The Maruti Suzuki 800 typically uses a coolant mixture that is a 50-50 combination of ethylene glycol and water. This mixture offers optimal protection against freezing and overheating for the car's cooling system. The coolant also includes corrosion inhibitors to help prevent damage to the metal components of the engine's cooling system.
It's essential to change the coolant regularly according to the owner's manual. Failing to do so can compromise the effectiveness of the cooling system.
