NOTE:
Alcohol or methanol base coolant or plain water alone should not be used in cooling system at any
time as damage to cooling system could occur.
Even in a market where no freezing temperature is anticipated, mixture of 70% water and 30% ethyl-
ene glycol antifreeze (Antifreeze/Anticorrosion coolant) should be used for the purpose of corro-
sion protection and lubrication.
“Hard water”, if used, will foul up the cooling circuit by scale formation. Tap water available from
city water supply is the best available water, in a practical sense, for the cooling system. Distilled
water is ideal but is a luxury in most cases.
