Expansion Tank Hose - E34 525i M20 (1989-1990) - 11531720524

This original / Genuine BMW coolant hose is the return line running from the engine to the expansion tank / radiator on the 1989-1990 model E34 525i, which used the earlier M20 2.5 liter engine. 

There is one of these hoses on every '89 and '90 model 525i, and it's a common failure point. Replacing this hose with an authentic BMW part ensures you get the perfect fitment and longest lifespan. We often sell aftermarket or OEM replacements, but due to supply and discontinuations, the Genuine BMW hose is often the only one available for classic 5 series models such as the 89-90 525i.
