Question about 2000 Jeep Grand Cherokee
Cap off and cold once reaches running temp, shoots out the radiator about 1 foot. No water in oil or white smoke out exhaust. took out thermostat and bypassed heater. Added bottle of Bars Leak head gasket repair no luck. Seems to be cieculating through radiator which means radiator and water pump good right?
Does the vehicle overheat on the road? If it does and pushes big burps of coolant into the reserve tank then you could have a head gasket leak. Usually what happens with a head gasket leak is that the engine will often start and run normally but will soon start to push coolant out in a kind of foamy burp as the combustion gasses that accumulate in the engine block force their way out. You can have a small head gasket leak that allows combustion gasses to escape into the cooling system without getting coolant back into the engine and often the first symptoms of this kind of a leak is a motor that suddenly overheats, the heater quits blowing hot air and after a short while everything returns to normal for a day or so. As the leak worsens however it may keep pushing coolant out of the reserve tank with a cool or cold engine as the pressure builds to quickly for the reserve tank to handle it fully. Having said that if you have a perfectly good cooling system that is hot and take off the radiator cap it will spray blistering coolant coolant all over so never remove the cap from a warm or hot cooling system! Most additives won't stop a head gasket leak as there is just too much pressure for them to "stick" in the leak and they just get forced out of source of the leak. It's rare but you could have a water pump that's not circulating enough coolant around but usually you have different symptoms than this.
