I'd like to see if this 2002 Clk430 has the radiator not known for the trans cooler leak, what am I supposed to look for? I did a search with no luck.

 

MB used both Valeo and Behr radiators during W208 production.

The radiators that leaked coolant into the transmission were made by Valeo.

 

Thank you, so is there a good way to identify which is which?

 

There should be a sticker on the radiator with the part number and manufacturer's identification (e.g. name or symbol) and/or impressed onto the plastic section.

It's usually on the driver's side or top of the radiator.
