I have a 2002 Jeep Liberty Limited Edition 3.7L V6 4WD. I have the following problems and I'm not sure if they're related to one another or not.
1) Engine leaks coolant very slowly.
2) The heater in the car takes about 12-15 minutes to produce warm air.
3) The vehicle gets on average, about 13 miles to the gallon.

Is there any chance these items are related?
