Valeo Radiator Question

Have a 2003 E500 and production date early fall 2002. Have seen the MB bulletin of identifying the Valeo radiator that has caused leakage into transmission system. Identification points to sticker, then crimping method. Clarification is needed as follows:

1) Seems Part Number A2115003102 replaces the Valeo A2115000202 and if so, isn't A2115003102 a Valeo radiator also just a upgraded version?

2) Does the A2115003102 have the same crimping or similar to the Behr?

3) If crimping is same as the original radiator, I would presume the only way you can tell them apart is basically by the part number - where is this located? Is there anyway to tell the upgraded version from the original?

Feedback much appreciated.

Since you've identified that you have the old troublesome part number - if I were you I would plan for a changeout to a Behr radiator. If you do a search you can see plenty of threads regarding glycol contamination. Seems that the failure mode is so major that it isn't worth the risk with this known faulty radiator. In the short term you can extract out a little of your transmission fluid and send it to Blackstone Labs for analysis to see if you are contaminated - but this would only be a short term action only.
