055-121-063A Coolant Hose Water Pump to Pipe - VW Rabbit Jetta Scirocco

Coolant Hose (Water Pump to Pipe) – 055-121-063A

The 055-121-063A is an essential cooling system connector designed for early water-cooled Volkswagen engines. This molded hose features a specific design to bridge the gap between the water pump housing and the main metal coolant distribution pipe. Constructed from high-grade rubber with internal reinforcement, it is engineered to withstand high pressures and the chemical additives found in modern engine coolants.

Replacing this hose is highly recommended during water pump service or if the original rubber feels spongy or shows signs of swelling. A secure fitment ensures consistent coolant flow to the engine block, preventing overheating and protecting your Volkswagen's engine longevity.

Installation & Maintenance Tips

• Hose Clamp Selection: For the best seal, use high-quality stainless steel clamps to accommodate the rubber's expansion and contraction during heat cycles.

• Coolant System Flush: When replacing cooling hoses, it is the ideal time to flush the system and refill with the correct specification coolant to prevent internal corrosion.

• Inspect the Metal Pipe: Check the end of the metal distribution pipe for rust or scaling before installing the new hose; a smooth surface is required for a proper seal.
