Lower Radiator Hose to Inlet Pipe, Rein - E82 135i, E9X 335i, E84 X1 35i, E89 Z4 35i

This Lower Radiator Hose is a OEM replacement for your E82 135i, E9X 335i with the N54 engine. This hose is used only on cars with automatic transmission and runs from the radiator to the coolant inlet pipe on the engine block. Not all cars have this hose that bypasses the thermostat and water pump.

Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age and can eventually fail. The plastic clips and metal retaining clamps on hoses are stronger than before but they are only really good for one-time use. Once removed they never seem to seal as well, leading to a leak soon after. A new hose is recommended any time the old one is disconnected (unless it's only a couple of years old). We highly recommend that you replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

This is a radiator hose manufactured by Rein (CRP) Automotive - an original supplier to BMW for many engine components. As an OEM, Rein meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
