2018 Mercedes-Benz G-Class Coolant

Mercedes-Benz G-Class Coolant service at Mercedes-Benz of Draper in Draper, UT

Frequently asked questions

The 2018 Mercedes-Benz G-Class uses a high-output V8 or V12 engine and four-wheel drive, making a healthy cooling system important for dependable operation. Mercedes-Benz of Draper in Draper, UT, provides coolant service that drains and refills the system with the coolant type and concentration the manufacturer specifies, then pressure-tests the system and inspects key components. Coolant additives deplete over time even while the fluid continues to carry heat, so service helps distinguish routine maintenance from a leak that needs repair. If the temperature gauge is running higher than usual, you notice a sweet smell or puddle, or the reservoir appears low or cloudy, book cooling system service for your 2018 Mercedes-Benz G-Class.

What a coolant service on a 2018 Mercedes-Benz G-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. Using the specified fluid matters because coolant formulations are not interchangeable, and the correct mixture supports the protection intended for the system's aluminum and gasket surfaces.

After the refill, the system is pressure tested for leaks. This step helps identify whether a low level or loss of coolant points to a condition requiring repair rather than simply a scheduled fluid service. The inspection also covers the hoses, cap, radiator and the area around the water pump. Together, these checks look beyond the fluid itself and assess the components that contain and circulate it.

Schedule service when the vehicle reaches its maintenance point or when you notice cooling-system symptoms. You can schedule service at Mercedes-Benz of Draper for a condition check and pressure test.

Why coolant condition matters on a 2018 Mercedes-Benz G-Class

Coolant does more than transfer heat away from the engine. Its additive package helps limit corrosion inside an aluminum cooling system and protects the surfaces and gaskets the fluid contacts. Those additives deplete on their own timetable, even when the coolant still looks like coolant and continues to move through the system.

That is why coolant condition is judged by the manufacturer's maintenance schedule and by testing at a service visit, rather than by appearance alone. The 2018 Mercedes-Benz G-Class is available with V8 and V12 engines across its trims, with horsepower ranging from 416 to 621 hp. That range reflects a substantial working load for the cooling system, particularly when the vehicle is operating under demanding conditions.

A higher-than-usual temperature gauge, sweet smell, puddle under the front of the vehicle, or rusty, cloudy or low coolant can point to a concern. A pressure test helps separate depleted coolant protection from a leak that needs attention.

Cooling system service at Mercedes-Benz of Draper

Mercedes-Benz of Draper provides coolant service for the 2018 Mercedes-Benz G-Class in Draper, UT. The visit connects the fluid service with an inspection of the system: the coolant is drained and refilled to the manufacturer's specified type and concentration, the system is pressure tested, and the hoses, cap, radiator and water pump area are examined.

This approach matters because adding fluid alone does not evaluate the system's pressure integrity or the condition of its protective additives. If the level continues to fall, the pressure test can help identify a leak rather than treating the symptom as normal consumption. A service visit also gives you a way to check coolant condition between scheduled maintenance points.

Frequently Asked Questions

6 common questions answered

What are the signs a 2018 Mercedes-Benz G-Class needs a coolant service?Higher-than-usual engine temperature, a sweet smell, a puddle, or rusty, cloudy or low coolant can signal that a 2018 Mercedes-Benz G-Class needs cooling-system attention.

The system should be checked cold because it is under pressure and hot after running. These signs can reflect depleted coolant protection or a leak, so a pressure test helps determine the next step.

  • Temperature gauge running higher than usual
  • Sweet smell or a puddle beneath the front of the vehicle
  • Rusty, cloudy or low coolant in the reservoir
What is included in a coolant service on a 2018 Mercedes-Benz G-Class?A coolant service on a 2018 Mercedes-Benz G-Class drains and refills the coolant, pressure tests the system, and inspects its key components.

The replacement coolant uses the type and concentration the manufacturer specifies for this vehicle. The inspection looks at the hoses, cap, radiator and water pump area, helping separate routine maintenance from a leak that needs repair.

  • Drain and refill with manufacturer-specified coolant
  • Cooling-system pressure test for leaks
  • Inspection of hoses, cap, radiator and water pump area
How often should the coolant in a 2018 Mercedes-Benz G-Class be changed?The manufacturer publishes a maintenance schedule for the 2018 Mercedes-Benz G-Class, and that schedule settles when the coolant should be changed.

Coolant condition can also be tested during a service visit between scheduled points. This matters because additives deplete over time even when the fluid still appears to cool the engine.

  • Follow the manufacturer's published maintenance schedule
  • Have coolant condition tested at a service visit
  • Book an inspection when cooling-system symptoms appear
What kind of coolant does a 2018 Mercedes-Benz G-Class use?The manufacturer specifies the coolant type for the 2018 Mercedes-Benz G-Class, and that specification should guide the refill.

Coolants are not interchangeable, so the correct product and concentration matter for system protection. Colour is not a reliable guide to what is in the bottle. Mercedes-Benz of Draper can refill the system according to the vehicle's manufacturer-specified requirements.

  • Use the manufacturer-specified coolant type
  • Do not select coolant by colour alone
  • Have the refill handled as part of the service
Can I just top off the coolant in a 2018 Mercedes-Benz G-Class?Topping off a 2018 Mercedes-Benz G-Class restores the coolant level but does not restore the depleted additive package or identify a leak.

A level that keeps dropping points to a leak rather than normal consumption. Never open the cooling system while it is hot or under pressure; checking it is done cold. Book an inspection so the condition and pressure integrity can be evaluated.

  • Adding coolant restores level only
  • A repeatedly low level calls for leak inspection
  • Check the system only when it is cold
How do I book cooling system service at Mercedes-Benz of Draper?You can schedule an appointment with Mercedes-Benz of Draper online or call 385-425-5461.

Booking gets the coolant's condition and the system's pressure tested, helping distinguish service that is due from a leak needing repair. The dealership is at 11548 Lone Peak Parkway in Draper, UT.
