Radiator cap size

Use a flash lite and look threw your fins make sure the 3 rowe radiator is not plugged up from bugs, dirt and stuff so your fan can move air threw it :glasses7: remember these radiators need air to cross threw them to cool, some folks say a two core can cool just as good because air flows threw them easier, I have seen mud pore off the fins just buy useing a easy flow water hose on them.. Have you flushed the cooling system yet ?
