Adding Engine Coolant
1. Remove the pressure cap and pour
coolant mix slowly into the heat
exchanger to prevent the formation of
air pockets. Fill until the heat exchanger
is completely full. NOTICE: Only use the
engine coolant specified. Other engine
coolants may affect warranty coverage,
cause an internal buildup of rust and
scale and / or shorten engine life.
Prevent dirt and debris from
contaminating engine coolant. Carefully
clean the filler cap and the surrounding
area before you remove the cap.
NEVER mix different types of engine
coolants. This may adversely affect the
properties of the engine coolant.
2. Start the engine and allow to idle for
approximately 5 minutes.
3. Stop the engine and check the coolant
level. Add additional coolant if
necessary.
4. Install the pressure cap and tighten
firmly. WARNING! Securely tighten
the filler cap after checking the
coolant level. Steam can escape
during engine operation if the cap is
loose.
5. Remove the coolant recovery tank cap
and fill with coolant mix to approximately
50 mm (2 in.) below the full line. Replace
cap. Never fill to the full line.
6. After filling an empty cooling system,
test-run the engine for about five
minutes and check the engine coolant
level at the recovery tank again.
