Hello All,

This topic makes the rounds every month or so. The hoses start to leak after 2 decades and need replacement. Follow Diesel911's pictorial essay and you will fix the problem completely.

I bought hydraulic hose from professionals and 4 clamps. It is a little crowded in there but what job on a Mercedes isn't tight? There was a little anxiety getting the new hose to bend without kinking. You need to have the new hose the proper length.

The major reason to grind and not replace is; I can so no possible way of unscrewing those hose ends out of the oil cooler without stripping the threads. Years of heat have welded the hose fittings and cooler together. If the cooler gets stripped you have a real mess on your hands.

I don't think I properly thanked Diesel911 for his clever solution. Truly a triumph of pragmatism over orthodoxy.
