1977 to 1985 Diesel Engine Critical Coolant Service Kit

So often neglected - yet critical to preventing pre-mature or catastrophic engine failure!

Why is this so important? It is primarily due to the age of these cars now and the fact that lurking problems can be hidden from visual inspection. There is not ONE diesel that Kent has looked at in the last five years that does not need this service! Even ones with under 150,000 original miles.

If you have a W116 or W126 300SD or a turbo 1981 to 1985 5 cylinder W123 Diesel you must pay attention to your oil cooler hoses. If one of these hoses fail you will destroy the engine unless you are in the habit of looking at your oil pressure gauge every 5 minutes while driving.

The Monark nozzles #120 are all gone, never to be remade. We do have a few hundred #128 nozzles still available. Kent and Kaia got together and started questioning why they would not work in the OM616 and OM617 engines. So in May of 2024 Kent decided to put them to the test.

I don't think there is any owner out there who has owned a 1978 to 1993 diesel automatic for any length of time and who has not had some sort of shift problem with the transmission. Maybe it was just a little jerk or a slipping shift. Maybe the rear end clunked hard when you came to a stop.
