Does anyone know where I can find the part no. for a Behr radiator for my 1990 300SE? I've been looking online and can't find it for sure! I think Behr is the OEM for Mercs. I want the part number b/c i recently pirchased a radiator from a local shop, and the person installing the radiator said the one I boght was incorrect. I just want to doublecheck here on the forum. If wrong, maybe i should purchase it here from people who know what their doing! Any help would be terrific! thanks!
