Discover a Range Of Aftermarket Overflow Tanks & Bottles in Australia!

While radiator overflow bottles are a relatively simple component of any car, they help prevent rust from developing in your car's cooling system. As a result, a quality radiator overflow bottle can save you a lot of money.

At Machter, we understand the importance of every part of your car’s cooling system, from the oil cooler assembly right through to your car’s radiator overflow tank. That’s why we have worked hard to create and source a range of radiator overflow bottle options for you to choose from, ensuring you can find one to suit your needs and budget.

Why Are Radiator Overflow Bottles So Important for Your Cooling System?

As your engine coolant absorbs the heat from the engine, it expands and creates pressure in your car’s cooling system. If the maximum ideal operating pressure is exceeded, overflow fluid moves into the coolant overflow bottle. Without a radiator overflow or coolant expansion bottle, things can quickly go wrong.

Unfortunately, as with everything in your car, your radiator overflow tank does wear out over time. Then you can expect to be dealing with leaks and an overheating engine to say the least. Therefore, a far less expensive option is to instead regularly check any radiator overflow bottles and replace them with an affordable and durable aftermarket overflow bottle option from Machter! Designed to withstand the pressure of regular driving and to suit a range of makes and models, buying one of our radiator overflow tanks from our Australian stores is one of the best things you can ever do.
