In order to properly maintain your 2009 Mercedes C300, it will require a specific blue concentrate 50/50 coolant and antifreeze. This coolant is commonly used in Mercedes vehicles from this era, so it should be relatively easy to find. With a coolant capacity of 5.3 US quarts, you will need to purchase at least a one-gallon jug and possibly an additional smaller bottle or two to ensure you have enough to completely refill it. The total cost for the necessary fluids will likely range between $30 and $45, which is more affordable compared to other Mercedes models due to the smaller capacity of the C300.
The Mercedes-Benz C300 of 2009 requires the use of OEM engine coolant specific to the model.
