ENGINE MAINTENANCE (VQ35DE ENGINE)
 When engine coolant overflows air relief hole on heater hose,install air relief plug with new O-ring.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warming- up time is approximately 10 minutes at 3,000
rpm.
 Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop the engine and cool down to less than approximately 50 °C (122 °F).
 Cool down using fan to reduce the time.
 If necessary, refill radiator up to filler neck with engine coolant.
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to 3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
 Sound may be noticeable at heater unit.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 4 through 7 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-123, "
Dis-
assembly and Assembly".
2. Remove air relief plug on heater hose.
3. Fill radiator with water until water spills from the ai r relief hole, then close air relief plug. Fill radiator and

Checking Drive BeltsINFOID:0000000001328909
WARNING:
Be sure to perform when the engine is stopped.
 Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.
 Remove front engine undercover with power tool when inspecting power steering oil pump belt.
 Make sure that indicator (single line notch) of eac h auto tensioner is within the allowable working range
(between three line notches).
NOTE:
 Check auto tensioner indication when engine is cold.
 When new drive belt is installed, the range should be “A”.
 The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C com-
pressor belt, while it is found on the fi xed side for power steering oil pump belt.
 Visually check entire belt for wear, damage or cracks.
 If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentINFOID:0000000001328910
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantINFOID:0000000001328911
WARNING:
 To avoid being scalded, do not change engine coolant when engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressu re. Then turn radiator cap all the way.
 Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT

to EM-242, "
Disassembly and Assembly".
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system. Refer to "FLUSHING COOLING SYSTEM".
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-242, "
Dis-
assembly and Assembly".
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug on heater hose.
4. Fill thermostat housing and reservoir tank to specified level. Refill engine coolant up to fill er neck of thermostat housing.
 Pour engine coolant through engine coolant filler neck slowly of less than 2 (2-1/8 US qt, 1-3/4
Imp qt) a minute to allo w air in system to escape.
 Use Genuine NISSAN long Life Antifreeze/Coolant or equivalent mixed with water (distilled or
demineralized). Refer to MA-9
