ENGINE COOLANT
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. Install the reservoir tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be complete ly empty of coolant and water.
• Apply sealant to the threads of the cylinder bl ock drain plugs. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-42, " Recommended Chemical Product and Sealant " .
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er 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 Genuine NISSAN Long Life Anti-freeze coolant or
equivalent, mixed with distil led water or demineralized
water.
Refer to MA-15, " Anti-freeze Coolant Mixture Ratio " .
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 vi sible 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 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.

WATER OUTLET AND WATER CONTROL VALVE
• Place a thread (A) so that it is c aught in the valves of water control
valve (1). Immerse fully in a container (B) filled with water. Heat
while stirring.
• The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
• Continue heating. Check the full-open valve lift amount.
NOTE:
The full-open valve lift amount standard temperature for water con-
trol valve is the reference value.
• After checking the full-open valve lift amount, lower the water tem- perature and check the valve closing temperature.
• If out of the specification, replace water control valve.
INSTALLATION
Installation is in the reverse order of removal.
• Use the following procedure to install the water control valve.
- Install water control valve while making rubber ring (1) groove fit to water control valve flange (A) around the whole circumference.
CAUTION:
Replace the rubber ring with a new one.
- While the mark (A) points to up, install water control valve (2) with frame center (B) facing straight upward into water outlet (1).
• Use the following procedure to install the water outlet.
- Install the water outlet to the cylinder head without disp lacing the water control valve from the valve position.
• Use the following procedure to install the water hoses. Valve opening temperature 93.5 - 96.5
°C (200 - 206 °F)
Full-open valve lift amount 8 mm/ 108 °C (0.315 in/ 226 °F)
