Water / Coolant radiator pipe kit. 
This OE Match radiator pipe kit is a complete replacement set of upper and lower radiator coolant pipes and hoses engineered to match the original Porsche parts used on the Porsche 996 Carrera 4S (C4S) cooling system. It includes all the essential coolant routing hoses and hard pipes needed to renew the cooling pathways between the engine, water pump, thermostat, and radiators.

Fits:
Porsche 996 C4S Manual Cars

Over time, coolant hoses and soft pipes can become soft, swollen, cracked, or brittle due to heat cycling, chemical exposure, and age. Hardened or deteriorated pipes can restrict flow or fail unexpectedly, potentially leading to overheating and engine damage. This comprehensive OE Match kit provides the key upper and lower cooling line replacements in one convenient package, ensuring reliable coolant flow and restoring system integrity.

This coolant pipe kit forms the primary coolant circulation pathways between the engine and radiators. It carries hot coolant away from the engine to the radiators for heat rejection and returns cooled fluid back to the engine to maintain optimal operating temperature - a critical function for engine health, performance, and longevity.

Coolant hoses and pipes are wear items in the cooling system. Age and thermal stress can weaken hoses, leading to leaks, coolant loss, and restricted flow - which in turn causes engine overheating and reduced performance. A comprehensive replacement kit helps ensure all major coolant pathways are renewed simultaneously, reducing the likelihood of future failures and maintaining stable engine temperatures under all driving conditions.

Replacing components as a matched kit also helps minimise the risk of partial repairs, where replacing only one hose still leaves adjacent aged hoses vulnerable to failure.

When to replace:
•  Visible coolant seepage or wet spots
•  Hoses that feel soft, swollen, or cracked to the touch
•  Radiator removal, thermostat water pump service, or engine cooling overhaul
•  Heat cycling has caused brittleness or surface degradation
•  Preventive maintenance on high-mile or enthusiast vehicles
