I have been introduced to the problems of the 3.7L motor. My latest issue is coolant loss. I lose about 1 gallon per hour. My marina pressure tested the system and thinks it is going through the #4 cylinder. This is backed up by the fact that the compression in that cylinder is 20% less than the average.
