My cherokee keeps loosing coolant
My Cherokee keeps loosing coolant. I keep filling the coolant reservoir, but then the next time I check it's empty.
I don't see any leaks. I also checked the oil and it's not mixed with coolant.
It has a new water pump, theromostat, and radiator cap.
What's going on here?

Doubtful it's a manifold gasket. Would ether suck or blow!
Wet/dry compression test. Have it at least warm if you can. Do five or seven strokes with all the plugs out. Write down all the numbers, one through six. Add a couple tablespoons of oil into all the holes. Crank it a bit to make sure that oil got around into the rings. Do a second set of numbers.
If compression comes up on a cylinder suspect rings, if it stays low suspect valves or the head gasket.
By the way it will smoke allot after you put the plugs back and fire it up!
