VAG Vehicles 2002: Coolant Leak Troubleshooting (Solution)

Coolant leak in coolant hoses.

Cause.
Damage to the hoses from the inside. Due to the internal damage, coolant leaks through the fabric lining of the hose and emerges at the ends of the hose.

Solution:
If a coolant leak is detected at the end of a hose, only the affected hose needs to be replaced. Parts that have been contaminated by the leaking coolant must be cleaned (e.g., the coolant reservoir). After that, a leak test of the entire cooling system must be performed.
