Replacement bleed valve cap with 8 screws and seal.

Replacement coolant bleed valve cap for selected Porsche Boxster, Cayman and 911 models.

This cap mounts to the coolant distribution housing and helps provide a secure seal at the cooling system air-bleed point. It is supplied complete with 8 mounting screws and the required sealing ring for a precise and reliable installation.

Suitable for the following models:

Porsche 996 1998–2005
Porsche 997.1 2005–2008

Designed to match the original fitment, this bleed valve cap helps maintain cooling system pressure during coolant expansion and contraction. A worn or damaged cap can lead to coolant leaks, pressure loss, trapped air and reduced cooling performance.

Supplied with:

• Coolant bleed valve cap
• Sealing ring
• 8 mounting screws

Common signs of a worn bleed valve cap can include:

• Coolant leaks around the bleed housing
• Loss of cooling system pressure
• Difficulty bleeding the cooling system correctly
• Air pockets in the coolant system
• Overheating or reduced cooling efficiency

Replacing the bleed valve cap helps restore proper cooling system sealing and supports reliable engine temperature control.
