I have a '90 S/C I bought used a few years ago. The guy I bought it from advised me that he installed a 160 degree t-stat. He stated he put that one in for 2 reasons; 1 to allow the engine to run cooler causing the engine control unit to richen the fuel mixture & to help guard against blowing the head gaskets. Well, the head gaskets blew since I have owned this car. Anyway, the t-stat is starting to stick so I am going to replace it tomorrow. I have seen posts here stating that some use the 180 degree t-stat. What t-stat is the most popular? As I have always had plenty of heat in the winter, is there any disadvantages to using the 160 t-stat? Are the reasons stated to me for the 160 t-stat valid? any & all info is appreciated.
