The top left radiator feed hose carries coolant through the radiator circuit, helping regulate engine temperature and support efficient heat transfer. A secure, leak-free coolant hose is essential for maintaining correct cooling system pressure and protecting the engine from overheating.

Functions
• Replaces the top left coolant radiator feed hose
• Carries coolant through the radiator and engine cooling circuit
• Helps maintain correct engine operating temperature
• Supports cooling system pressure and coolant circulation
• Helps prevent coolant leaks, pressure loss, and overheating
• Replaces cracked, swollen, split, leaking, or aged original hoses
• OE Match replacement for cooling system repair and maintenance.

Why Replace This Part?
Coolant radiator hoses are exposed to constant heat, pressure, coolant additives, vibration, and age-related wear. Over time, the hose can harden, soften, swell, crack, split, or leak. A failing hose may cause coolant loss, low coolant warnings, overheating, steam, or reduced cooling system reliability. Replacing the hose helps restore dependable coolant circulation and protects the engine from heat-related damage.

When to Replace This Part
• The radiator hose is cracked, swollen, brittle, soft, or split
• Coolant leaks are visible around the hose or connection points
• The engine is overheating or coolant level is dropping
• Low coolant warnings appear
• The hose has become loose, contaminated, or damaged
• The radiator, water pump, thermostat, or coolant pipes are being serviced
• Preventative replacement is being carried out during cooling system maintenance.

Where it fits on the car
This hose fits in the top left radiator feed position within the cooling system on Porsche 982, 991.2, and GT4 models. It connects according to the factory coolant hose routing and supports coolant flow through the radiator circuit.
