Block Heater Location
 

Heard it might be possible I have a block heater and just need a cord. How best can I try to see if I have one? The car is an 83 300D W123. Is it easier to find from under the car? I read some discussions about various types of heaters. My 2 cents, the car is fine 'till about 6 degrees F, at that point starting is an iffy proposition at best. I put a 500W Hologen lamp right up against the oil pan overnight, hit the glow plugs 5 times and it started on the first crank at -10 degrees F. I'm going to put an adhesive type heater on the thing if there is no block heater. I am using Power Service Diesel fuel supplement too to help combat gelling. On real cold days I run it up to temp at lunch time and this gets me through the day. I live in New England so this probably wouldn't work say in Canada or northern Maine.

rmmagow,

There was a recent post on this subject with a photo of the heater in the block attached. The location, as I recall is just a bit behind and above the front edge of the starter, on the passenger side of the block. If you have one, it will be obvious as there is a threaded plug with an electrical connection in the center that is readily distinguishable from a big hex plug. The unit is toward the rear of the block, at the same elevation as the other plugs along the side of the block (the others are not a hex headed plugs though). Jim
