INFOID:0000000011279699
LEVEL
• Check that the reservoir tank engine coolant level is within the
“MIN” to “MAX” when the engine is cool.
• Adjust the engine coolant level if necessary.
CAUTION:
Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent in its quality mixed with water (distilled or deminer-
alized). Refer to
MA-11, "Fluids and Lubricants"
CHECKING COOLING SYSTEM FOR LEAKS
• To check for leaks, apply pressure to the cooling system using suit-
able tools (A/B).
WARNING:
Do not remove the radiator cap when the engine is hot. Seri-
ous burns could occur from high-pressure engine coolant
escaping from the radiator. Wrap a thick 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 drivebelt.
• Higher test pressure than specified may cause radiator damage.
NOTE:
• If engine coolant decreases, replenish radiator with engine coolant. Refer to
• If anything is found, repair or replace damaged parts.

WARNING:
Do not remove radiator cap when engine is hot. Serious burns could occur from high pressure engine
coolant escaping the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quar-
ter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning
it all the way.
1. Open radiator drain plug at the bottom of radiator, and then
remove radiator cap.
CAUTION:
• Do not allow engine coolant to contact the drive belt.
• Perform this step when the engine is cold.

2. Follow this step for heater core removal/replacement only. Disconnect the upper heater hose at the
engine side and apply moderate air pressure [103.46 kPa (1.055 kg/cm
2
, 15 psi) maximum air pressure]
into the hose for 30 seconds to blow the excess engine coolant out of the heater core.
3. When draining all of the engine coolant in the system, remove the reservoir tank and drain the engine
coolant, then clean the reservoir tank before installation.
CAUTION:
• Do not allow the engine coolant to contact the drive belt.
• Perform this step when engine is cold.
4. When draining all of the engine coolant in the system for engine
removal or repair, remove the engine coolant drain plugs (A/B)
from the cylinder block.
5. Check the drained engine coolant for contaminants such as rust, corrosion or discoloration.
If the engine coolant is contaminated, flush the engine cooling system. Refer to
.
Refilling
INFOID:0000000011279701
CAUTION:
• Do not put additive such as waterleak preventive, since it may cause cooling waterway clogging.
• When refilling use Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality
mixed with water (distilled or demineralized). Refer to
MA-11, "Fluids and Lubricants"
1. Install the radiator drain plug. Install the reservoir tank and cylin-
der block drain plug, if removed for a total system drain or for
engine removal or repair.
• The radiator must be completely empty of coolant and
water.
• Apply sealant to the threads of the cylinder block drain
plug.
• Use recommended coolant or equivalent.

.
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heater ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.

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 coolant mixture container that is
placed at floor level. Make sure the ball valve is in the closed
position.
• Use recommended 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 the 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. Coolant will be visible rising in the refill hose. Once the refill hose is
full of 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 specified 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 coolant container (with the refill hose inserted) at the same level as the top of the radiator. Then
open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling
system is full when the vacuum gauge reads zero.
CAUTION:
Do not allow the coolant container 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 top up the system as necessary.
