2022 Mercedes-Benz CLS-Class Coolant: Specs & Service

The 2022 Mercedes-Benz CLS-Class uses a 3.0-liter inline-6 engine and requires premium unleaded fuel, making proper cooling-system condition important for dependable operation. Mercedes-Benz of Draper in Draper, UT, provides coolant service that drains and refills the system with the manufacturer-specified coolant type and concentration, pressure tests for leaks, and inspects key components. Coolant additives deplete over time even when the fluid still appears to cool normally, which can leave aluminum and gasket surfaces less protected. Booking this service helps distinguish coolant condition that calls for maintenance from a leak that needs repair. Schedule cooling system care at Mercedes-Benz of Draper for your 2022 Mercedes-Benz CLS-Class.

What a coolant service on a 2022 Mercedes-Benz CLS-Class involves

Coolant service begins with draining the existing coolant and refilling the system with the type and concentration the manufacturer specifies for the 2022 Mercedes-Benz CLS-Class. Using the specified fluid matters because coolant products are not interchangeable, and the correct mixture supports both temperature control and internal protection.

After the refill, the cooling system is pressure tested for leaks. Pressure testing helps separate a service that is due from a system that is losing coolant through a leak. The inspection also includes the hoses, cap, radiator and water-pump area, where signs of seepage, deterioration or other concerns may be found.

This service is especially relevant to the CLS-Class 3.0-liter inline-6, which relies on a properly maintained cooling system while producing 362 horsepower and 369 lb-ft of torque. If the temperature gauge runs higher than usual, the vehicle has a sweet smell or a puddle beneath the front, schedule service at Mercedes-Benz of Draper.

Why coolant condition matters on a 2022 Mercedes-Benz CLS-Class

Coolant does more than transfer heat away from the engine. Its additive package helps stop corrosion inside an aluminum cooling system and protects gasket surfaces exposed to the fluid. Those additives deplete on a timetable of their own, even while the coolant still looks like coolant and continues to move heat.

That is why appearance alone does not establish whether coolant is doing its protective job. Rusty, cloudy or low coolant can be a visible warning, but clear-looking fluid can still have depleted additives. Condition is judged through the manufacturer's maintenance schedule and by testing during a service visit.

The 2022 Mercedes-Benz CLS-Class pairs its 3.0-liter inline-6 with a 9-speed automatic transmission and 4MATIC all-wheel drive. A properly maintained cooling system supports consistent operation across normal driving conditions. If the temperature gauge is higher than usual or the reservoir level is low, coolant service can help identify whether maintenance or leak repair is needed.

Cooling system service at Mercedes-Benz of Draper

Mercedes-Benz of Draper provides cooling-system service for the 2022 Mercedes-Benz CLS-Class in Draper, Utah. The visit focuses on the coolant's condition and the system's ability to hold pressure, rather than treating a low level as the whole diagnosis. A sweet smell, a puddle under the front of the vehicle, or coolant that appears rusty or cloudy can make an inspection particularly important.

The service includes draining and refilling with the manufacturer-specified coolant type and concentration, pressure testing for leaks, and inspecting the hoses, cap, radiator and water-pump area. This process helps identify whether the vehicle needs routine coolant maintenance or whether a leak requires repair. Do not open a hot cooling system; it can remain under pressure after the engine runs, so checking is done cold.
