The average cost of a Mercedes S420 coolant is between $0.99 and $82.99.

Coolant is a liquid that circulates through the engine to help regulate its temperature. It is important because if the engine overheats, it can cause significant damage, and even lead to engine failure.

Mercedes S420 coolant, also known as engine coolant or antifreeze, is designed specifically for this model and meets the manufacturer's specifications. Using the correct coolant is important because different types of engines require different formulations, and using an incompatible coolant can cause damage to the engine.

Regular maintenance of the coolant system, including checking the coolant level and replacing the coolant at regular intervals, is essential for the proper functioning of the engine and to prevent overheating.

Type of Coolant for Mercedes S420

The Mercedes S420 uses a coolant that meets the specification MB 325.0, which is a long-life coolant suitable for use in aluminum engines. The recommended brand of coolant for Mercedes-Benz vehicles is Pentosin. It is important to follow the manufacturer's recommendations for coolant type and replacement intervals to ensure proper engine performance and longevity.

Mercedes S420 Coolant Capacity by Year

  • 1994-1999 Mercedes S420 (4.2L V8 engine): 13.0 quarts (12.3 liters)
  • 2000-2006 Mercedes S430/S500 (4.3/5.0L V8 engine): 14.0 quarts (13.2 liters)
  • 2007-2013 Mercedes S550 (5.5L V8 engine): 16.0 quarts (15.1 liters)
  • 2014-2020 Mercedes S550 (4.6L V8 engine): 14.8 quarts (14.0 liters)

Please note that these are general figures and may vary depending on the specific model year, engine type, and other factors. It's always best to consult the owner's manual or a certified Mercedes mechanic for exact capacity specifications.

How to Add Coolant to Your Mercedes S420

  1. Make sure the engine is cool before attempting to add coolant.
  2. Locate the coolant reservoir. It is usually located on the passenger side of the engine compartment, towards the front of the car.
  3. Remove the cap from the reservoir by turning it counterclockwise. Some models may have a latch that needs to be lifted first.
  4. Check the level of the coolant in the reservoir. If the coolant level is low, add the appropriate coolant to the reservoir. You can check the owner's manual or use a coolant brand that is recommended for Mercedes S420.
  5. Pour the coolant slowly into the reservoir until it reaches the “full” line. Be careful not to overfill the reservoir.
  6. Once the coolant is added, replace the cap by turning it clockwise until it clicks into place.
  7. Check the coolant level regularly and add more coolant if necessary.

Note: It is important to use the correct type of coolant for your Mercedes S420, as using the wrong type can cause damage to the engine. Check your owner’s manual or consult a mechanic if you are unsure what type of coolant to use.
