a 91 cummins 3.9 in a bread truck, new t-stat - 195 degree,
the radiator has been cleaned out by rad shop, ran it 15 miles
heat is good, temp shows ok, come back and check rdiator,
left side is nomal temp, the other side is ice cold
how come??
when the water get inside the left side it's warm and when it goes throw the rad toward the right it cool down by the air going throw the little finne of metal, so when it gets to the right its cold. If you make it work harder, do not worry it whil get warmer
