i got a new t-stat and rad cap,but my gauge never moves more than halfway towards the middle mark.but the truck is pretty hot,fan clutch is still good and water pump is a month old.how can you tell if the t-stat is 192 or 185?
I flushed my system today ran a mix of 50/50 checked it and had to add some coolant to get the freeze point up a bit and the boilover.. wasn't the best coolant i guess. I also ran some water wetter to help with cooling.
