I ordered a new thermostat housing cover for my 1989 190E. My friend had leaned on the connecting nipple and it broke. I was sent a metal piece that goes to the radiator fine, but doesn't have the nipple to go to the overflow tank. I've searched online for hours and can't find one that's like the original.

You need part number 103-203-05-74 housing, 102-990-00-88 fitting, 915036-005100 hollow bolt, & (2) 007603-008100 crush washers. THAT is for M103.942 engine, 6 cylinder

Thanks for the help. I couldn't get the part online, to I had to go to a dealership. The metal part is a lot better than the oem plastic one.

This post helped !
the dealer service dept. had absolutely NO idea what parts to get to replace the OEM plastic cover. I had to print this and take it to the parts dept.
I wonder how the mercedes parts dept. operates without such essential information....
