So I just got my new thermostat from the International Truck Center and looking at it, one side says "toward radiator" on the rubber ring. This very much looks upside down. Haven't yanked the old one yet for a reference. Not certain that will give me all I need as it may not be an OEM stat. Comments?

Thanks,

Cone side up, towards t-stat housing. Flat side down, into block.

 

That's what I would have guessed. Just weird it says on the flat side "toward radiator". Gonna go with your way. It's the way I always seen every stat.

Thanks!
