2016 Mercedes-Benz GL-Class Coolant: Specs & Service

The 2016 Mercedes-Benz GL-Class uses a liquid cooling system to manage heat through its engine and related components, making coolant condition important for dependable driving in every season. At Mercedes-Benz of Draper in Draper, UT, a coolant service helps assess whether the fluid and system still provide the protection the vehicle needs. The service includes draining and refilling with the coolant type and concentration the manufacturer specifies, pressure testing for leaks, and inspecting key components around the system. For a 2016 Mercedes-Benz GL-Class with a 3.0-to-5.5-liter engine and diesel or premium-unleaded fuel, booking service can distinguish coolant that is due for replacement from a leak requiring repair.

What a coolant service on a 2016 Mercedes-Benz GL-Class involves

A coolant service begins with draining the existing coolant and refilling the system with the type and concentration the manufacturer specifies for this vehicle. The system is then pressure tested to look for leaks that could allow coolant to escape when the vehicle is operating. Alongside that test, the service includes inspection of the hoses, the cap, the radiator, and the area around the water pump. These steps address both coolant condition and the system's ability to contain and circulate it.

That distinction matters because a fluid change alone cannot identify a leak, while a pressure test alone does not renew depleted coolant additives. The inspection helps connect a low reservoir, a sweet smell, or a puddle under the front of the vehicle with the condition of the cooling system. If your 2016 Mercedes-Benz GL-Class is due for coolant service or shows a cooling-system symptom, schedule service at Mercedes-Benz of Draper.

Why coolant condition matters on a 2016 Mercedes-Benz GL-Class

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

The 2016 Mercedes-Benz GL-Class is offered across its trims with engines ranging from 3.0 to 5.5 liters and diesel or premium-unleaded fuel requirements. Regardless of the engine configuration, the cooling system must maintain the proper operating temperature and remain sealed. A higher-than-usual temperature gauge, rusty or cloudy coolant, or a reservoir that looks low deserves attention. Coolant service can help identify whether the fluid needs renewal or whether a leak is affecting the system.

Cooling system service at Mercedes-Benz of Draper

At Mercedes-Benz of Draper, coolant service for the 2016 Mercedes-Benz GL-Class focuses on the condition of the fluid and the integrity of the cooling system. The visit includes the manufacturer-specified drain and refill, a pressure test for leaks, and inspection of the hoses, cap, radiator, and water pump area. Together, these checks help separate scheduled maintenance from a problem that needs repair, giving the technician a clearer picture than a visual fluid check alone.

Booking also makes sense when the temperature gauge runs higher than usual, when a sweet smell or puddle appears near the front of the vehicle, or when the reservoir looks low. The manufacturer's published maintenance schedule calls for coolant flush or replacement every 36,000 miles.
