Question about Jeep Grand Cherokee
When the radiator and/thermostat is replaced in a Jeep, the system needs to be "burped" of any air let into the system. Park the vehicle on ramps or an incline with the front end pointed up. Remove the radiator cap and run the engine. If there is air in the engine, bubbles will escape from the radiator cap (which is now the highest point). Watch the temp carefully while doing this for overheating. If it still overheats, my best inclination is that the thermostat itself was installed backwards and there is no flow. This is easy to do if not paying close attention, it will fit either way. Could also be a bad thermostat. If the burping doesn't work, install a new thermostat paying close attention to flow direction.
