Lower Radiator Hose to Thermostat, Rein - F22 228i, F30 320i/328i, F32 428i with Oil Cooler

This Lower Radiator Hose is a OEM replacement for your F22 228i, F30 320i/328i, F32 428i with the N20 engine and Sport Line or High Speed Synchronization (same components). This lower hose also has an extension over to the auxiliary radiator located in the passenger wheel well. This added cooling capacity and surface area and seems to focus on improving turbo cooling.

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.
