Frequently Asked Questions

6 common questions answered

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

These symptoms can indicate depleted coolant or a leak, so a pressure test is important. Do not open the cooling system when it is hot or under pressure; checking it is done cold. A continuing drop in level should be inspected rather than repeatedly topped off.

  • Temperature gauge running higher than usual
  • Sweet smell or puddle beneath 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 SL-Class?The service drains and refills the coolant, pressure-tests the system, and inspects the hoses, cap, radiator, and water pump area.

The replacement coolant is the type and concentration the manufacturer specifies for this vehicle. The pressure test helps identify leaks, while the component inspection helps determine whether additional repair is needed. The system should be checked cold because it can remain hot and pressurized after driving.

  • Drain and refill with manufacturer-specified coolant
  • Cooling-system pressure test for leaks
  • Inspection of hoses, cap, radiator, and water pump area
How often should the coolant in a 2017 Mercedes-Benz SL-Class be changed?The manufacturer's published maintenance schedule for this vehicle settles when coolant should be flushed or replaced.

Coolant condition can also be tested during a service visit between scheduled points. That helps distinguish a routine maintenance need from a leak or another condition requiring attention. A service advisor can use the vehicle's maintenance schedule and the test results to guide the next step.

  • Follow the manufacturer’s maintenance schedule
  • Test coolant condition during an interim service visit
  • Investigate any recurring loss of coolant
What kind of coolant does a 2017 Mercedes-Benz SL-Class use?The manufacturer specifies the coolant type for this vehicle, and that specification should guide the service.

Coolants are not interchangeable, so selecting fluid by convenience can be inappropriate. Colour is not a reliable guide to what is in the bottle or whether it meets the vehicle's requirements. Mercedes-Benz of Lynnfield can service the system using the manufacturer's specified coolant type and concentration.

  • Use the manufacturer-specified coolant type
  • Do not treat coolant colours as interchangeable identifiers
  • Have the system serviced by the vehicle’s requirements
Can I just top off the coolant in a 2017 Mercedes-Benz SL-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 vehicle has a leak rather than normal coolant consumption. The system is under pressure and hot after running, so checking it is done cold. A pressure test and inspection can determine whether the condition calls for scheduled service or repair.

  • Adding coolant does not replenish depleted additives
  • Repeated level loss calls for leak inspection
  • Check the system only when it is cold
