I was changing the oil in my 2008 LMM truck yesterday. Looking things over I noticed coolant following the block heater cord down. Appears to be leaking from around the terminals where the cord plugs in to the heater. I have never used the heater. I tried plugging it in and it snapped the breaker. Just wondering if anyone else has had this problem.

Searching here and there are post on this. Just have to have it replaced.
