Diagram Ref No 36
This coolant pipe forms part of the cooling circuit associated with the engine compressor system, providing a secure route for coolant between the relevant components. It must safely contain and transport coolant while the system is exposed to heat, pressure, vibration and repeated temperature changes.
Over time, coolant pipes, seals and connection points can deteriorate. Corrosion, physical damage, ageing seals or repeated thermal cycling may cause coolant seepage or more substantial leakage. Even a relatively minor leak can gradually reduce the coolant level and compromise cooling-system performance.
Replacing a damaged or leaking pipe with this OE Match Coolant Pipe helps restore a sealed cooling circuit, maintain dependable coolant flow and reduce the risk of overheating or associated component damage.
What This Product Does:
- Carries coolant through the relevant cooling circuit.
- Provides coolant routing for the engine compressor system where specified.
- Connects associated cooling-system components.
- Contains hot, pressurised coolant.
- Helps maintain a sealed coolant circuit.
- Supports correct coolant circulation.
- Helps regulate component operating temperatures.
- Supports effective heat transfer.
- Helps prevent coolant loss when correctly installed and sealed.
- Works alongside associated hoses, pipes, pumps and cooling components.
- Replaces a leaking, corroded or damaged coolant pipe.
- Provides a Porsche replacement component for compatible applications.
- Visible coolant leakage.
- Low coolant warning.
- Coolant level repeatedly dropping.
- Increasing need to top up the coolant.
- Coolant smell from the engine compartment.
- Wetness around the coolant pipe.
- Leakage around pipe connections.
- Dried or crystallised coolant residue.
- Visible corrosion or deterioration.
- Damaged or distorted pipework.
- Leakage around seals or O-rings.
- Steam from the engine compartment.
- Engine temperature higher than normal.
- Unusual temperature fluctuations.
- Engine overheating.
- Coolant collecting underneath the vehicle.
Why Replacement Matters:
- The cooling system depends on maintaining coolant within a sealed circuit.
- A leaking coolant pipe allows the system level to fall. Initially, the leak may be small enough to appear only as dried residue or an occasional need to top up the coolant. However, deterioration can progress until a substantially larger leak develops.
- Replacing a confirmed faulty OE Match Coolant Pipe helps restore system integrity before a minor coolant leak becomes a more serious problem.

This hose carries returning coolant through its designated section of the cooling circuit. A sound hose and correctly sealed connections help retain coolant as it circulates through the system. It is a replacement return line, rather than an expansion tank, cap or level sender.
Functions
- Provides a passage for returning coolant.
- Contains coolant within the return circuit.
- Connects the associated cooling-system components.
Technical Details
- Part reference: 97010650101.
- Component identification: coolant hose, return line.
- Supplied engine/model identifiers: 4620, 4640, CWAA and CXNA.
- Application: specified 3.6L V6 Panamera and Panamera 4 variants.
Symptoms of Fault
- Moisture or dried coolant deposits at the connections.
- A sweet odour following a journey.
- A gradually falling coolant level or recurring warning.
- Cracking near a clamp or connection.
- Swollen sections or unusually soft areas.
- Seepage that appears only when the system is hot.
- Staining beneath the engine or on the undertray.
- Gurgling or an unexpected temperature increase.
Why Replacement Matters
Renewing a deteriorated return hose addresses a potential source of coolant loss. Repeated heating and cooling, ageing and contamination can weaken hoses or their connections. Inspect neighbouring fittings, clips and sealing surfaces during the repair, since replacing the hose alone will not resolve damage elsewhere. OE Match focuses on replacement components for Porsche applications, with specification and fitment checks forming part of its development process.
FAQs
- How can a suspected hose leak be located?
A cooling-system pressure test can help reveal seepage. Examine the hose ends and nearby connections for fresh moisture or deposits. - Why might there be no puddle?
Small amounts of escaping coolant may evaporate against hot surfaces or remain trapped above the undertray. - Should the clamps also be checked?
Yes. Inspect their condition and retention, together with the adjoining fittings, before reassembly. - Do these symptoms confirm this hose has failed?
No. Nearby pipes, seals, the pump or thermostat housing can produce similar signs, so establish the leak source first.

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.
