Mercedes S55 coolant typically cost between $0.99 and $32.99.

Mercedes S55 coolant, also known as antifreeze, is a liquid that circulates through the engine of a vehicle to regulate its temperature. Its primary function is to prevent the engine from overheating by transferring heat from the engine to the radiator, where it dissipates into the air.

In addition to regulating the engine's temperature, coolant also helps prevent corrosion and rust in the engine and cooling system. It also plays a role in maintaining the proper pressure levels within the system.

Proper coolant maintenance is essential to ensure the longevity and optimal performance of a vehicle's engine. It is recommended to check and replace the coolant at regular intervals specified by the manufacturer. Using the correct type of coolant for your specific vehicle is also important as using the wrong type can cause damage to the engine and cooling system.

Type of Coolant for Mercedes S55

The Mercedes S55 coolant uses a combination of ethylene glycol-based coolant and distilled water, mixed at a ratio of 50:50. It is recommended to use coolant that meets Mercedes-Benz specifications or equivalent, such as Pentosin or Zerex G-05.

How to Add Coolant to Your Mercedes S55

  1. Park your car in a flat and level surface, and turn off the engine.
  2. Allow the engine to cool completely before attempting to open the coolant reservoir or radiator cap. This can take several hours.
  3. Locate the coolant reservoir, which is usually located near the engine bay. The coolant reservoir has a cap labeled "coolant" or "engine coolant only".
  4. Carefully remove the cap of the coolant reservoir. If your car has been running, be careful as the coolant may be hot and steam may escape.
  5. Check the coolant level in the reservoir. If it is low, you will need to add more coolant. Most cars require a 50/50 mix of coolant and water.
  6. Prepare the coolant mixture according to the manufacturer's instructions. Most coolants come premixed, but if you are using pure coolant, you will need to mix it with water before adding it to the reservoir.
  7. Slowly pour the coolant mixture into the coolant reservoir until the level reaches the "max" line. Be careful not to overfill it.
  8. Replace the cap of the coolant reservoir and make sure it is securely tightened.
  9. Start the engine and check for any leaks or low coolant warning lights.
  10. Take the car for a short drive to circulate the coolant and check the temperature gauge to ensure that the engine is not overheating.

It's recommended to check the coolant level regularly, especially during hot weather or when your car is subjected to heavy usage. Regular checks will help prevent engine damage and ensure your car runs smoothly.
