BMW Radiator Hose - 17123413819 X3

Carries coolant from the thermostat to the radiator

The lower radiator hose on your X3 goes through severe heating and cooling cycles. This constant change in temperature wears the rubber out faster than the upper radiator hose in comparison. If you notice any unusual bulging or dry rotting on this hose we recommend immediate replacement.

Engine Coolant Bleed Hose

Radiator hoses have an important job to transport your engines coolant to and from its cooling system components. Over time they can become dry, hard, brittle, or leak which warrants a replacement. When replacing we also recommend a coolant flush and replacement to remove any possible sludge formed over time.
