Thermostat Part #

I'm looking at the thermostat part # and the 320 motor and the 32 motor are the same part #. Is there a difference?

C32 = 112 203 03 75

C320 = 112 203 02 75

The thermostat is an integral part of the outlet hose bung. Each model requires its own specific configuration.

Seal = 112 203 00 76. Same for both.

It seems when I look it up for the SLK they are the same part number. I'm using autohausaz.com, and they list the C32 unavailable. Different configuration in the SLK32?

I have a crossfire and can't seem to find much info about which is which, and this is the most knowledgable 3.2L forum I know so that's why i'm asking you guys.

Thanks.

Crossfire, huh? It’s all good.

I’ve been lurking on SRT6 section of crossfireforum.org because they’re into some pretty stout modifications.

Two pictures to share from the EPC. Both are from the SLK section.
Yours may be different, but the diagrams should point you in the right direction.
