Product Information
Product Information
Radiator Hose Bottom To Water Pump.
The OE Match Radiator Hose Bottom to Water Pump is a high-quality replacement cooling system hose designed to carry cooled coolant from the lower section of the radiator directly to the engine water pump. Manufactured to OE specifications for fit, durability and performance, this hose is a vital component in maintaining efficient coolant circulation and engine temperature control.

Fits:
  • Porsche 944 2.5L 8V 1982-87

Diagram Ref No 8

Constructed from premium heat-resistant and coolant-resistant rubber materials, the hose is engineered to withstand continuous exposure to temperature fluctuations, coolant pressure and engine bay conditions. It ensures a secure and leak-free connection between the radiator and water pump, helping to maintain the effectiveness of the entire cooling system.  

What This Product Does:
  • Transfers cooled coolant from the radiator to the water pump.
  • Supports continuous coolant circulation throughout the engine.
  • Helps maintain correct engine operating temperatures.
  • Provides a secure and leak-resistant connection within the cooling system.
  • Assists in preventing engine overheating.
  • Supports efficient cooling system performance.
  • Contributes to long-term engine reliability and protection.

Symptoms Wear Or Failure:
  • Visible coolant leaks around the hose or connections.
  • Coolant drips beneath the vehicle.
  • Low coolant level warnings.
  • Engine overheating or fluctuating temperature readings.
  • Sweet coolant smell from the engine bay.
  • Cracks, splits or bulges in the hose material.
  • Soft, swollen or brittle rubber construction.
  • Coolant residue around hose fittings.
  • Loss of cooling system pressure.

Why Replacement Matters:

  • Lower radiator hoses operate in demanding conditions and are continuously exposed to coolant flow, pressure changes, heat cycles, vibration and environmental ageing. Over time, the rubber material can deteriorate, harden, crack or weaken, increasing the likelihood of leaks or sudden hose failure.
  • A damaged radiator hose can lead to coolant loss, reduced cooling efficiency and engine overheating. If coolant circulation is interrupted, critical engine components may be exposed to excessive temperatures, potentially resulting in costly engine repairs. Even minor leaks can progressively worsen and compromise the reliability of the cooling system.
  • Replacing a worn radiator hose restores proper coolant circulation, helps maintain correct engine temperatures and protects against overheating-related damage. An OE Match replacement provides factory-style fitment, dependable durability and long-term performance, ensuring reliable operation of your Porsche cooling system.

What This Product Does:

  • Directs coolant flow between the radiator and engine cooling components.
  • Acts as a distribution junction, ensuring coolant is properly routed through the left-side cooling circuit.
  • Helps maintain stable engine operating temperatures by supporting efficient heat transfer.
  • Provides a secure, sealed connection between multiple coolant hoses or pipes under pressure.

Symptoms Of Wear Or Failure:
  • Cracks in the distributor housing or failed seals/O-rings can cause visible coolant seepage.
  • Leaks from the distributor can lead to gradual coolant loss, requiring frequent top-ups.
  • Improper coolant routing or coolant loss can reduce cooling efficiency and cause unstable temperature readings.
  • A noticeable coolant odor near the radiator/front engine area often indicates leakage.
  • Signs may include cracked plastic housing, damaged hose connection ports, degraded O-ring seals, corrosion (if applicable to fittings)
  • Low coolant or temperature warnings may appear if leakage becomes significant.
  • A faulty distributor can cause pressure imbalance in the cooling circuit.

Why Replacement Matters:
  • Prevents coolant leaks that can cause low coolant levels and pressure loss.
  • Maintains proper coolant distribution, ensuring balanced flow through the radiator and engine circuits.
  • Helps prevent engine overheating, which can lead to serious and costly engine damage.
  • Restores system sealing integrity, especially if O-rings or connection ports are worn.
  • Protects surrounding components, as leaking coolant can damage wiring, sensors, belts, and other engine bay parts.
