Hi everybody.
I just bought a 94 2500 4x4 with a 454. Although it looks like new and the previous owner had it maintained at the dealership, I noticed the coolant fluid was really dirty. So I flushed and rinsed the system 5 times with water and coolant flush. Unfortunately it still running a bit hot, the gauge goes up to the last mark before the 210 mark in normal driving conditions without towing. Is this maybe normal or should I check out the radiator itself?
