Product Information
Coolant Hose, Feed.
The Coolant Hose, Feed is a genuine Porsche coolant hose designed to carry pressurised engine coolant through the cooling system feed circuit. This hose helps maintain correct coolant flow between key cooling components, supporting stable engine operating temperatures and proper heater performance. It is an OE replacement part used on Porsche 970.2 Panamera models.

Fits:
  • Porsche 970.2 Panamera S V6 Turbo 3.0L 2WD (420Hp) 2014-16
  • Porsche 970.2 Panamera S V6 Turbo 3.0L 2WD Executive 2014-16  

Diagram Ref No 4 (Diagram Ref No 5 and 6 Included)

What This Product Does:

  • Feeds engine coolant through the cooling circuit to ensure proper circulation.
  • Helps maintain stable engine operating temperature by allowing coolant to move efficiently through the system.
  • Supports the heater circuit, helping deliver hot coolant needed for cabin heating via the heater core.
  • Provides a flexible connection that absorbs engine movement and heat expansion, reducing stress on rigid pipes and fittings.

Symptoms Of Wear Or Failure:
  • Coolant may seep or drip from the hose itself or from the connection points/clamps.
  • Repeatedly needing to top up coolant is a strong sign the hose may be leaking
  • A leaking or weakened hose can reduce coolant circulation and system pressure, causing overheating.
  • A noticeable coolant smell around the engine bay or under the vehicle often indicates a small leak.
  • Visual inspection may show cracking, bulging , deterioration, hardened rubber
  • If coolant flow is restricted or low, the heater may blow lukewarm or cold air.
  • Many Porsche models will trigger a coolant level warning when a hose begins to fail.

Why Replacement Matters:
  • Prevents coolant leaks that can lead to low coolant levels and loss of pressure.
  • Helps avoid engine overheating, which can cause serious engine damage and expensive repairs.
  • Maintains reliable heater performance, since the cabin heater depends on proper coolant flow.
  • Protects other cooling system components by preventing air entering the system and reducing strain on the water pump and pipes.
  • Improves reliability, especially since coolant hoses degrade over time from heat cycles and pressure.

Diagram Ref No 8 (Diagram Ref No 9 and 10 Included)

What This Product Does:

  • Routes engine coolant through the cooling circuit to maintain correct operating temperature.
  • Supports the heater coolant circuit, helping supply hot coolant to the heater core so the cabin heating system can produce warm air.
  • Helps maintain proper cooling system pressure and flow, which is essential for preventing overheating and ensuring stable engine performance.

Symptoms Of Wear Or Failure:
  • Visible coolant dripping or wet staining around the pipe, joints, or connection points is the most common sign.
  • The coolant reservoir may repeatedly drop even if no obvious leak is seen right away.
  • A leaking or restricted coolant pipe can reduce coolant circulation, causing overheating.
  • If coolant flow to the heater circuit is reduced, the heater may blow lukewarm or cold air.
  • You may notice a sweet coolant odor in the engine bay or sometimes through the vents.
  • Modern Porsche models may trigger coolant level warnings or engine temperature alerts when coolant loss occurs.

Why Replacement Matters:
  • Prevents coolant leaks that can lead to low coolant levels and system pressure loss.
  • Helps avoid engine overheating, which can cause serious and expensive engine damage.
  • Restores reliable cabin heating, since proper coolant flow is needed to supply the heater core.
  • Protects the cooling system overall, reducing stress on hoses, seals, and other cooling components caused by leaks or air entering the system.
  • Maintains safe, stable engine operation, especially under load or long driving conditions.

About Engine Block Hoses

Engine Block Coolant Hoses – Front Engine Porsche Models | Reliable Cooling for Peak Performance

Engine block coolant hoses are critical to maintaining stable engine temperatures and preventing overheating in your Porsche’s front-engine cooling system. These hoses circulate coolant between the engine block, radiator, and heater core, ensuring consistent temperature regulation and efficient heat dissipation — essential for performance, reliability, and longevity.

At Design911, we supply a complete selection of genuine and manufacturer-quality engine block coolant hoses for front-engine Porsche models, including the transaxle models, Cayenne, Panamera, and Macan. Each hose is precisely engineered for a perfect fit and superior heat resistance, offering the same durability, flexibility, and performance as factory-installed components.

What Do Engine Block Coolant Hoses Do?

Coolant hoses in the engine block are responsible for transferring coolant throughout the engine’s cooling circuit. Their main functions include:

  • Carrying coolant between the radiator, water pump, and engine block.
  • Regulating engine temperature for efficient performance.
  • Maintaining system pressure within the cooling system.
  • Preventing heat build-up that can lead to overheating or gasket failure.

Properly functioning coolant hoses are essential for ensuring your Porsche’s front-mounted engine operates within optimal temperature ranges — especially during heavy use or long drives.

Why Do Engine Block Coolant Hoses Fail?

Due to constant exposure to heat, pressure, and coolant chemicals, these hoses naturally degrade over time. Common causes of failure include:

  • Heat damage from prolonged exposure to high engine temperatures.
  • Rubber deterioration or cracking from age and coolant corrosion.
  • Leaks at joints or clamps due to pressure fluctuations.
  • Swelling or soft spots from internal chemical breakdown.
  • Mechanical abrasion from contact with nearby components.

Symptoms of failing hoses include visible coolant leaks, overheating, low coolant levels, or a strong coolant smell from the engine bay.

Why Replace Faulty Engine Block Coolant Hoses?

A leaking or weakened hose can cause serious cooling system failures, including overheating and engine damage. Replacing old or brittle hoses ensures reliable coolant circulation and safeguards your Porsche’s engine performance.

Benefits of replacement include:

  • Restored cooling efficiency and pressure control.
  • Prevention of leaks and overheating.
  • Improved long-term reliability and system safety.
  • Manufacturer-quality materials for perfect fit and heat resistance.

All replacement hoses in this range are constructed using reinforced, high-grade rubber compounds that meet or exceed factory standards, ensuring durability and dependability in all driving conditions.
