Frequently Asked Questions

6 common questions answered

What are the signs a 2017 Mercedes-Benz CLS-Class needs a coolant service?Common signs include a higher-than-usual temperature gauge, a sweet smell or puddle, and coolant that looks rusty, cloudy, or low.

These symptoms can point to depleted coolant or a leak in the cooling system. The system should be checked cold because it is hot and under pressure after running. A pressure test helps determine whether maintenance or repair is needed.

  • Temperature gauge running higher than usual
  • Sweet smell or puddle under the front of the vehicle
  • Rusty, cloudy, or low coolant in the reservoir
What is included in a coolant service on a 2017 Mercedes-Benz CLS-Class?The service drains and refills the coolant, pressure tests the system for leaks, and inspects the hoses, cap, radiator, and water pump area.

The refill uses the type and concentration the manufacturer specifies for this vehicle. The pressure test helps identify a leak that a fluid replacement alone would not correct. Inspection findings determine whether additional repair is needed.

  • Drain and refill with manufacturer-specified coolant
  • Cooling-system pressure test
  • Inspection of hoses, cap, radiator, and water pump area
How often should the coolant in a 2017 Mercedes-Benz CLS-Class be changed?The manufacturer publishes a maintenance schedule for this vehicle, and that schedule settles when coolant replacement is due.

The published schedule for this model year calls for flushing or replacing coolant every 36,000 miles. Coolant condition can also be tested during a service visit between those points. A test helps distinguish a scheduled service from a condition that requires attention sooner.

  • Follow the manufacturer's published schedule
  • Have coolant condition tested between scheduled points
  • Check for leaks when the level drops or symptoms appear
What kind of coolant does a 2017 Mercedes-Benz CLS-Class use?The manufacturer specifies a coolant type for this vehicle, and that specification should guide the refill.

Coolants are not interchangeable, so choosing by convenience can be unsuitable for the cooling system. Color is not a reliable guide to what is in the bottle. Mercedes-Benz of Lynnfield can use the manufacturer's specified coolant during service and inspect the system at the same visit.

  • Use the manufacturer-specified coolant type
  • Do not treat coolant colors as a reliable identification method
  • Have the system checked if fluid is mixed or uncertain
Can I just top off the coolant in a 2017 Mercedes-Benz CLS-Class?Topping off restores the coolant level but does not restore the additive package or explain why the level changed.

If the level keeps dropping, the situation indicates a leak rather than normal consumption and should be inspected. Never open a cooling system while it is hot or under pressure; checking it is done cold. A pressure test can help identify the source.

  • Adding coolant restores level only
  • Repeated level loss calls for leak inspection
  • Check the system only when it is cold
