I just did a top end rebuild on '02 KJ Sport 3.7 4x4 for blown head gaskets. While trying to bleed my cooling system, I took off the radiator cap, turned on the heater and let it run. Suddenly it spit and sputtered and the coolant level dropped, I filled it back up, replaced the cap and cut it off. Drove it a bit today (yesterday, now) and it run a bit warm, so I figured it didn't bleed out completely. When I got home, I let it cool off and went thru the procedure again. This time, instead of spitting and sputtering, it whimpered a bit and the level dropped about an inch. I filled it up again to the fill mark, replaced the cap and cut it off. An hour later I went and checked it and the reservoir was almost empty, so I topped it back to the mark. Then just a little bit ago, I went out and it was a tiny bit low, so I added a bit more. Is it normal to have that much air bleed out? Am I losing coolant elsewhere? I have seen no external leaks. The oil looks fine. It is steaming but thats from the cold weather. It doesn't have a sweet smell to it that i can tell, tho sometimes my sense of smell isn't all it could be. It, also, doesn't miss, which is a sign of a blown head gasket (tho I literally just replaced it 4 days ago). Is it bleeding out still or am I just being overly optimistic?
