I have the Jet 180* thermostat in my truck and love it. Letting the engine stay just a bit cooler seems to help keep the truck in its power zone. What I have noticed living here in Texas is that ( especially during summer months) when the truck has been running a while and the engine heatsoaks you can feel your truck losing power. Don't feel that with the 180*! no negative side effects during the winter either. Fuel mileage slightly better than with the factory 195*. Ok correct me if I am wrong on this.... In older cars the higher temps were used to burn off and prevent carbon build up. In modern cars and trucks detergent motor oils serve this same purpose. From what I have read you won't hurt anything unless you lower it all the way to 160*. if anyone is concerned about carbon build up then I highly recommend a treatment with Seafoam. I have used it and that stuff will blow that damn carbon right through your tail pipes! The 180* tstat is not a cure all but it sure does help!
