2024 Mercedes-Benz GLS-Class Coolant: Specs & Service

The 2024 Mercedes-Benz GLS-Class is a premium all-wheel-drive SUV with a 3.0 to 4.0-liter engine range, automatic nine-speed transmission and towing capacity up to 7,700 pounds. At Park Place Motorcars Arlington in Arlington, TX, coolant service helps keep its cooling system operating as designed. The service includes draining and refilling the coolant with the type and concentration specified by Mercedes-Benz, pressure-testing the system for leaks, and inspecting key components. Coolant additives protect aluminum and gasket surfaces as they circulate, but those additives deplete over time even when the vehicle still appears to cool normally. Booking a visit helps distinguish coolant condition that calls for service from a leak that needs repair.

What a coolant service on a 2024 Mercedes-Benz GLS-Class involves

A coolant service begins with draining the existing coolant and refilling the system with the coolant type and concentration the manufacturer specifies for this vehicle. Using the specified coolant helps maintain the protection intended for the cooling system and its aluminum and gasket surfaces. The system is then pressure-tested for leaks. That test can help identify a condition that a simple fluid-level check cannot, including a leak that may be allowing the reservoir level to fall.

Alongside the fluid service and pressure test, the technician inspects the hoses, the cap, the radiator and the area around the water pump. These checks look for signs that the cooling system needs attention beyond a routine drain and refill. A sweet smell, visible residue or a puddle can make the inspection especially important. Because the 2024 Mercedes-Benz GLS-Class is available with engines ranging from 3.0 to 4.0 liters and produces 375 to 510 horsepower across its trims, maintaining the system's condition supports dependable temperature control. Schedule service at Park Place Motorcars Arlington for a cooling-system evaluation.

Why coolant condition matters on a 2024 Mercedes-Benz GLS-Class

Coolant does more than transfer heat away from the engine. Its additive package helps protect the aluminum components and gasket surfaces inside the cooling system from corrosion. Those additives deplete on a timetable of their own, even while the coolant may still look like coolant and continue moving heat. That is why condition should be judged through the appropriate service process and the manufacturer's maintenance schedule rather than appearance alone.

The 2024 Mercedes-Benz GLS-Class uses an all-wheel-drive powertrain and an automatic nine-speed transmission, with engine output ranging from 375 to 510 horsepower across the two trims. Keeping the cooling system in suitable condition supports the temperature control required by that powertrain, especially when the SUV is carrying passengers, hauling cargo or towing. If the temperature gauge runs higher than usual, the reservoir looks low, or the coolant appears rusty or cloudy, arrange an inspection. A pressure test helps separate a service need from a leak that requires repair.

Cooling system service at Park Place Motorcars Arlington

Park Place Motorcars Arlington provides coolant service for drivers of the 2024 Mercedes-Benz GLS-Class in Arlington, TX. The visit focuses on the condition of the coolant and the integrity of the cooling system rather than relying on appearance alone. The technician drains and refills the coolant using the manufacturer's specified type and concentration, pressure-tests the system for leaks, and inspects the hoses, cap, radiator and water pump area.

That combination matters because topping off the reservoir can restore a level without restoring the coolant's depleted additive package. It also does not explain why a level is low. A pressure test and component inspection help determine whether the vehicle needs coolant service or whether a leak needs repair. If you notice a sweet smell, a puddle beneath the front of the SUV, a higher-than-usual temperature gauge reading, or coolant that looks rusty or cloudy, schedule service.
