Manufactured to Porsche's original specifications, these components provide precise fitment, durability and reliable performance under demanding operating temperatures and pressures.

Ideal for cooling system repairs, radiator maintenance or preventative servicing, this kit helps restore reliable engine cooling and maintain the original performance of your Porsche.

What Does This Kit Do? – Functions

• Efficient Coolant Circulation: Supports coolant flow between the engine and front radiators.
• Temperature Regulation: Helps maintain stable engine operating temperatures.
• Coolant Leak Prevention: Replaces deteriorated hoses and connections to help prevent coolant loss.
• Overheating Protection: Supports effective radiator cooling and heat dissipation.
• Secure Connections: Genuine Porsche connectors provide factory-correct hose connections.
• Original Fitment: Maintains Porsche factory cooling system specifications.

Why Replace These Parts?
Over time, radiator coolant hoses can become brittle, cracked or weakened due to constant heat exposure, coolant pressure and ageing. Damaged hoses or connectors may cause coolant leaks, reduced cooling efficiency and potentially serious engine overheating.

Replacing worn components with this genuine Porsche kit helps restore reliable coolant circulation, maintain secure cooling system connections and reduce the risk of unexpected cooling system failures.

When to Replace This Kit?

• Coolant Leaks: Visible coolant escaping from hoses or connections.
• Cracked Hoses: Hardened, brittle or deteriorated hose material.
• Swollen Hoses: Bulging or deformation caused by ageing or pressure.
• Engine Overheating: Rising engine temperatures associated with cooling system problems.
• Damaged Connectors: Cracked, worn or leaking coolant hose connections.
• Cooling System Repairs: During radiator replacement or major cooling system servicing.

Where Does It Fit on the Car?
Location: Front cooling system – left-hand and right-hand radiator hose assemblies.

The coolant hoses are installed within the front radiator cooling circuits, connecting the engine coolant supply and return pipework to the left and right radiators. The lower hoses carry coolant to the radiators, while the return hoses carry coolant away from the radiators through the cooling circuit. The two coolant hose connectors form part of the radiator hose connections, helping maintain secure assembly and proper coolant flow.

Fitting Positions:
Left-hand lower radiator coolant supply hose
Left-hand radiator coolant return hose
Right-hand radiator coolant return hose
Right-hand lower radiator coolant supply hose
Coolant hose connectors for the radiator assemblies
