Revision:
This bulletin replaces bulletin Group 1, # 7/07, dated February 27, 2007.
Concerns:
Coolant pump
Information:
Test results for coolant pumps supplied with damage category "leaking".
Most of the coolant pumps returned to Porsche under warranty with the damage category "leaking (e.g. SA-5014)" were indeed found to have
traces of coolant residue, but a subsequent function test has shown that almost all the coolant pumps that were diagnosed as leaking were actually
fully functional and were not leaking.
In this case, we must point out that the presence of slight traces of coolant residue on the coolant pump housing is not an indication that the coolant
pump is leaking and needs to be replaced.
Work Procedure:
Before replacing the coolant pump, it is important therefore to use the following criteria to first check whether there are compelling technical
grounds for replacing the coolant pump:
1 IF there are slight traces of coolant residue on the coolant pump housing when you examine it during damage diagnosis [and] the traces of
coolant residue are dry and there are no apparent drops forming THEN there are no technical grounds for replacing the coolant pump (see
example --> Figure 1 ).

2. IF there are significant traces of coolant residue on the coolant pump housing when you examine it during damage diagnosis [and] the traces of
coolant residue are moist and drops of coolant have formed on the housing THEN the coolant pump must be replaced.
--> Remember to take photographs of the leak and attach them to the PQIS job, along with all the required documentation to support the coolant
pump replacement.
