Coolant

Check the coolant level in the reservoir tank
when the engine is cold. (The coolant level will
vary with engine temperature.) The coolant
level is satisfactory if it is between the "FULL"
and "LOW" marks on the tank. If the coolant
level is at or below the "LOW" level, add tap
water (soft water) to bring the level up to
"FULL". Change the coolant every two years.
