6 common questions answered
What are the signs a 2023 Mercedes-Benz GLS-Class needs a coolant service?Higher-than-usual temperature readings, a sweet smell, a puddle, or rusty, cloudy, or low coolant can indicate that your 2023 Mercedes-Benz GLS-Class needs cooling system service.
These signs can reflect depleted coolant additives or a leak. The system should be checked cold because it is pressurized and hot after running. A service visit can test the coolant and pressure-test the system.
- 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 2023 Mercedes-Benz GLS-Class?Coolant service includes draining and refilling the system with the manufacturer-specified coolant type and concentration, pressure testing it, and inspecting key components.
The inspection covers the hoses, cap, radiator, and water pump area. These steps help identify whether the vehicle needs routine coolant maintenance or repair for a leak. Mercedes-Benz of Lynnfield can evaluate the system during a scheduled visit.
- Drain and refill with the specified coolant formulation
- Cooling-system pressure test for leaks
- Inspection of hoses, cap, radiator, and water pump area
How often should the coolant in a 2023 Mercedes-Benz GLS-Class be changed?The manufacturer's published maintenance schedule settles when coolant service should be performed on a 2023 Mercedes-Benz GLS-Class.
Coolant condition can also be tested during a service visit between scheduled points. That testing helps determine whether the additive package remains effective or whether service is appropriate sooner. A falling coolant level should be evaluated as a possible leak rather than treated as normal consumption.
- Follow the manufacturer's maintenance schedule
- Request coolant-condition testing between scheduled points
- Book an inspection if the level drops
What kind of coolant does a 2023 Mercedes-Benz GLS-Class use?The 2023 Mercedes-Benz GLS-Class uses the coolant type specified by its manufacturer, and the correct formulation should be confirmed for this vehicle.
Coolants are not interchangeable, so choosing by color can lead to an incorrect refill. Color is not a reliable guide to what is in the bottle. Mercedes-Benz of Lynnfield can use the manufacturer's specification when servicing the cooling system.
- Use the manufacturer-specified coolant type
- Do not treat different coolant formulations as interchangeable
- Do not rely on fluid color to identify compatibility
Can I just top off the coolant in a 2023 Mercedes-Benz GLS-Class?Topping off a 2023 Mercedes-Benz GLS-Class restores the fluid level but does not restore the depleted additive package or explain why the level changed.
A system that keeps losing coolant should be inspected for a leak rather than treated as normal consumption. Never open the cooling system while it is hot or pressurized; checking it is done cold. A pressure test can help identify the source of a loss.
- Topping off does not renew coolant additives
- A repeatedly low level can indicate a leak
- Check the system only when it is cold
