T25 Water Hose - Water Pipe To Breather Valve - 1985-92 - 1.9 Waterboxer

Replacement coolant feed hose connecting the water pipe to the breather valve on VW T3/T25 1.9 waterboxer models. This hose forms part of the main cooling circuit and carries coolant from the engine cooling system towards the radiator feed line while also assisting with correct coolant bleeding and air removal.

Over time the original rubber hoses can become soft, cracked or internally weakened due to age and heat cycles. A failing coolant hose can lead to coolant leaks, overheating, poor coolant circulation or difficulty bleeding the cooling system correctly. Replacing worn hoses is essential for maintaining reliable cooling system performance on watercooled T3 models.

This hose is fitted to non-Syncro T3/T25 models equipped with 1.9 litre waterboxer petrol engines from chassis number 24-F-060001 onwards.
