2025 Mercedes-Benz G-Class Coolant: Specs & Service

The 2025 Mercedes-Benz G-Class is a four-wheel-drive SUV available across gasoline and electric powertrain configurations, with up to 577 horsepower, and its cooling system supports dependable operation in varied driving conditions. Mercedes-Benz of Draper in Draper, UT, provides coolant service for drivers who want the system checked rather than relying only on the temperature gauge or reservoir level. The service includes draining and refilling the coolant with the type and concentration the manufacturer specifies, pressure-testing the system for leaks, and inspecting key components. Coolant additives deplete over time even when the fluid still appears to cool effectively, so testing helps distinguish routine maintenance from a leak that needs repair. Schedule service at Mercedes-Benz of Draper for a cooling-system check tailored to your G-Class.

What a coolant service on a 2025 Mercedes-Benz G-Class involves

A coolant service for the 2025 Mercedes-Benz G-Class begins with draining the existing coolant from the system. The replacement coolant is then added using the type and concentration the manufacturer specifies for this vehicle. Using the correct formulation matters because coolant products are not interchangeable, and the right mixture supports the system's intended protection and heat transfer.

After the refill, the system is pressure-tested for leaks. Pressure testing can help identify a cooling-system problem that a simple level check may miss. The inspection also covers the hoses, the cap, the radiator and the area around the water pump. These checks help separate coolant that has reached the point where service is appropriate from a system that is losing fluid and needs repair. If your G-Class shows a higher-than-usual temperature reading, a sweet smell or a puddle beneath the front of the vehicle, schedule service with Mercedes-Benz of Draper.

Why coolant condition matters on a 2025 Mercedes-Benz G-Class

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

The 2025 Mercedes-Benz G-Class spans six- and eight-cylinder gasoline engines from 3.0 to 4.0 liters, as well as an electric configuration, so the cooling hardware and service considerations can differ by powertrain. A coolant service evaluates the system fitted to the vehicle and checks for evidence of leakage or deterioration. Drivers may first notice a temperature gauge running higher than usual, a sweet smell, a puddle under the front of the vehicle, or coolant that looks rusty, cloudy or low in the reservoir. Those signs warrant an inspection instead of simply adding fluid.

Cooling system service at Mercedes-Benz of Draper

Mercedes-Benz of Draper provides coolant service for the 2025 Mercedes-Benz G-Class in Draper, Utah. The visit focuses on the condition of the coolant and the integrity of the cooling system: the fluid is drained and refilled with the manufacturer-specified type and concentration, the system is pressure-tested, and the hoses, cap, radiator and water pump area are inspected. That process gives the technician information needed to distinguish service that is due from a leak requiring repair.

Coolant service is also an opportunity to address early warning signs before they become a more disruptive cooling-system concern. The system should be checked cold because it is under pressure and hot after the vehicle has been running.
