6 common questions answered
What are the signs a 2023 Mercedes-Benz GLS-Class needs a coolant service?Common signs include a higher-than-usual temperature gauge, a sweet smell, or coolant that looks rusty, cloudy, or low.
A puddle under the front of the SUV can also point to a leak. The system should be checked cold because it is hot and pressurized after operation. A service visit can test coolant condition and system pressure, helping distinguish depleted additives from a repair issue.
- Temperature gauge running higher than usual
- Sweet smell or a puddle under 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 a manufacturer-specified drain and refill, a pressure test for leaks, and an inspection of key cooling-system components.
The refill uses the coolant type and concentration the manufacturer specifies for this vehicle. The inspection covers the hoses, cap, radiator, and water pump area. Together, these steps evaluate both coolant condition and the system’s ability to hold pressure.
- Drain and refill with the specified coolant
- Pressure test of the cooling system
- 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 maintenance schedule settles when coolant service is due for a 2023 Mercedes-Benz GLS-Class, with condition testing available during a service visit between scheduled points.
No mileage or time interval should be assumed without following the vehicle’s manufacturer schedule. Coolant additives can deplete while the fluid still appears to cool normally, so appearance alone does not determine condition. A service visit can also identify whether a falling level reflects a leak that needs repair.
- Follow the manufacturer’s maintenance schedule
- Have coolant condition tested between scheduled points
- Investigate any repeated drop in coolant level
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 coolant products should not be treated as interchangeable.
Colour is not a reliable guide to what is in the bottle, so fluid selection should follow the vehicle’s manufacturer specification rather than appearance. The correct concentration also matters during a drain and refill. Mercedes-Benz of Tampa can evaluate the fluid and refill the system according to the vehicle’s requirements.
- Use the manufacturer-specified coolant type
- Do not assume different coolant products are interchangeable
- Do not use colour alone to identify coolant
Can I just top off the coolant in a 2023 Mercedes-Benz GLS-Class?Topping off restores the coolant level but does not restore the depleted additive package, and a level that keeps dropping points to a leak that needs inspection.
Adding fluid may temporarily bring the reservoir to the proper level, but it does not replace a complete coolant service or pressure test. Never open the cooling system when it is hot or pressurized; checking it should be done cold. Book an inspection if the level falls again or other warning signs appear.
- Top-off restores level only
- Repeated level loss may indicate a leak
- Check the system cold, not after running
