Question about 2001 Jeep Grand Cherokee
Check the catlitic converters. it has two. After running hot , it probably runs a real lean mixture and that will ruin the converters, and car will run rough.And in some cases it will not stay running properly after getting overheated.
If the converter checked out ok then other possibilities to be checked are.
1) the radiator.
2) The radiator fan.It should start running when jeep gets overheated.If not then this is the cause.
3) The freon/coolant problem.Either a coolant leak or jeep low on coolant.
4) The water pump leaking.Or the water pump blocked or loose.Check it first before going for replacement.
5) The faulty ac thermostat.
6) The sensors.IAC and O2 sensors.
Get the coolant pressure tested first to continue troubleshooting.At any local car garage the pressure test is done.
