A Quick Look at Porsche
Porsche information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where Porsche is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons people replace these parts include maintaining originality, keeping factory specification, and choosing the latest genuine revisions for peace of mind.
- Common real-world issues behind many Porsche repairs are age and mileage: oil leaks, cooling system fatigue, brake and suspension wear, corrosion and electrical faults from moisture or heat cycling.
- Before ordering, confirm part numbers against VIN or option/PR codes, especially for safety‑critical or complex components.
- When upgrading, decide whether you want pure originality or performance changes, as some aftermarket options may suit specific goals better than genuine.
- For bigger jobs, replace related seals, hardware and consumables at the same time to avoid repeat labour and compatibility issues.
- Where available, follow the manufacturer’s fitting and bedding‑in guidance to get the best performance and longevity.

- Follow any recommended bedding-in procedure and consider replacing discs, pads, sensors and fitting hardware together where advised.
Clothing & Gifts — Porsche-themed clothing and gifts let owners and enthusiasts show their passion off the road, or make ideal presents for fans of the marque. Common symptoms include: Items may become worn, faded, damaged or go out of style, prompting replacement with newer designs.

Genuine Porsche Original Equipment (OE) heater coolant return hose that connects between the engine cooling circuit and the heater return line, ensuring proper coolant flow through the heater core and back to the engine cooling system.
Fits:
Porsche 996 Carrera 2002 - 2005 Tiptronic Gearbox only
Porsche 997.1 3.6L / 3.8L 2004 - 2008
Porsche 997.1 Turbo / GT2 2007 - 2009

This hose ensures an unobstructed and secure channel for coolant returning from the vehicle’s heater core to the engine cooling loop, playing a vital role in passenger cabin heating and overall engine thermal regulation. Its precise fit and correct routing are essential to avoid bypassing or pinching, which could otherwise lead to heater inefficiency or premature failure.
Installed between the heater core outlet and the engine’s return fitting, this hose:
• Transports heated coolant from the heater core back to the engine cooling system
• Maintains correct flow and pressure balance within the cooling circuit
• Operates under high temperatures and multiple thermal cycles
• Interfaces with factory-specified clamps and hose connections
Because it is made to OE specification, the hose ensures proper sealing and routing that matches the original Porsche design.
A cooling system hose that has become brittle, cracked, swollen, or porous can leak or restrict flow, leading to reduced heating performance, coolant loss, and potential engine overheating. Because the heater return hose carries pressurised coolant across temperature extremes, degradation over time is typical. Replacing it with a Genuine Porsche OE part ensures correct material performance and sealing, helping preserve cooling efficiency and prevent unexpected failures.
When to replace:
• Visible cracks, swelling, or soft spots
• Coolant leaks around the hose ends
• Heater blowing cold air, indicating poor coolant flow
• Cooling system overhaul or heater core service
• Preventive maintenance on high-mile vehicles
