OK, taking it one by one. First, 7 vane pump because I have a small pulley.
Second, possible blockage through radiator....that's possible but since the upper hose empties directly into the top radiator tank I should see lots of turbulence in the water whether the tubes are clogged or not, RIGHT?? Besides, when I looked at the tubes they looked clean and clear.
Third, you're saying flush the system and replace water pump?
Fourth, Shoot it!! Now that's a GREAT IDEA!!!
