Here's what to keep in mind:
* Mercedes-Benz recommends using their own brand of coolant, which is typically a pre-mixed 50/50 solution of ethylene glycol and water. You can find this at Mercedes dealerships or authorized service centers.
* Check your owner's manual for the specific coolant recommendation.
* Avoid using "universal" or "all-makes" antifreeze. These may not be compatible with your car's cooling system and could cause damage.
* The recommended coolant concentration for your 1988 300E is likely 50% antifreeze and 50% water. This provides optimal protection against freezing and overheating.
* Ensure the coolant meets the proper specifications for your vehicle. This information should be listed in your owner's manual or on the coolant container.
It is crucial to use the correct type of engine coolant for your vehicle to prevent damage to your engine and cooling system.
