Description
The engine cooling system is one of the most crucial systems on your vehicle, and your expansion tank cap is responsible for keeping the coolant at a set pressure. If your expansion tank cap fails, you can be left waiting on the side of the road for a tow truck.
Symptoms of expansion tank cap failure include coolant leaks and vehicle overheating. If you are experiencing any of these symptoms, it may be time to replace your expansion tank cap.
While you are replacing your expansion tank cap, now would be the perfect time to inspect and replace other cooling system components that are starting to show their age, such as coolant hoses, the thermostat and even the water pump.
Don't forget to get some coolant, too. Euromotiv carries the correct coolant for your Mercedes-Benz to help you keep its cooling system functioning perfectly for years to come.
