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. Rubber breaks down and can split and does not hold up well to other chemicals such as engine oil or fuel. The plastic clips and metal retaining clamps are strong but are only 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 less than a year 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 330i cooling hose manufactured by Rein Automotive (CRP) - a front-line supplier of original equipment, private label, and in-house engineered replacement parts. Rein replacement products meet or exceed all of BMW's original design, fitment, and performance requirements and they carry out testing with ISO and German TUV for quality control. Rein 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.
