4 and 5 Cylinder Diesel Factory Block Heater to 1985

Fits 115, 116, 123 and 126 chassis diesels from 1968 up to 1985. The factory block heater is probably the most efficient block heater you can install as it heats the water in the engine block directly. It is not particularly easy to install. You have to get underneath the car with a big socket and long breaker bar to get the factory freeze plug out of the block - and more often than not they are really frozen in there. It is worth the effort if you live in real cold country.

For those who do not have the tools or the energy for this one check out our other block heater that installs in the lower radiator hose for turbo diesel models only. This unit is made by Zerostart in Canada and is a 500W / 115V unit.
