77 to 85 Diesel Oil Cooler Thermostat Location and Theory of Operation

[@richardgreene3460]

This video is your BEST or near the top of the best from the hundreds videos you have made. In my 40 years of driving/working on my W123/W126, I have heard very little mention of the oil cooler thermostat!

No words. I am sure that even mercedes mechanics do/did not have such a precise learning during their training. Congrats!

I had what I thought was a rear main seal leak on my '81 240D for some 20+ yrs. After watching one of Kent's videos I installed a filter housing gasket using his kit. My garage floor is now clean. You definitely need the special wrenches to undo the oil cooler lines. Thanks Kent!

For a simple engine like that there has been some serious engineering done. Never imagined there could be a separate thermostat for the oil cooler. At least MB did not connect the oil cooler directly with the engine coolant. Seen cars where the oil cooler internally rots away and the coolant will make its way into the engine. Usually the case with vehicles where the oil cooler has been integrated into the radiator as one unite. Very cool video, I like the part where you cut open the oil filter housing to show us how the oil cooler thermostat works.

Dose the gasoline engine have the same typ of oil cooler thermostat ? 🤔

[@juhoreiss4691]

What about 603 housing? Is the thermostat in the same place?
