Overheating

Asked by Sep 04, 2011 at 11:30 AM about the 1998 Jeep Cherokee 4 Dr SE

Question type: Maintenance & Repair

I've got a 98 Grand Cherokee 4.0 inline 6 that is registering overheating.  Within the last week, I have replaced the thermostat, fan clutch, water pump, coolant temp sensor, drain and flush system, and replaced with fresh antifreeze.  It is still registering at about 240 and a slight smell of antifreeze.  Heater core was replaced about 8 months ago.  I can't rack my brain anymore!!!! NO LEAKS, JUST THE SMELL AND THE OVERHEATING GAUGE......WHAT ELSE IS THERE???????????
