Mercedes 250SE coolant typically cost between $3.29 and $35.59.

Coolant is a liquid that circulates through the engine of a car and helps regulate the temperature by absorbing the heat generated. It also prevents the engine from freezing during cold weather conditions. Coolant typically contains a mixture of water and ethylene glycol or propylene glycol, along with other additives that help prevent corrosion, foaming, and scaling.

Using the correct type of coolant is important because it can affect the performance and longevity of the engine. Different types of engines may require different types of coolant based on their materials (such as aluminum vs. cast iron), and using the wrong type of coolant can lead to corrosion, leaks, and other problems. Additionally, using too little or too much coolant can also cause issues with the engine's cooling system. Therefore, it is important to always refer to the manufacturer's recommendations for the type and amount of Mercedes 250SE coolant to use in your specific vehicle.

Type of Coolant for Mercedes 250SE

The Mercedes 250SE coolant uses a coolant that meets the Mercedes-Benz Specification 325.0 or equivalent. Most Mercedes-Benz dealerships use a coolant made by Pentosin that meets this specification.

Mercedes 250SE Coolant Capacity by Year

The coolant capacity of a car's engine is dependent on its year range and engine size. Here is a general guide for the Mercedes 250SE:

  • 1965 - 1967: 2.5 liters (engine size: 2496 cc)
  • 1967 - 1970: 4.5 liters (engine size: 2778 cc)

It's always best to consult your owner's manual or a qualified mechanic for accurate information regarding your specific vehicle.

How to Add Coolant to Your Mercedes 250SE

To add coolant to a Mercedes 250SE, you will need to follow these steps:

  1. Park the car on a level surface and turn off the engine.
  2. Open the hood and locate the coolant reservoir tank. It is usually located near the radiator and has a cap marked "coolant" or "engine coolant."
  3. Check the level of the coolant in the reservoir. If the level is low, the coolant should be added.
  4. Twist the cap counterclockwise to unscrew it and remove it from the reservoir.
  5. Using a funnel, slowly pour the coolant into the reservoir until the level reaches the "max" mark.
  6. Replace the cap and twist it clockwise until it is tight.
  7. Start the car and let it idle for a few minutes. This will allow the coolant to circulate through the system.
  8. Check the coolant level again after a few days of driving. If the level is low, add more coolant.

Note: Always use the coolant recommended for your Mercedes 250SE by the manufacturer. Do not mix different types of coolant as this can damage the engine. Also, make sure the engine is completely cooled down before adding coolant to avoid burns.
