I have a 2006 Jeep Liberty. It ran hot on my wife to the point that it died. The radiator was busted. I replaced the radiator, thermostat, water pump and radiator cap. I drive 37 miles to work. Once I get to work and turn the jeep off it bubbles back into the reservoir and overflows. (During the trips to and from work the jeep never runs hot) I suspected a blown head gasket. There is no sweet smell to the exhaust or smoke. The oil is perfect. I conducted a block test and the test showed no exhaust gasses in the coolant. What could be causing the blowback in the reservoir?
Bubbles in the reservoir is a sure sign of compression being pumped into the coolant system!
Most likely a leaking head gasket or worse yet a cracked head!
Some on LOST have stated that the test for exhaust gas in coolant has not been all inclusive....
One test is to pull either the injectors or the glow plugs, let vehicle set overnight, spin engine over after setting all night and see if any coolant comes out whichever hole you opened up!
This will not tell you which is the culprit, gasket or cracked head. Only sure fire way is to pull head and have it pressure tested! If it tests good, then, have the head milled if warped, replace the head gasket, and install ARP studs...
Best of luck,
need help, just ask, lots of very good experienced advice available on this forum!
