Belt Replacement - 986 Forum - The Community for Porsche Boxster & Cayman Owners

At what milage should the belts be checked and replaced if required? My 01 Boxster 2.7L has 55K on it. Anyone know what the maintenance book says. I did not see anyplace in it about replacing any of the belts, like the Serpentine Belt or Polyrib Belt. Only to check the condition.

Polyrib belt is supposed to be changed at the 60K mile service interval. I just changed mine a couple of weeks ago with the help of a friend. Very simple job. I have an 01 w/ 49K miles on it. I figure the belt is cheap insurance, and don't want to be left stranded somewhere because of a failure.

Is the Polyrib belt and Serpantine Belt one in the same thing?

Same thing. Here are great instructions of how to change it:

As a side note, I noticed that prior to the belt change, whenever I turned on my A/C, there was a hiccup in the idle for a few seconds, but after putting on the new belt, the hiccup was gone. Maybe the old belt stretched a bit over time.

Thanks for the link. The link however shows a 2.5L engine. Are the pulleys and stuff all in the same place for the 2.7 L?

Hi,

The pulleys are the same. But, the Service Interval also has a time component - 5 yrs. - 60k mi. or 5 yrs. whichever comes first. The Belt may look fine, but contains internal cording for strength similar to a Tire. A simple visual check will not confirm the Belt's integrity. Hope this helps...

Happy Motoring!... Jim'99
