What This Product Does:
- Transports hot engine coolant through the heater circuit.
- Supplies coolant to the heater core or heater pump, enabling cabin heating.
- Helps maintain continuous coolant circulation within the cooling system.
- Provides a flexible, heat-resistant connection that accommodates engine movement and thermal expansion.
- Coolant may seep or drip from cracks in the hose or at the connection points, leaving wet stains or dried residue.
- A leaking heater hose can cause gradual coolant loss, requiring frequent topping up.
- If coolant flow to the heater core is reduced, the heater may blow lukewarm or cold air.
- Coolant loss from the heater circuit can reduce cooling efficiency and contribute to overheating.
- A sweet odor in the engine bay or cabin is a common sign of a heater hose leak.
- Signs include cracking or splitting, swelling or bulging, hardened or brittle rubber, soft spots, coolant staining.
- Low coolant warnings may appear if the hose begins to fail.
Why Replacement Matters:
- Prevents coolant leaks that can lead to low coolant levels and loss of system pressure.
- Maintains reliable cabin heating, since the heater core depends on proper coolant flow.
- Helps avoid engine overheating, as coolant loss reduces cooling system efficiency.
- Restores proper coolant circulation, ensuring stable engine operating temperatures.
- Protects surrounding components, because leaking coolant can damage sensors, wiring, and other engine bay parts.

Information
Coolant / Heater pipe, for Left Hand Drive only
The Genuine Porsche 92857410603 coolant / heater pipe is an OE cooling and heater system pipe for Left Hand Drive Porsche 928 1978–1995 models. It helps route coolant through the heater circuit, supporting correct cabin heater operation and cooling system function. Ideal for replacing a leaking, corroded or damaged original pipe while maintaining Genuine Porsche fitment and quality.
Fits:
for LHD (Left hand drive) cars only
Porsche 928 1978 - 1995
Diagram ref no 5
This part is specifically for Left Hand Drive (LHD) Porsche 928 applications.
What This Part Does / Functions
• Routes coolant through the heater circuit
• Connects part of the engine cooling system to the cabin heater system
• Supports correct coolant flow for heater operation
• Helps maintain proper engine cooling system circulation
• Replaces a corroded, damaged, leaking or blocked original pipe
• Helps prevent coolant loss from the heater pipe area
• Provides correct Genuine Porsche fitment for LHD vehicles
• Maintains the factory coolant and heater pipe layout.
Why Replace This Part?
Coolant and heater pipes are exposed to coolant, heat cycles, pressure, corrosion, vibration and age-related deterioration. Over time, the original pipe may corrode, weaken, leak or become restricted. A leaking heater pipe can cause coolant loss, overheating risk, heater performance issues and coolant smell around the vehicle. Replacing it with a Genuine Porsche coolant / heater pipe helps restore the correct factory coolant routing and reliable heater system operation.
Common Symptoms of a Faulty Coolant / Heater Pipe
• Coolant leak from the heater pipe area
• Low coolant level warning or regular coolant top-ups
• Sweet coolant smell from the engine bay or cabin area
• Reduced cabin heater performance
• Visible corrosion or damage on the pipe
• Coolant residue around pipe connections
• Overheating caused by coolant loss
• Pipe damage found during cooling system inspection.
When to Replace
• This Part If the original pipe is leaking, corroded or damaged
• During heater hose or heater valve replacement
• During cooling system overhaul
• If coolant loss is traced to the heater pipe circuit
• When restoring the heater system on a Porsche 928
• If the pipe has become blocked or restricted
• During engine bay restoration
• When replacing aged cooling system components with Genuine Porsche parts.
Where It Fits on the Car
This pipe fits within the coolant / heater circuit on Left Hand Drive Porsche 928 models. It forms part of the coolant routing between the engine cooling system and cabin heater system.
Correct installation is important to prevent coolant leaks, maintain heater operation and preserve the original Porsche 928 cooling system layout.
