    160* thermostat

    Where can I buy a 160* thermostat for my 06' silverado? I tried buying one from summit but the damn thing doesn't fit. Suggestions?

    something else you can do that does work. You can drill several small holes in the factory Stat. the more holes the cooler the motor will run. Found out 4 holes netted 170* temps on a 408

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    Now THAT is good to know. I may just do that. Just to be sure tho, which disk do I drill on the stat? The side that inserts into the thermostat housing or the side that inserts into the water pump. Thanks a ton Quik
