2018 Mercedes-Benz CLS-Class Coolant: Specs & Service

The 2018 Mercedes-Benz CLS-Class is a V8-powered sedan with a cooling system that deserves scheduled attention, and Mercedes-Benz of Draper in Draper, UT, can help keep that system in proper condition. A coolant service drains and refills the system with the coolant type and concentration the manufacturer specifies, pressure tests for leaks, and inspects key components. This matters because coolant additives deplete over time even while the fluid still appears to cool normally. The manufacturer publishes a coolant replacement schedule for this model, while testing can help identify a leak or condition concern between scheduled services. If your temperature gauge is running higher than usual, you notice a sweet smell or puddle, or the reservoir looks low, cloudy or rusty, schedule service.

What a coolant service on a 2018 Mercedes-Benz CLS-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, rather than relying on a universal assumption about what belongs in the reservoir. The next step is a pressure test. Testing helps identify leaks that may not be obvious during a visual inspection and helps separate a service that is due from a repair concern.

Alongside the pressure test, the service includes inspection of the hoses, the cap, the radiator and the area around the water pump. These parts work together to move and contain coolant as the V8 engine operates. A low level, residue, damaged hose or pressure loss can point to a condition that needs attention beyond a routine drain and refill. For the right next step, schedule service at Mercedes-Benz of Draper.

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

Coolant does more than carry heat away from the engine. Its additive package helps protect the aluminum and gasket surfaces through which it flows, but those additives deplete on a timetable of their own. The fluid may still look like coolant and continue transferring heat while its corrosion protection has weakened. That is why coolant condition should be considered through the manufacturer’s schedule and service testing, not appearance alone.

The 2018 Mercedes-Benz CLS-Class uses a V8 engine, so maintaining the cooling system supports the temperature control that the engine requires during normal operation. A higher-than-usual temperature gauge, a sweet smell, a puddle beneath the front of the vehicle, or coolant that appears rusty, cloudy or low deserves attention. A pressure test can help distinguish a due service from a leak that needs repair. Schedule a visit before a small cooling-system concern becomes a larger one.
