Just so everyone knows for future reference: the blockheater I recently installed in my truck is a Zerostart unit. Cast brass body, heater type cord with a plug cover. Its long enough to route to the grill on the driver side. Mine is a 1000W unit but they also carry the standard 600W. They are made in Canada. Construction is solid and well made. Installation went easy and has instructions.

Zerostart also sells the plug separately if you want to keep a spare/replace it and take a chance of the unit leaking/popping out.

The block heater in my truck I pulled seemed to be factory installed solid brass body and 600W with heater type cord. O-ring was leaking and cord was frayed at multiple locations. Mileage was about 180K.

Zerostart part numbers are as follows, for 6.2L and 6.5L Diesels:
1000W- 3100059
600W- 3100057
replacement cord(fits both models) 3600006

They also carry a large assortment of heaters for other applications.
