2025 Mercedes-Benz AMG GT Coolant in Lynnfield, MA

These symptoms can indicate depleted coolant protection or a leak in the cooling system. Because the system may be hot and pressurized after driving, checking should be done only when cold. A pressure test helps identify whether fluid loss is occurring.

• Temperature gauge running higher than usual
• Sweet coolant smell or a puddle beneath the vehicle
• Rusty, cloudy, or low coolant in the reservoir

The refill uses the type and concentration the manufacturer specifies for this vehicle. The pressure test looks for leaks, while the inspection covers hoses, the cap, the radiator, and the water pump area. These steps help distinguish routine service from a repair concern.

• Drain and refill with manufacturer-specified coolant
• Pressure test for leaks
• Inspect hoses, cap, radiator, and water pump area

That schedule should guide replacement decisions rather than fluid appearance alone. Coolant additives deplete while the fluid may still look normal, so condition can also be tested during a service visit between scheduled points. The inspection can identify whether the system needs routine service or leak diagnosis.

• Follow the manufacturer’s maintenance schedule
• Test coolant condition at a service visit
• Pressure-test the system when fluid loss is suspected

Coolants are not interchangeable, so the correct product and concentration should be selected for this vehicle. Colour is not a reliable guide to what is in the bottle and should not be used to choose a replacement. Mercedes-Benz service staff can verify the proper coolant requirement during the visit.

• Use the manufacturer-specified coolant type
• Do not treat different coolants as interchangeable
• Do not identify coolant by colour alone

If the level keeps dropping, the vehicle may have a leak rather than normal coolant consumption. The cooling system is under pressure and hot after running, so it should not be opened until cold. A coolant service and pressure test can determine whether the fluid needs service or the system needs repair.

• Adding coolant restores level only
• A recurring low level warrants leak inspection
• Never open the system while hot or pressurized
