ENGINE MAINTENANCE (HR16DE)
1. Open radiator drain plug (1) at the bottom of radiator, and then remove radiator cap.
• Front
When draining all of engine coolant in the system, open
water drain plug on cylinder block. Refer to EM-96 .
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing. Refer to CO-16, " Component " .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system.
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. PBIC3799E

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 br ing 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 specif ied level and install the radiator cap. Run the engine to
warm up the cooling system and top up the system as necessary.
FLUSHING COOLING SYSTEM 1. Install reservoir tank if removed. Refer to CO-16, " Component " .
2. Install radiator drain plug. •If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-96, " Disassem-
bly and Assembly " .
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-16, " Component " .
3. Fill radiator and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the cooling system.
8. Repeat steps 1 through 7 until clear water begins to drain from radiator.
FUEL LINES
FUEL LINES : Checking Fuel Line INFOID:0000000004803414
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loos e connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.

3. Install oil pressure gauge and hose.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load. Refer to LU-10, " Engine Oil Pressure " .
If difference is extreme, check oil passage and oil pump for oil leaks.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification. Use Genuine Silicone RTV Sealant or equivalent. Refer to GI-42, " Recommended Chemical Product
and Sealant " .
c. Check engine oil level.
d. After warming up engine, make sure there are no leaks of engine oil with running engine.
ENGINE OIL : Draining INFOID:0000000004806011
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause ski n cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up the engine, park vehicle on a level surface and check for engine oil leakage from engine compo- nents. Refer to MA-20, " ENGINE OIL : Inspection " .
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove drain plug and then drain engine oil.
ENGINE OIL : Refilling INFOID:0000000004806012
1. Install drain plug with new washer. Refer to EM-39, " Exploded View " .
CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil. Engine oil specification and viscosity: Refer to MA-14, " Fluids and Lubricants " .
CAUTION:
• The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
• Always use oil level gauge to determine the pr oper amount of engine oil in the engine.
3. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop engine and wait for 10 minutes.
5. Check the engine oil level. Refer to MA-20, " ENGINE OIL : Inspection " .
