Now when MOT passed looking for new heater matrix. Changed it once years ago but cannot remember the numbet. Foun from7zap four alernatives: 90487635, 9194857 -8 -9. This car has a winter package so I remember the matrix was thick and had several pipes in te back end. Any help most welcome!

Winter package means auxiliary pump in engine bay next to the coolant tank and heated seats and possibly front fog lights.

Basically any facelift Omega heater matrix will be the correct one

OK, thanks, have to check what I find. Just wondering about these four different spare numbers.

So I have all those mentioned above+LSD but still wondering about the matrix. Enclosed are two pictures; In both the left one is my original one, having 12 tubes in two rows slightly aside of each other while the cheap BEHR matrix has much less tubes (under the plastic cover) an all in the same row so the original rubber seal seen in lower pic does not fit. Do you have in e.g. U.K cars this left version which have price more than 200 euro? Any pictures available?

The one I removed from my car looked like the one on the left. Original GM part.
The one I fitted also looked like the one on the left. €18 pattern part from ATP


I did remove the top tank from the old one, and only a couple of the tubes were capable of passing coolant.


I should have bought new rubber seals for the pipes, but refitting them with a smear of sealant sorted the leak.
