Well to start, they are 600W from Benz.

I did the head on my 104 motor a few years back and living in Minneapolis, block heaters are standard. I thought i would add one.

PAIN IN THE BUTT

I had the head and exhaust manifold off, and it was a 2 hour job, and the element is specific to each engine. I still have the aftermarket one i purchased that was supposed to fit, yeah right.

All my diesels have them, but my motivation is not the fuel mileage issues, but more importantly, the cold start wear issues.
