My '07 was blowing coolant out the overflow...I only saw this after my daughter would come home in the evening. I changed the radiator cap and now there is less coolant under the jeep, but it keeps emptying the coolant overflow bottle. Is the new cap maybe faulty? She tells me she hears gurgling when she starts it in the morning. She says temp stays steady in the middle.

Appreciate any ideas...thanks!

 

In my opinion and I had the no start issue and did a large write up on it, this doesn't sound like it's an electrical or ground issue.

 

 

I had a problem with my coolant for a while, I finally fixed it and it turned out the housing for the thermostat had a hairline crack which gradually got worse to where I finally located the leak. I had chase the leak for like nine months and couldn't figure out where the antifreeze was going. I believe at first it was being evaporated by the heat of the engine. I always would hear the gurgling when I stopped. Changed the thermal stat and the pressure switch. Never saw the crack in the thermostat housing until it finally gave started gushing out. Recommend you check the housing real close for cracks if you pull it off to change the thermostat. I think I paid $20 at. The dealership for the new one.

 

I found it today after driving it...driver's side of the radiator. So I'm replacing it, the hoses, t-stat and t-stat housing. Thanks.
