What This Product Does

The upper radiator hose provides a passage for coolant between the cylinder head and radiator. Keeping this connection intact allows coolant to circulate through the cooling circuit without escaping through a damaged hose or leaking joint. The hose forms part of the system; it does not replace the radiator, thermostat or water pump.

Functions

• Connects the cylinder-head coolant outlet with the radiator.
• Carries coolant through the upper radiator connection.
• Maintains a contained coolant path when correctly fitted with sound connections.
  
  

Technical Details

• Brand: OE Match.
• Supplied part reference: 94410623911.
• Installation position: upper radiator-to-cylinder-head connection.
  
  

Symptoms of Fault

• Moisture or coolant drips around either hose connection.
• Dried deposits at the radiator neck or hose ends.
• A sweet coolant odour near the engine bay.
• Coolant level falling between checks.
• Visible splitting, swelling or unusually soft areas.
• Leakage that becomes apparent after a hot run.
• A temperature reading that rises above normal.
• Gurgling associated with coolant loss or trapped air.
  
  

These signs can also originate elsewhere in the cooling system. Inspect the hose and its connections before deciding which component needs replacement.

Why Replacement Matters

Heat cycles and age can weaken a hose or its connections, allowing minor seepage to develop into more substantial coolant loss. Renewing a deteriorated hose addresses that damaged section of the circuit. Examine the adjoining clamps and connection surfaces at the same time, as worn supporting components can leave a new hose joint leaking.

FAQs

How can a suspected leak be located?
A cooling-system pressure test can help identify seepage at the hose, its joints or another component.

Should the clamps be checked during replacement?
Yes. Inspect their condition and retention, and renew damaged or weakened clamps where necessary.

Why might leakage appear only when hot?
Operating temperature and pressure can expose a weakened hose or joint that remains dry when cold.

Does overheating prove this hose has failed?
No. Confirm the source of coolant loss and inspect the wider cooling circuit before replacing parts.
