1999 NISSAN PRIMERA checking oil

CVT Fluid CheckNCAT0025FLUID LEAKAGE CHECKNCAT0025S011. Clean area suspected of leaking. Ð for example, mating sur-
face of converter housing and transmission case.
2. Start engine, apply foot brake, place selector lever in ªDº posi-
tion and wait a few minutes.
3. Stop engine.
4. Check for fluid leakage.
FLUID CONDITION CHECKNCAT0025S02
Fluid color Suspected problem

Overheating
FLUID LEVEL CHECKNCAT0025S03Refer to MA section (ªChecking CVT Fluidº, ªCHASSIS AND BODY
MAINTENANCEº).
Stall TestNCAT0026STALL TEST PROCEDURENCAT0026S011. Check CVT fluid and engine oil levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes or until engine oil and CVT
fluid reach operating temperature.

Checking Brake Fluid Level
lCheck fluid level in reservoir tank. It should be between Max.
and Min. lines on reservoir tank.
lIf fluid level is extremely low, check brake system for leaks.
lIf brake warning lamp comes on and fluid level is above
ªMINº mark, check brake fluid level switch and parking brake
switch.
Checking Brake Line
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake Fluid
CAUTION:
lRefill with new brake fluid ªDOT 4º.
lAlways keep fluid level higher than minimum line on
reservoir tank.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
1. Clean inside of reservoir tank, and refill with new brake fluid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake fluid from each air bleeder valve by depressing
brake pedal while keeping reservoir level higher than mini-
mum line by adding new brake fluid.
4. Repeat until new brake fluid comes out of each air bleeder
valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to ªBleeding Brake Systemº, BR-8.
Brake Burnishing Procedure
Burnish the brake contact surfaces according to the following
procedure after refinishing or replacing rotors, after replacing
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31
MPH).

SYSTEM OPERATION CHECK
Set voltmeter between glow plug and engine body.
1. Pre-glow control system
a. Turn ignition switch to ªONº position.
b. Read voltage.
Voltage:
Battery voltage for an engine coolant temperature
dependent time.
* Repeatedly turning the ignition switch to ªONº
position and to ªLOCKº position may change
the pre-glow time.
2. After-glow system
Start engine and read voltage.
Voltage:
Battery voltage for 5* minutes
* Engine coolant temperature is lower than 50ÉC
(122ÉF).
COMPONENT INSPECTION
Glow relay
1. Check relay for coil continuity between glow relay terminals
p1andp2.
Continuity should exist.
2. Check relay for proper operation by applying 12V dc voltage
between glow relay terminals
p1andp2and checking con-
tinuity between terminals

IOn models equipped with air conditioner, checks should
be carried out while the air conditioner is ªOFFº.
IWhen checking idle speed on models equipped with CVT,
ignition timing and mixture ratio, checks should be carried
out while shift lever is in ªPº or ªNº position.
IWhen measuring ªCOº percentage, insert probe more
than 40 cm (15.7 in) into tail pipe.
ITurn off headlamps, heater blower, rear window defogger.
IOn vehicles equipped with daytime running light systems,
set lighting switch to the 1st position to light only small
lamps.
IKeep front wheels pointed straight ahead.
IIf engine stops immediately after starting or idle condition
is unstable, perform the following to initialize IACV-AAC
valve:
a)Stop engine and wait 9 seconds.
b)Turn ignition ªONº and wait 1 second.
c)Turn ignition ªOFFº and wait 9 seconds.
IMake the check after the cooling fan has stopped.
