engine hot, loss of coolant

[brett914]

I just completed a pump replacement on my 02 Boxster S. It had to be about the easiest water pump replacement I've ever done (so far). The wierd thing is the car still overheats event though the reservior appears full. (I will take the bleeding suggestion above)
On a related note, the plastic impeller on the old pump had all its fins chewed off (new one is metal)....are those little pieces of plastic in the system causing issues?

The fins then are still in the system, restricting flow, somewhere, hopefully they are stuck where the hoses bend or attach to the radiators.

If it is in the motor, then its bad.

Surley the enginers at porsche thought of this and made the flow from the pump to the front, to the radiators, then to the motor. So if anything broke loose, it would be stuck in the first radiator.

JHandy,

That is exactly the news I had hoped to hear!
I will feel less hopeless pulling hoses off if I feel there is a good chance those little pieces aren't in the water jackets!
