[ProjectM96]

I still have the old cap. I guess I will order a new one just incase and clean the radiators.

Thanks everyone. One last question. Is the IMS failure only known for 96-99 Boxsters, or the 2.7 engines in the 00-03 too? Because from what I see on all forums, only people with 99 and older models report IMS failures and replace them with the 2.5L engines.
