Your cooling system is crucial to vehicle reliability. One small leak in the cooling system can cause catastrophic effects including permanent engine damage. The most common failure we see in cooling systems is leaking BMW 3 Series radiator hoses. While inexpensive to replace many people fail to change their BMW 3 Series radiator hoses and realize too late that their hoses have rotted away. Here at Andy's Auto Sport we have a great selection of BMW 3 Series radiator hoses for you to choose from. With hoses from all of the top manufacturers you are sure to find the perfect set to fit your application in our expansive lineup.

While rubber hoses work pretty well for a stock vehicle, if you have increased engine power then you are also making more heat in your motor. Rubber hoses tend to expand and bulge under these conditions which can cause problems on the road or on the track. Several companies offer high-performance silicone hose upgrades that are designed to with stand the increased temperatures of a high-strung motor. The silicone hoses are great at holding their shape and hold up better to the under hood heat and chemical exposure as well. If you want a great upgrade to improve reliability and add a little custom look, we strongly recommend stepping up to BMW 3 Series silicone radiator hoses.

Q: What is a radiator hose? Why buy one?
A: Radiator hoses connect your radiator to your engine, allowing coolant to pass through, but also allowing for some flexibility in order to accommodate the engine as it twists and vibrates. It is common for OEM radiator hoses to get leaks and tears from exposure to the tremendous heat and fluids that exist under the hood of your vehicle. While a stock replacement hose will work just fine as a fix, there are also fantastic upgraded units available. High-performance silicone radiator hoses feature tougher construction for improved resistance to heat and chemicals, they do not stretch and expand like rubber, and they will remain pliable for years to come unlike rubber hoses which dry out and crack. For a little extra money you can step up to far superior silicone hoses and drive with renewed confidence. In addition silicone hoses are available in an assortment of colors that will give your engine bay a great custom look.
