Information
Water coolant top hose to cylinder head.
This replacement coolant hose connects the upper radiator outlet to the cylinder head on early Porsche 944 models (1981-85). This hose conforms to original Porsche specifications in diameter, length, routing, and material grade. Constructed from high-temperature-resistant rubber with the correct wall thickness, it restores proper coolant flow, prevents leaks, and maintains the reliability of the vehicle's cooling system.
Fits:
Porsche 944 1981 - 1985

Diagram ref no 9A.
• Position on Vehicle: Engine bay – upper radiator hose connecting the top of the radiator to the cylinder head.
The upper radiator hose is a critical link in the engine’s cooling circuit: if it fails, you risk coolant leaks, overheating, engine damage, loss of heater performance and unexpected roadside breakdowns. Symptoms of a failing hose include bulging, cracking, coolant smell, visible coolant loss or temperature rise. Replacing the hose ensures proper coolant delivery, secure clamping, correct routing and long-term reliability.
When and why to replace:
• Visible cracks, bulging or soft spots on the existing hose.
• Hose has become hard, inflexible or distorted and may collapse under engine vacuum/pressure.
• Leaks or coolant loss are detected at the top radiator connection.
• During cooling system service: radiator removal, cylinder head service or hose age exceeds recommended lifespan (especially on classic vehicles).
• When the vehicle is undergoing restoration and you require correct-spec parts for peace of mind and authenticity.
