Why does the coolant in the overflow jug bubble on a 2003 Jeep Grand Cherokee Laredo even when the motor is not hot just changed the radiator.
Could either be air in the cooling system or first stage of a blown head gasket, check for coolant in the oil or oil in the coolant, if those are clear and you don't see any white smoke out of the tailpipe then have a block checked performed just to make sure.
