97 jgc ltd. loosing coolant

[cbftbl87]

I have been losing coolant recently from my overflow container. Radiator is full so that's where it's going. It happened suddenly and is losing about a half gallon a week. Is this too much for a head gasket? Passenger floor is dry so I don't think it's the heater core. Also, i never see any on the ground. Any ideas? It's the 4.0 liter, 4x4. Thanks a lot.

Could be the Water Pump, it has a weep hole that will leak coolant when the bearing goes bad. could just be leaking from there and is burning off.

Could have a hairline crack in the side of the radiator, they are made of plastic. Check at bottom of radiator to see if wet at all.

Same thing happened to my with my 95 JGC Lt, I had to replace the water pump. it was leaking from the weep hole. found a new water pump for 60 dollars on line good luck
