Information
Engine to heat exchanger hose, 380mm x 60mm.
This is a high-quality replacement hot-air hose connecting the engine fan duct to the heat-exchanger in classic Porsche models. With an internal diameter of 60 mm and a length of 380 mm, this hose replicates the original specification, including the aluminium-lined construction and brown-paper exterior that Porsche used.
Fits:
Porsche 912
Porsche 911 1965-73
Engine to Heat Exchanger on the Left or Right
Fits:
Porsche 930 Turbo 1975-89
Porsche 911SC
Porsche 911 3.2L
Engine to Heat Exchanger on the right
Diagram ref no. 20
• Position on Vehicle: Engine bay, connecting the engine fan duct/air-intake housing to the heat-exchanger (or heater box) via the hose (typically on the right side).
• Cross-Reference / Alternative Numbers: 901 211 194 01 (current) supersedes and replaces 901 211 194 00.
• Material & Construction: Crafted from heat-resistant aluminium-lined hose, clad externally with the original brown-paper finish and sized to match the factory shape (60mm inner diameter, ~380mm length). Built for high-temperature engine-bay environment and correct airflow performance.
• Applications: Ideal when the original hose is cracked, delaminated, deformed, missing, or when restoring correct heating/airflow behaviour in the engine bay or passenger compartment on classic air-cooled Porsche cars.
This hot-air hose plays a vital role in engine and cabin heat management: if it's cracked, collapsed, or detached, you may experience reduced heater output, engine-bay overheating, erratic air-flow, or loss of original ducting performance. Installing a correctly specified replacement restores the original system’s performance and helps maintain correct engine and cabin temperature control.
When and why to replace:
• Visible cracking, splitting, or sagging in the old hose.
• Hose has been removed, reused too often or replaced with incorrect diameter/length.
• Heater output is weak or airflow to engine/compartment is abnormal.
• Restoring a classic 911/930 and you require original spec parts for authenticity and functionality.

What This Product Does:
- Transports hot engine coolant to and from heater system components such as the heater core or heater control valve.
- Enables the HVAC system to produce warm air for cabin heating.
- Maintains proper coolant circulation within the heater portion of 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, often leaving visible residue.
- A leaking heater hose can cause gradual coolant loss, requiring frequent topping up.
- If hot coolant cannot circulate properly through the heater core, the HVAC system may blow lukewarm or cold air.
- Coolant loss or restricted flow in the heater circuit can reduce overall cooling efficiency.
- A noticeable coolant odor in the engine bay or cabin can indicate a heater hose leak.
- Signs may include cracking or splitting, swelling or bulging, hardened or brittle rubber, coolant staining along the hose.
- Low coolant or temperature warnings may appear if leakage becomes significant.
Why Replacement Matters:
- Prevents coolant leaks that can lead to low coolant levels and loss of system pressure.
- Maintains consistent cabin heating, since the heater core depends on proper coolant flow.
- Helps prevent engine overheating, as coolant loss reduces overall cooling efficiency.
- Restores proper coolant circulation, ensuring stable engine operating temperatures.
- Protects surrounding components, because leaking coolant can damage sensors, wiring, and nearby engine parts.
