The 2014 Mercedes-Benz SL-Class is a rear-wheel-drive convertible with V8 or V12 power, premium unleaded fuel, and a high-output engine that depends on stable operating temperature. A coolant service at Mercedes-Benz of Draper in Draper, UT helps assess whether the cooling system is protecting the engine as intended. The service includes draining and refilling the coolant with the manufacturer-specified type and concentration, pressure testing for leaks, and inspecting key components around the system. Coolant additives deplete over time even when the vehicle still appears to cool normally, so a condition check can distinguish maintenance needs from a leak requiring repair. Schedule service when the temperature gauge runs higher than usual, a sweet smell appears, or coolant looks rusty, cloudy, or low.
What a coolant service on a 2014 Mercedes-Benz SL-Class involves
Coolant service begins with draining the existing coolant and refilling the system with the type and concentration the manufacturer specifies for this vehicle. The goal is to restore the fluid's intended protective properties while maintaining the cooling performance required by the SL-Class's V8 and V12 engines. The system is then pressure tested to help identify leaks that may not be obvious during a visual check.
Alongside the pressure test, the inspection covers the hoses, the cap, the radiator, and the area around the water pump. These checks help separate coolant that has reached the end of its useful condition from a system that is losing coolant or needs repair. A low reservoir, residue, or a sweet smell can point to a condition that topping off alone will not correct. To have the cooling system assessed, schedule service with Mercedes-Benz of Draper.
Why coolant condition matters on a 2014 Mercedes-Benz SL-Class
Coolant does more than carry heat away from the engine. Its additive package helps limit corrosion inside the aluminum surfaces and gasket areas through which the fluid travels. 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 condition is judged through the appropriate service process and the manufacturer's maintenance guidance rather than appearance alone.
The 2014 Mercedes-Benz SL-Class uses powerful V8 and V12 engines, with output ranging from 429 to 621 horsepower across its trims. Keeping the cooling system in sound condition supports temperature control during normal driving and protects against the consequences of leaks or depleted corrosion protection. The maintenance schedule for this model year does not state a coolant interval here, so a service visit can help evaluate the fluid and system condition directly.

Frequently Asked Questions
6 common questions answered
What are the signs a 2014 Mercedes-Benz SL-Class needs a coolant service?Higher-than-usual gauge readings, a sweet smell, a puddle, or rusty, cloudy, or low coolant are signs to book a coolant inspection.
These symptoms can indicate depleted coolant protection or a leak, and they should not be judged by fluid level alone. The system is under pressure and hot after running, so checking it should be done cold. A pressure test helps determine whether the concern is maintenance or a repair need.
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 2014 Mercedes-Benz SL-Class?The service drains and refills the coolant, pressure tests the system, and inspects the hoses, cap, radiator, and water pump area.
The replacement coolant is the type and concentration the manufacturer specifies for this vehicle. Testing helps identify leaks that a refill would not resolve, while the component inspection adds context to the system's condition. This process is designed to distinguish a coolant service from a repair that requires further attention.
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 2014 Mercedes-Benz SL-Class be changed?The manufacturer's maintenance schedule settles when coolant service is due, and no interval is stated for this model year here.
Coolant condition can also be tested during a service visit between scheduled maintenance points. Additives deplete independently of how the fluid looks, so appearance is not a reliable replacement for testing and schedule-based maintenance. If the vehicle shows a temperature change, smell, puddle, or low reservoir, book an inspection rather than waiting for a routine point.
Follow the manufacturer's maintenance schedule
Have coolant condition tested at a service visit
Request inspection when cooling-system symptoms appear
What kind of coolant does a 2014 Mercedes-Benz SL-Class use?The manufacturer specifies the coolant type for this vehicle, and that specification should be followed during service.
Coolants are not interchangeable, and colour is not a reliable guide to what is in the bottle. Mercedes-Benz of Draper uses the vehicle's manufacturer requirement as the basis for the drain-and-refill service without relying on colour alone. If the system needs attention, the fluid and related components can be assessed together.
Use the manufacturer-specified coolant type
Do not choose coolant by colour alone
Do not assume different coolants are interchangeable
Can I just top off the coolant in a 2014 Mercedes-Benz SL-Class?Topping off restores the coolant level but does not restore the depleted additive package or identify why the level changed.
A level that keeps dropping indicates a leak rather than normal consumption and calls for an inspection. The cooling system is under pressure and hot after running, so checking it should be done cold. A pressure test can help determine whether the system needs service, repair, or both.
Adding coolant does not renew its protective additives
A repeatedly low level can indicate a leak
Have the system checked cold by a service professional
How do I book cooling system service for a 2014 Mercedes-Benz SL-Class at Mercedes-Benz of Draper?You can book online through the Mercedes-Benz of Draper service scheduler or call 385-425-5461.
Mercedes-Benz of Draper is at 11548 Lone Peak Parkway, Draper, UT 84020. Booking the visit gets the coolant's condition and the system's pressure tested, helping separate service that is due from a leak requiring repair. The service team can then explain the inspection findings and next step.
