Hi, I would like to swap the 200TDi oil-water-radiator (fitted to my 109 S3) for an " only -water"-radiator, which is exactly the same size as the genuine one. The engine oil will be cooled by a separat oil-cooler, fitted in front of the rad, just under the TD5 intercooler. My search leave to no results by now. Can anybody hel
Regards
Heinz

I've been wonderig about smilar for the future 200tdi conversion in our 1986 Ninety (from 2.5d)

I decided to use the 200tdi radiator & plumb the oilcooler into it as the coolant warms the oil on startup then cools the oil

Rich.

You could use the original rad, just block off the oil in and out ports, then mount your remote oil cooler elsewhere
