Based on industry averages you can expect to pay between $0.99 and $99.99 for a Mercedes 300SL coolant.

Mercedes 300SL coolant is a mixture of ethylene glycol and water that circulates through the engine to regulate its temperature. It is important because it helps absorb the heat generated by the engine, preventing overheating and damage to engine components. Without proper coolant levels, the engine could overheat and cause significant damage, leading to costly repairs or even engine failure. Regular maintenance of the coolant system, including checking levels and changing the coolant as needed, is crucial for maintaining the health of the engine.

Type of Coolant for Mercedes 300SL

The Mercedes 300SL coolant uses a mixture of ethylene glycol and water as its coolant. The recommended ratio is 50:50. It is important to use a coolant that meets the Mercedes-Benz specifications for the particular model year.

Mercedes 300SL Coolant Capacity by Year

  • 1954-1963: 12.5 quarts for the 3.0L inline-six engine
  • 1986-1989: 10.7 quarts for the 3.0L inline-six engine
  • 1990-1993: 13.7 quarts for the 3.0L inline-six engine

Note: These figures are only guidelines and may vary depending on several factors such as the type of cooling system, variations in engine type, and other factors. It's always best to consult the car manual or a trusted mechanic for accurate information regarding the coolant capacity for your specific Mercedes 300SL.

How to Add Coolant to Your Mercedes 300SL

  1. Start by parking the car and turning off the engine. Wait for some time until the engine cools down.
  2. Open the hood of the car and locate the coolant reservoir tank. It is usually transparent and labeled with "coolant" or a coolant symbol.
  3. Check the level of the coolant by looking at the markings on the side of the tank. If the level is below the minimum mark, you need to add more coolant.
  4. Prepare the coolant mixture as per the manufacturer's instructions. Make sure to use the recommended type of coolant. Most modern cars require a mixture of water and coolant in a specific ratio.
  5. Slowly pour the coolant into the reservoir tank until it reaches the maximum level mark. Be careful not to overfill the tank.
  6. Once you have added the coolant, close the cap tightly and start the engine. Let the engine run for a few minutes, then check the level of the coolant again. Add more coolant if required.
  7. Finally, make sure to dispose of the unused coolant safely according to local regulations.

Note: If you are unsure about adding the coolant yourself, it is recommended to take your car to a professional mechanic for assistance.
