This coolant hose is a OEM replacement for your F10 528i and E89 Z4 28i with the N20 engine. 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 cooling system hoses as a preventative measure before they fail in order to save you from further headaches and expenses.
This is a coolant hose manufactured by Vaico. This part has a two year warranty.
