My Boxster is a 2000 S with low Kms (42,000) with original Water Pump and AOS.

I have read that a good check for the AOS is to pull off the Oil Cap at idle and if it's difficult to remove then AOS needs replacing.

Thanks in advance.
A better check is simply if there is any oil residue on or in the vent pipe on top of the AOS.

Why swap a perfectly good part(s)???
