Water Pump and Ancillary Hoses
By OE Match
- Porsche 944 2.5L 8V 1982-87
- Porsche 944 2.7L 8V 1988-89
- Porsche 944S 2.5L 16V 1987-88
Direct-fit replacement hose for the radiator lower hose on Porsche 944 road cars (models 1985 through 1989). It connects the bottom outlet of the radiator to the water pump inlet, forming a critical part of the engine’s coolant circulation system. Precision-moulded to original shape and dimensions, this hose fits exactly as the factory part did - ensuring correct routing, secure sealing, and reliable coolant flow under pressure and high engine temperatures.
Fits:
- Porsche 944 2.5L 8V 1982-87
- Porsche 944 2.7L 8V 1988-89
- Porsche 944S 2.5L 16V 1987-88
• Application: Lower radiator hose — radiator bottom outlet → water pump inlet.
• Ideal Use Cases: Cooling system maintenance, hose replacement during service, overheating prevention, or when original hose shows wear, cracks or leaks.
Coolant hoses are subject to continuous heat cycling, coolant chemical exposure, and flexing from engine vibration. Over time the rubber can degrade - becoming brittle, soft, cracked, or swollen. A failing radiator hose may lead to:
• Coolant leaks - causing low coolant levels or visible drips under the car.
• Engine overheating - risking long-term engine damage or immediate breakdown.
• Loss of coolant pressure or air ingress - potentially reducing cooling system efficiency.
Using a new hose restores reliable coolant circulation, helps prevent leaks, supports stable engine temperature, and reduces the risk of costly engine overheating or damage.

OEMatch Water Pump and Ancillary Hoses — Durability, Sealing, Performance
OEMatch supplies water pump and ancillary hoses for Porsche models, offering direct-fit alternatives made to original-spec dimensions and tolerances. Many owners search for genuine or OEM water pump and ancillary hoses; these OEMatch options are designed as practical replacements when original items are unavailable and support routine cooling system maintenance. Parts are selected to suit common Porsche engines and cooling layouts.
Available Types- Primary water pump hoses
- Radiator upper and lower coolant hoses
- Heater, bypass and ancillary turbo coolant hoses
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original water pump and ancillary hoses. OE (Original Equipment) refers to parts matching original specifications for the water pump and ancillary hoses and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM water pump and ancillary hoses engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch offers a wide selection of cooling hoses and related items for Porsche applications, cataloguing thousands of part numbers and OE cross-references and continuing to develop new lines to keep older vehicles serviceable. Materials and construction are chosen to withstand heat, vibration and coolant chemistry typical of Porsche engines.
Benefits Include- Restored coolant circulation and stable operating temperatures
- Reduced risk of leaks and pressure loss at hose connections
- Materials chosen for heat and chemical resistance to extend service life
- Thermal degradation from repeated heating and cooling cycles
- Rubber hardening, cracking or swelling due to age or incompatible coolant additives
- Abrasion or chafing from contact with adjacent components and clamp failures
Failing hoses can interrupt coolant flow and lead to overheating that damages cylinder heads, gaskets and other engine components. For Porsche models, timely replacement protects engine integrity, maintains consistent operating temperature and reduces the likelihood of roadside breakdowns by restoring system pressure and leak-free connections.
Advantages- Direct-fit alternatives made to original-spec dimensions and tolerances
- Constructed from reinforced materials to resist heat and coolant degradation
- Compatible with factory coolant circuits and common sensor layouts
