Mercedes Sprinter Lower Radiator Hose (3-Way) – OEM Replacement (2010+) | #9065013682

The lower radiator hose is the return leg of your Sprinter's cooling circuit — and on 2010+ OM642 models, it's a 3-way hose, meaning it manages coolant flow to multiple points simultaneously. When this hose softens, cracks, or collapses internally, your entire cooling system pays the price. This OEM-spec 3-way replacement restores proper coolant distribution and keeps your engine in its optimal temperature range.

What This Part Does

Unlike a standard two-connection radiator hose, this 3-way hose carries cooled coolant from the radiator outlet and distributes it to multiple engine cooling circuits — including the water pump and auxiliary cooling lines. Getting this hose wrong in either spec or fitment disrupts coolant flow to critical areas of the engine, which is why using the correct part number matters.

When to Replace It

Replace this hose if you notice coolant loss with no visible external leak, rising engine temperatures, or a hose that feels soft or collapses when squeezed. It's also a smart preventive replacement during any water pump, thermostat, or radiator service — especially on high-mileage vans where rubber has been subjected to years of heat cycling.
