Coolant: Service Precautions

CAUTION:
Failure to use proper antifreeze could cause radiator plugging and engine overheating. Do not mix antifreeze brands or use plain water or alcohol base antifreeze products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator coolant and may plug the radiator.
