sierra ss Posted January 23, 2009 Report Share Posted January 23, 2009 Installed mine today and now the truck runs 10 to 20* cooler and 10 to 20* warmer. Has any one else ever had this problem? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted January 23, 2009 Report Share Posted January 23, 2009 I am confused by your description......if by 20 degrees warmer you mean near 210, the guage will reach near 210 when sitting stopped dead in traffic.....once moving, the guage will drop to around 180. The operating temp of a 160 t-stat is usually 175-180*......... Quote Link to comment Share on other sites More sharing options...
