulled off the
road. As soon as I took my foot off the gas it died
again.  I can't put fluid in the radiator unless I can
start it. So I can only go on the overflow. What is
going on with this Jeep? I know I need to figure out
why the fan is not turning and fix it.  I am single work
20 hours a week and shop rates are outrageous.  Any
help would. Be greatly appreciated. Thank you

Why can you not check your radiator unless it’s running? If your reservoir is half full then your coolant is low. You may have a clogged radiator, busted thermostat or potentially need a new water pump.

Sounds like a couple of problems, the first one is a plugged radiator, there would be enough air flow through the radiator at 60 to keep the engine at normal temperature. The next is electrical, the fan in front is for the AC system, if the AC works that fan will turn on with the AC compressor, if the AC doesn’t work then the fan won’t work. The main cooling fan is controlled by a temperature switch, so the switch, wiring and the fan motor all need tested.
