Information
Radiator coolant top hose - Upper radiator to water regulator housing.
Replacement hose for the upper radiator hose used in Porsche 928 models. It connects the radiator to the temperature regulator (thermostat/expander) housing, which is part of the engine cooling system. It ensures proper coolant flow between the radiator and engine, supporting precise temperature control.
Fits:
Porsche 928 1978 - 1984
Diagram ref no 19
• Location: Upper radiator hose — radiator to thermostat / water-regulator housing
• Use Case: Replacement during maintenance, cooling system overhaul, or when hose shows leak, age or wear
Manufactured to the original dimensions, inside diameter, and hose shape, this replacement hose ensures a proper fit and reliable seal without the need for modification. Made of high-quality, heat-resistant rubber, it withstands engine temperatures, pressure cycles, and coolant exposure, ensuring reliable, long-lasting performance.
This hose is especially useful when the original hose becomes brittle, cracked, swollen, or leaking, which are common problems in older cooling systems. Installing a new hose helps prevent coolant leaks, overheating, and potential engine damage.
Hoses degrade over time due to heat, coolant chemicals, age, and repeated expansion / contraction. A failing radiator hose can lead to:
• Coolant leaks under bonnet or beneath car
• Engine overheating or overheating under heavy load
• Loss of coolant pressure or coolant circulation
• Risk of engine damage due to poor cooling
Replacing it with a correctly spec’d hose helps maintain coolant circulation, prevents leaks, and safeguards the engine’s cooling system reliability.
