Condition

Original used BMW component with visible age- and use-related wear, including:

• Dirt and storage marks
• Surface discolouration
• Light scuffs and cosmetic wear
• Marks around the hose connections
• Normal ageing of the rubber
• Impressions from previously installed hose clamps

The hose has not been pressure-tested. Its internal reinforcement and long-term serviceability cannot be guaranteed.

Because this is a used cooling-system component, the buyer or installer must carefully inspect the hose for hardening, softness, swelling, cracking, internal deterioration and damage around both connections before installation.

Supplied exactly as shown in the photographs.

Included

• One original BMW upper radiator hose

Hose clamps, coolant, thermostat housing, radiator and other cooling-system components are not included.

Important quantity information

One upper radiator hose is used per vehicle.

This listing includes one hose, which is sufficient for one compatible vehicle.

Installation recommendation

Before installation:

• Clean the inside and outside of the hose
• Check the rubber for cracks, hardening, swelling and soft areas
• Inspect both hose ends for clamp damage
• Confirm that the internal reinforcement has not separated
• Compare the shape and dimensions with the original hose
• Use suitable hose clamps
• Refill the system with the correct coolant mixture
• Bleed the cooling system according to BMW specifications
• Check the complete system for leaks after reaching operating temperature

Replacement with a new hose is recommended if any deterioration or uncertainty is found during inspection. Installation should preferably be performed by someone familiar with classic BMW M30 cooling systems.
