CHECKING COOLING SYSTEM HOSES
Check hoses for the following:
• Improper attachment
• Leaks
• Cracks
• Damage
• Loose connections
• Chafing
• Deterioration
CHECKING RESERVOIR LEVEL
• Check that the reservoir tank engine coolant level is within the
MAX (A) to MIN (B) range when the engine is cool.
• Adjust the engine coolant level if necessary.
CAUTION:
Refill the engine cooling system with the specified coolant or
equivalent. Refer to MA-11, "
Fluids and Lubricants".
CHECKING COOLING SYSTEM FOR LEAKS
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
CAUTION:
• Perform this step when the engine is cold.
• Do not spill engine coolant on drive belt.
To check for leaks, apply pressure to the cooling system using suit-
able tools (A) and (B).

4. Install the Tool by installing the radiator cap adapter onto the
radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the engine coolant mixture container that is placed at floor level. Make sure the ball valve is in the
closed position.
•Use recommended engine coolant or equivalent.
Refer to MA-11, "
Fluids and Lubricants".
CAUTION:
Do not use any cooling system additives such as radiator
sealer. Additives may clog th e cooling system and cause
damage to the engine, transmission and/or cooling system.
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Engine coolant wi ll be visible rising in the refill hose. Once the refill
hose is full of engine coolant, close the ball valve. This will purge any air trapped in the refill hose.
8. Continue to draw the vacuum until the gauge reaches 28 inches of vacuum. The gauge may not reach 28 inches in high altitude
locations, use the vacuum specifications based on the altitude
above sea level.
9. When the vacuum gauge has reached the specifi ed amount, disconnect the air hose and wait 20 seconds
to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the
system and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for any leaks.
10. Place the engine coolant container (with the refill hose inserted) at the same level as the top of the radia- tor. Then open the ball valve on the refill hose so the engine coolant will be drawn up to fill the cooling sys-
tem. The cooling system is full when the vacuum gauge reads zero.
CAUTION:
Do not allow the engine coolant co ntainer to get too low when filling, to avoid air from being drawn
into the cooling system.
11. Remove the Tool from the radiator neck opening.
12. Fill the cooling system reservoir tank to the specified level and install the radiator cap. Run the engine to warm up the cooling system and t op up the system as necessary.
13. Install the front under cover. Refer to EXT-39, "
