Engine gradually gets hot and can’t keep its cool
My 2005 Dodge Dakota 4.7 gets hot while driving w/ no A/C and in park while idling. It manages to stay at 180-195 right below mid notch when starting the vehicle and driving for about 30 mins then it starts getting hot gradually. When A/C is in use the cooling system simply can’t keep up cooling her down. I’ve replaced the water pump, radiator, fan clutch and thermostat. My guess there’s obstruction in the channel of the block of the engine or who knows??? I’ve opened rad cap to see if there’s circulation at its operating temp but all I’ve seen is just rising coolant more than moving fluid. I’m at lost with this truck and I’m trying to sell it. Any feedback would much greatly appreciated!!!
