The radiator still looks clean--there doesn't seem to be any scale build up.....
Does anyone know if there is a difference between a water pump in a 440 motor that has a/c vs. one without a/c???? if so--where can I get one??? I was told the regular pump has 8 blades and the a/c one only has 6 blades to push the water......Thanks again for all the help!!!!
