hello everyone. I'm new with the Mercedes diesel world, got the car in may of this year, love the car and been doing lot of tinkering with the car my self. (try not to take to the shop too much) NOW I am really stumped . I'm trying to fined a 1978 300d radiator that has a filler neck on the radiator. I called local parts store and near by MB dealer (Washington) and no luck. At one point I was thinking of getting the 240d radiator but on the forms, lot of not so good things will happen to the car. Is there any way I can fined a '78 300d radiator OR use the turbo radiator (I think '81 and up) with the expansion tank. Has any on have or had that problem??? If do any ideas?????
