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

The 2024 Mercedes-Benz GLS-Class is a large all-wheel-drive SUV with a 3.0- to 4.0-liter engine range, premium unleaded fuel requirement, and towing capability up to 7,700 pounds. At Mercedes-Benz of Draper in Draper, UT, coolant service helps keep its cooling system ready for everyday driving, hauling, and changing temperatures. The service includes draining and refilling coolant with the type and concentration specified by Mercedes-Benz, pressure-testing the system for leaks, and inspecting key components. Coolant additives gradually lose their protective properties even while the vehicle continues to run normally, so testing can identify whether service is due or whether a leak needs repair. Schedule a cooling system inspection when you notice a high temperature gauge, sweet smell, puddle, or low reservoir level.

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

Coolant service begins with draining the existing coolant from the cooling system. The system is then refilled with the coolant type and concentration the manufacturer specifies for this vehicle. This is more than a simple level check: the refill restores the fluid intended to transfer heat and protect internal surfaces.

After the refill, the system is pressure tested for leaks. Pressure testing can help distinguish coolant that has reached the end of its useful condition from a cooling-system fault that requires repair. A technician also inspects the hoses, cap, radiator, and water pump area for signs of leakage or deterioration. These checks provide useful context for the vehicle's coolant level and condition.

For a 2024 Mercedes-Benz GLS-Class, booking coolant service means having both the fluid and the system evaluated together. If the inspection identifies a leak, the next step can focus on the affected component rather than treating the issue as routine fluid service. Schedule service at Mercedes-Benz of Draper for a cooling-system evaluation.

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

Coolant does more than carry heat away from the engine. Its additive package helps protect aluminum and gasket surfaces inside the cooling system from corrosion. Those additives deplete over time on their own timetable, even when the fluid still looks like coolant and continues to circulate normally.

That is why coolant condition should be judged through the manufacturer's maintenance schedule and testing at a service visit rather than appearance alone. The 2024 Mercedes-Benz GLS-Class uses engines ranging from 3.0 to 4.0 liters, with six- to eight-cylinder configurations across the model's trims. Proper cooling-system condition supports the temperature control those powertrains need during normal operation and heavier use.

A higher-than-usual temperature gauge, sweet smell, puddle beneath the front of the SUV, or coolant that appears rusty, cloudy, or low in the reservoir deserves attention. A cooling-system test can help separate depleted coolant from a leak. If the vehicle has recently been driven, remember that the system may be hot and pressurized; checks should be performed cold.

Cooling system service at Mercedes-Benz of Draper

Mercedes-Benz of Draper provides coolant service for drivers bringing a 2024 Mercedes-Benz GLS-Class to 11548 Lone Peak Parkway in Draper, UT. The visit is designed to evaluate the condition of the coolant and the condition of the system that contains it. Draining and refilling addresses the fluid, while pressure testing and inspection look for leaks around the hoses, cap, radiator, and water pump area.

This approach matters because adding fluid alone cannot restore depleted additives or explain a level that keeps falling. A pressure test helps identify whether the vehicle needs routine coolant service or repair attention. The same evaluation can also help clarify symptoms such as a rising temperature gauge, a sweet odor, or a visible puddle.
