Genuine 986, 987, Boxster, Cayman, 996, 997 & Carrera coolant expansion tank cap and header tank & reservoir lid.

These caps seal your cooling system. They also act as a safety valve. The lid keeps the whole cooling system pressurised and operating at a predetermined pressure. Excess pressures are relieved through the lid's integral safety valve.
A faulty lid can lead to engine overheating and excessive gas build up and pressurisation of your expansion tank.

NO specialist tools are required to fit this part. It's easy and straight forward to install. Just make sure your engine is completely cold when you do this.

This will fit the following Porsche vehicles :-

986 Boxster (all models built 1997-2004) & Boxster S (all models built 2000 and 2004)

986 Boxster was showing coolant condensation on boot lid above tank. Upgrade to 04 cap has resolved this. Genuine Porsche part, reasonable price & fast delivery.

Coolant leak

Porsche 996 C2 slowly losing coolant from expansion tank. Problem traced to the original factory fitted tank cap. Was aware that a newer Porsche design cap was available for the 996 and other models. Frazer Part had the new cap in stock and at a competitive price. With speedy delivery I now have a cool running car again and don’t need to regularly top up. Highly recommend this upgrade to other 996 users.
