That’s right; both MGR OEM and EPDM ‘O’ rings flattened. That told me that it is not the material which is at fault, therefore it is not safe to conclude that the ‘O’ rings are not “fit for the job” particularly as many V6 owners have not had this problem at all!
Also Jim, I have found the notes obtained from the ‘O’ ring company which I used. They said that Viton is rated for use with water only up to 100 deg. C which, of course, leaves insufficient safety margin on a cooling system which regularly reaches that temperature. For that reason alone I would recommend that you return to the MGR OEM ‘O’ ring.

I tried a slightly larger ‘O’ ring Gary (32.92 mm ID x 3.53 mm cross section) and my thermostat housing was written off when attempting to fit it. So I would not recommend that approach.
