Antifreeze
The engine cooling system uses a mixture of 50% ethylene glycol antifreeze and 50% water.
Warning. If the antifreeze concentration is below 30%, it will significantly reduce the anti-corrosion ability. If the concentration is higher than 60%, the antifreeze protection and engine cooling ability will be reduced, which will adversely affect the engine. Make sure the concentration level is within the recommended range.
