DIAGNOSTIC PROCEDURE
SYMPTOM: Magnet clutch does not engage when A/C switch
and fan switch are ON.
CHECK POWER SUPPLY FOR COM-
PRESSOR.
Disconnect compressor harness connector.
Do approx. 12 volts exist between compres-
sor harness terminal No.j

Maintenance of Lubricant Quantity in
Compressor
The lubricant used to lubricate the compressor circulates through
the system with the refrigerant. Add lubricant to compressor when
replacing any component or after a large gas leakage occurred. It
is important to maintain the speci®ed amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
+Lack of lubricant: May lead to a seized compressor
+Excessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANT
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the ¯owchart shown
below.
START
Can lubricant return operation be per-
formed?
+A/C system works properly.
+There is no evidence of a large amount of
lubricant leakage.
No
cYe s
Perform lubricant return operation, proceeding as follows:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Start engine, and set the following conditions:
+Test condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is
25 to 30ÉC (77 to 86ÉF).]
2. Perform lubricant return operation for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant
return operation.
Should the compressor be replaced?
No Yes
b
jA(Go to next page.)
Is there any part to be replaced?
(Evaporator, condenser, liquid tank or in
case there is evidence of a large amount of
lubricant leakage.)
No
cYe s
After replacing any of the following major components, add the correct
amount of lubricant to the system.
Amount of lubricant to be added
*1: If compressor is replaced, addition of lubricant is included in the ¯ow
chart.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Carry out the A/C performance test.b

section (``Changing Engine Coolant'', ``ENGINE MAINTE-
NANCE'').
4. Remove radiator shroud.
5. Remove drive belts. Refer to MA section (``Checking Drive
Belts'').
6. Remove crankshaft pulley and front upper and lower belt cov-
ers. Refer to EM section (``TIMING BELT'').
7. Remove oil pan. Refer to EM section (``OIL PAN'').
8. Remove oil strainer.
9. Remove oil pump assembly.
10. Installation is in reverse order of removal.
+Before installing oil pump, remove liquid gasket from mating
surface of oil pump using a scraper.

REGULATOR VALVE INSPECTION
1. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve
spring.
3. Coat regulator valve with engine oil and check to make sure
that it falls smoothly into the valve hole by its own weight.
If damaged, replace regulator valve set or oil pump assembly.
OIL PRESSURE RELIEF VALVE INSPECTION
Inspect oil pressure relief valve for movement, cracks and breaks
by pushing the ball. If replacement is necessary, remove valve by
prying it out with a screwdriver.
Install a new valve in place by tapping it.
