If you are noticing your radiator hoses appear to be caving in on your BMW 530i, the culprit could be a faulty radiator cap. The one small BMW radiator cap, which can be replaced for less than $20, actually regulates the pressure of your entire BMW cooling system. When your engine is running and hot, your BMW coolant expands. When the engine is cooling, your antifreeze contracts. This constant shift in temperatures requires the pressurized regulation of the coolant by a hermetically sealed radiator cap. If the cap is no longer able to perform due to age, your entire cooling system is headed for a tempestuous fate. If you'll be changing out your BMW radiator cap, remember to always replace it when the engine has sufficiently cooled.
Whether you're in the market for a Genuine BMW radiator cap, or a Mahle Behr or URO aftermarket cap, you can pick one up a la carte or pair it with one of our AAZ preferred kits. Most BMW motorists will replace multiple cooling system components at the same time because many of them pertain to the other. Our in-house kit BMW2EXPTNKKIT, has many 3 series applications and comes with the BMW expansion tank, radiator cap and engine thermostat.
