I did some preventive maintenance on my 2001 Boxster S with 26,000 miles on it; water pump, coolant, low temperature thermostat and motor mount. It was the first time in 14 1/2 years of ownership I have address these items.
I did the motor mount only because "while I am in there" not thinking that it would be bad. I also upgraded to the 987 motor mount.
When I removed it I noted that there were some surface cracks on the rubber. But, when I stressed it with a screwdriver I found that the cracks were very deep. Both side of the mount exhibited the same deep cracks.
I also found that the shaft of the water pump had some movement and there was coolant residue under the pulley indicating that it was leaking. It was slight and I hadn't seen any drips on the ground.. yet.
All in all it was a worthwhile project.
