Detailed Description

SKP SK121198 is an engine coolant overflow hose made for compatible Volkswagen Jetta applications from 2001 through 2005. It serves as part of the cooling system’s overflow path, helping route excess coolant as the system expands and contracts with temperature changes. When the original hose becomes brittle, soft, or damaged, this replacement restores the intended coolant transfer path and helps maintain a sealed cooling circuit. The SK121198 part number is useful when matching the correct hose for service work on the Volkswagen Jetta cooling system.

Common Issues This Part May Address

• Coolant seepage from a cracked overflow hose.
• Loss of flexibility in an aging cooling hose.
• Damaged or split hose connections in the overflow line.
• Improper coolant routing caused by a failed hose.
• Service replacement for worn factory-style cooling components.

Installation Notes and Tips

Verify the vehicle’s model year and cooling-system hose routing before ordering. Compare the original hose shape and connection points to SK121198 to confirm application match. Inspect adjoining hoses and fittings for wear during installation so the cooling system can be serviced as a complete assembly if needed.
