Cant Find Lower Temp Thermostat

[Merc1]

I have been looking for Thermostat for 98 e320, all I could find is 87 C here in USA. I heard in Asia they sell lower temp Thermostat.

I dont know what the deal is maybe it has to do with the emissions here.

Does anyone know what temp they sell beside 87 C?

My temp is running around 90 97 C, I know mercedes tell people it is normal. However, I would feel comfortable running around 85.

I called the dealer here in USA and few other stores, trying to get a lower temp, no luck.

If anyone has any info about getting the lower temp Thermostat, please post.

Thanks
