CHANGING COOLANT
Coolant should be removed, and the system
flushed and filled with new coolant every 2000
hours or 2 years.
Procedure:
CAUTION: To avoid personal injury
from hot coolant, do not turn radiator
cap until engine cools. Turn the cap
to the first notch to relieve pressure
before removing cap completely. Use a ladder
as shown on previous page to access radiator.

gallons (30 litres) will be adequate.

solution of clean water and a heavy duty
radiator cleaner. Follow instructions provided
