Ensure optimal radiator performance with a radiator expansion bottle from Masterparts.


The coolant in your engine is essential for a successful operation of your heat transfer. It expands as your engine heats up during the combustion process and your car has therefore been installed with a radiator expansion bottle.


Also known as an expansion tank or coolant reservoir, this cooling system part provides an extra space for the coolant. With a properly working expansion tank, your radiator is always full even if the coolant inside it rises and falls.
