Temp still rising

Asked by Feb 22, 2017 at 05:51 PM about the 1999 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I changed the thermostat in my 99 Jeep Grand
Cherokee Laredo 4.0L & my temp gauge is still
raising plus no hot air when I run the heat. Coolant
low light doesn't come on anymore & I flushed the
old antifreeze during the thermostat repair &
replaced it with fresh fluid. HELP ME PLEASE!!! I
need my Jeep working

COUPLE THINGS, THE WATER PUMP MIGHT NOT BE PUMPING COOLANT THROUGH THE ENGINE ANYMORE. WITH NEWER VEHICLES THE PROPELLERS ARE MADE OF PLASTIC AND THEY STOP WORKING AFTER A WHILE. NEXT, CHECK TO MAKE SURE YOUR FANS ARE COMING ON. LASTLY, IF YOUR VEHICLE HAS ONE...A COOLANT TEMPERATURE SENSOR.

All what Atuminaro says above is true, but after a coolant flush & thermostat change, you would need to purge the coolant system from air pockets. Check this video out.... youtube.com/watch?v=xeTgmdRkQtY
