head can be cracked due to difference in temperature between
engine block or cylinder head and coolant.
Add coolant to radiator only when engine is stopped or idling.
Clean cooling system every 2000 hours of operation or once
every year. in areas where water has a high mineral content,
clean cooling system more frequently.
