Type 25 Water Hose - Manifold To Carburettor - Right - 1.9 (DG Engines)

This replacement radiator/coolant hose connects the water port on the right-hand side of the inlet manifold to the front of the carburettor on 1900cc petrol Waterboxer engines fitted to VW Type 25 buses.
On RHD models, the right-hand side is the drivers side.

On 1.9 Waterboxer engines, this hose provides a controlled flow of coolant to the carburettor area, aiding carburettor temperature stabilisation and helping prevent icing in cold or damp conditions. Because it operates close to engine heat and fuel components, the original hose often hardens or cracks with age—leading to coolant leaks and poor drivability.

Manufactured from high-quality NBR fabric-reinforced rubber, this hose is formed to the exact original shape and specification, ensuring a perfect fit, correct routing, and long service life.

What this hose does and how it works

Coolant exits the inlet manifold through the right-hand water port and flows via this hose to the carburettor warming circuit. This gentle heat transfer helps maintain consistent fuel atomisation and smooth running, particularly during warm-up. A sound hose here is essential for leak-free operation and reliable cold-weather performance.
