I bought a 06, 997 S with a mere 21K miles. Pristine and dealership maintained by both of its low milage, two previous owners.
Already I have changed all the fluids, engine, transmission and final drive. My question is, the water pump is original. It does not
leak or make any noises. Should I replace it?. I am a gear head and do all repairs myself. The 997 engine is fairly
straight forward to work on. I am also planning preemtive change of the coolant tank, also the engine mounts need to be replace because of age, not milage.
Appreciate any input, for and against. I am a firm believer in doing preventive maintenance, because breaking down sux!!!!!
The water pump, being a purely mechanical device (unlike belts) is more miles dependent than age dependent for failure. I would leave it and change it when you do a belt service.
Mine was replaced by the previous owner. Its considered to be one of the more common things to go out on this model, as you know. Since its fairly cheap, and you do your own maintenance, I would say swap it out in a heartbeat.
If original, that water pump bearing has been sitting in coolant for 12 years. Change it when you replace the coolant tank as you'll have already emptied the system. Install the low temp thermostat and new serpentine belt at the same time and use new Porsche pink coolant in a 50/50 mix with distilled water.
^+1 with Petza.
Take a look at the coolant tank - does it have any evidence of the cracking normally indicative of aging?
Has the drive belt been replaced? It's also 12 years old...
If you need to replace the coolant, do it. Easy job and while you are there you may want to install a lower temp thermostat and a third radiator if you car doesn't already have them. If the coolant is not due soon, I think it can wait until then. Just my opinion.
