The radiator is fine, it works no probs. The thermo fan behind it is cactus. So is the water pump. Coolant is leaking out of the disintegrated water pump into the oil pan and other places so the fluid is mixing and going through the engine, it also has a massive leak, you have to refill the radiator before each trip.
You said that the radiator works fine but then u said the radiator has a massive leak and needs to be refilled after each trip? So is it good or bad? What other parts would need to be replaced?
