My radiator started leaking so I replaced it and the thermostat was well. Now it is overheating and it ran fine before I had to replace the radiator. Anyone have any idea what is happening? Thanks
There is a funnel you can get made for burping the system which make it easier. I just use a old big funnel I had to burp my system. Take off the cap to the radiator and install the funnel and fill it 3/4 of the way with coolant. Start the jeep and turn on the heat. Make sure the funnel doesn't empty on of coolant and watch for bubbles to come up through the funnel. Ones the jeep heated up and the thermostat opens up and more bubbles will come up so I add coolant to funnel . Ones there is no more bubbles It takes about 15 to 20 minutes turn off the jeep and let it cool down. Then I plugged the funnel and removed it and put the cap back on and I was good to go. I hope this helps.whats the process for burping?
Good tip but only applicable to heater cores that have a control valve. TJs, at least the 03 here are full flow regardless of the heater settings.I dont know if this applies to jeeps but I was always told to run the heat on high while checking the coolant . helping to get air bubbles out of the heater core
