BMW Auxiliary Coolant Reservoir Hose E60 / E66 / F20 , BMW Coolant Hose
The auxiliary-reservoir hose plays a key role in BMW cooling systems. It links the main (radiator) tank to the auxiliary/expansion reservoir, letting coolant circulate and keeping the engine at its correct operating temperature. Its primary job is to carry coolant from the main tank to the auxiliary reservoir and, when needed, return it to the main tank. This exchange maintains pressure balance and prevents the coolant from boiling over under high temperatures. On models such as the BMW 5 Series, the hose is engineered to withstand specific pressure levels to ensure the entire cooling system runs reliably.
