What This Part Does / Functions
• Seals the coolant flange to the engine / cylinder head
• Helps prevent coolant leaks from the flange joint
• Maintains cooling system pressure
• Supports correct coolant flow through the engine

• Replaces a compressed, torn, brittle or leaking original gasket
• Provides correct OE Porsche gasket profile and fitment
• Supports reliable cooling system operation after hose or flange service.

Why Replace This Part?
Coolant flange gaskets are exposed to heat cycles, coolant pressure, age and corrosion around the sealing surface. Over time, the gasket can compress, harden, tear or lose its ability to seal correctly. A leaking gasket can cause coolant loss, low coolant warnings, air pockets in the cooling system or overheating. Replacing it with a Genuine Porsche OE coolant flange gasket helps restore the correct seal and supports reliable cooling system performance.

•  Coolant leak around the water flange
•  Dried coolant residue near the cylinder head / hose flange
•  Low coolant level
•  Coolant smell from the engine bay
•  Steam or coolant seepage after warm-up
•  Cooling system pressure loss
•  Air entering the cooling system
•  Overheating caused by coolant loss.

When to Replace This Part
•  Whenever the coolant flange or water hose socket is removed
•  During coolant hose replacement
•  If coolant is leaking from the flange joint
•  If the gasket is brittle, torn, crushed or damaged
•  During cylinder head, thermostat or cooling system work
•  When replacing the water hose flange / coolant outlet
•  During engine rebuild or cooling system restoration
•  Whenever Porsche workshop procedure recommends replacing the gasket after removal
