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.
