Started my 1500 today and notice that the temp on the gauge (Sunpro) was rising rather rapidly. It settle at about 205 deg. After killing the engine, I check with my heat gun an there was a big difference at the top of radiator and bottom. Top was around 170 and the bottom was around 82 degs. just warm to the touch. This model don't have a water pump. just thermo suction. What would cause this?
