All winter long I noticed a very small area of staining on the driveway and finally pin pointed what it is. Even though the coolant level was good...I found that there is coolant seeping out around the block heater at the block.
Spoke with the dealer and he said its quite common. I will see if I can tighten it some and if it stops...great. If not, it gets a new one asap.

Sure glad I found it like this and not with it falling out on the road.

I had a faulty block heater once on a gasser - it does happen. Eventually the heater shorted out and at -40 it was a tough start after working the night shift. Trouble was it was the middle of winter in northern Ontario (Timmins) and I had to change it in a very cold garage with minimal tools available. Get it changed before you really need it.

 

ditto that. mine was leaking too, very slight.
When I put a wrench on it it seems very loose.
I put it on the list of stuff the dealer will look at next week when I hit 35,500 miles...
