Constructed from heat-resistant materials designed to withstand continuous exposure to engine bay temperatures, pressure fluctuations and coolant vapours, the hose plays a vital role in maintaining proper heater system performance and climate control functionality.
What This Product Does:
- Connects the heater disc valve to the vehicle's heating system.
- Allows the controlled flow of coolant or heated air through the heater circuit.
- Supports efficient cabin heating performance.
- Helps regulate interior temperature control.
- Maintains the integrity of the heating and ventilation system.
- Prevents coolant or air leakage from the heater circuit.
- Contributes to overall HVAC system efficiency and reliability.
Symptoms Of Wear Or Failure:
- Coolant leaks within the engine bay.
- Loss of coolant without obvious external leaks.
- Reduced cabin heating performance.
- Heater producing inconsistent temperatures.
- Sweet coolant smell inside or around the vehicle.
- Visible cracking, splitting or swelling of the hose.
- Soft, brittle or deteriorated hose material.
- Moisture or coolant residue around hose connections.
- Engine overheating caused by coolant system leaks.
Why Replacement Matters:
- Heater hoses operate in demanding conditions and are constantly exposed to heat, pressure changes, coolant chemicals and environmental ageing. Over time, rubber hoses can harden, crack, swell or weaken, increasing the risk of leaks and system failure.
- A damaged heater hose can lead to coolant loss, poor cabin heating performance and reduced cooling system efficiency. If coolant loss becomes severe, engine overheating may occur, potentially resulting in costly engine damage. Even small leaks can worsen over time and affect both comfort and reliability.
- Replacing a worn disc valve heater hose restores proper coolant circulation through the heating system, prevents leaks and helps maintain reliable climate control performance. An OE Match replacement provides factory-style fitment, dependable durability and long service life, helping preserve the efficiency and reliability of your Porsche's heating and cooling systems.

Proper hose retention is essential for maintaining coolant flow, heating performance and overall engine cooling system reliability.
What This Product Does:
- Secures heater hoses to pipes, fittings and cooling system components.
- Maintains a leak-free coolant system connection.
- Provides consistent clamping force under varying temperatures.
- Prevents hose movement caused by vibration and pressure changes.
- Supports efficient coolant circulation through the heating system.
- Helps maintain correct cabin heating performance.
- Contributes to overall cooling system reliability and safety.
Symptoms Of Wear Or Failure:
- Coolant leaks around heater hose connections.
- Visible corrosion or rust on the clamp.
- Loose or slipping heater hoses.
- Coolant residue around hose fittings.
- Reduced heater performance due to coolant loss.
- Sweet coolant odour from the engine bay.
- Low coolant level warnings.
- Overheating concerns caused by coolant leakage.
- Visible clamp deformation or loss of tension.
Why Replacement Matters:
- Heater hose clamps are exposed to continual heat cycles, moisture, coolant chemicals and engine vibration. Over time, corrosion, metal fatigue or loss of clamping tension can reduce their ability to maintain a secure seal between hoses and cooling system components.
- A failing hose clamp can allow coolant to escape, leading to reduced heater efficiency, cooling system pressure loss and potential engine overheating. Even minor coolant leaks can worsen over time, increasing the risk of damage to cooling system components and resulting in costly repairs.
- Replacing a worn or damaged heater hose clamp restores proper hose retention, prevents coolant leaks and helps maintain the efficiency and reliability of the cooling and heating systems. An OE Match replacement provides factory-style fitment, dependable clamping performance and long-term durability, ensuring reliable operation of your Porsche cooling system.

Blower Hose in engine bay, appox 1 meter long, 60mm diameter.
An OE Match blower hose made from black outer material with an aluminium inner structure, designed to channel heated air within the engine bay heating system of Porsche 911 models.
Fits:
Porsche 911 1975 - 1983
Also used on Pre >>1973 911's in the heater system
Diagram ref no 13
This OE Match Blower Hose is a high-quality replacement component designed to replicate the original Porsche heater hose used in classic air-cooled 911 models. Installed in the engine bay, this hose connects the blower motor to the heat exchanger, enabling the transfer of warm air into the vehicle’s heating system.
This hose, approximately 60 mm in diameter and approximately 1 meter long, is designed for proper routing and fit within the limited space of the engine compartment. It plays a crucial role in maintaining proper cabin heating performance, especially in colder driving conditions.
This blower hose channels heated air from the engine-mounted blower to the heat exchangers, ensuring warm air is properly distributed through the vehicle’s heating system.
Function
• Transfers heated air from blower to heat exchanger
• Maintains consistent airflow within the heating system
• Withstands high engine bay temperatures
• Flexible design allows correct routing and installation
• Supports effective cabin heating performance
Over time, blower hoses can become brittle, cracked, or collapsed due to prolonged exposure to heat and age. This can lead to reduced airflow, poor heating performance, and potential heat loss within the system. Replacing a worn hose ensures efficient heat transfer, improves cabin comfort, and maintains proper operation of the vehicle’s heating system.
When to replace
• Visible cracks, splits, or deterioration
• Reduced or inconsistent cabin heating
• Hose becoming brittle or collapsing under heat
• During engine bay or heating system restoration
• Signs of air leaks or disconnected ducting
