818C1, 818C5 engines:
CAUTION: Whenever any crankshaft o. connecting rod
bearing is replaced, it is necessary after reassembly to
run the engine at idling speed until it reaches normal
opelating temperature, then continue to run it tor
approximalely 15 minutes.
Apply non-hardening liquid gasket to the block mat-
ing surface of the right side cover, and install it on
the cylinder block.
NOTEI
. Use liquid gasket, Part No. 08718 - 0001 or 08718- 0003,
. Check that the mating surfaces are clean and dry
before applying liquid gasket.
. Apply liquid gasket as an even bead, centered
between the edges of the mating surface.
. To prevent leakage of oil, apply liquid gasket to
the inner threads of the bolt holes.
. Do not install the parts if 5 minutes or more have
elapsed since applying the liquid gasket. Instead,
reapply liquid gasket after removing the old
residue.
After assembly, wait at least 30 minutes betore
filling the engine with oil.
RIGHT SIDE COVER:
Apply liquid gasket alongthe broken line.

Ambi€nt Temperature
An oil with a viscosity of 5 W 30 is preferred forimproved fuel economy and year-round protection inthe vehicle.
You may use a 10 W 30 oil if the climate in your area islimited to the temperature range shown on the chart.

Oil Pressure
Testing
lf the oil pressure warning light stays on with the enginerunning, check the engine oil level. It the oil level iscorrect:
Connect a tachometer.
Remove the oil pressure switch and install an oil pressure gauge.
Start the engine. Shut it off immediately if the gaugeregasters no oil pressure. Repair the problem beforecontinuing.
Allow the engine to reach operating temperature (fan
comes on at least twicel. The pressure should be:
Engine Oil Pressure:
At ldle: 70 kPa {O.7 kgficmr, tO psil
minimum
At 3,OOO rpm: 34O kPa (3.5 kgf/cmr, 50 psil
minimum
a lf oilpressure is within specifications, replace theengine oil pressure switch and recheck.
a lf oil pressure is NOT within specifications,rnspect the oil pump (see page g-11).

Oil Jet
lnspection(818C1, 818C5 engines
only)
1. Remove the oil jet (see pages 8 4 or 8 5) and inspectit as follows.
a Make sure rhat a 1 .1 mm (O.04 in) diameter drillwillgo through the nozzle hole fl.2 mm (O.O5 in)diameter).
a Insert the other end of the same 1 .1 mm {0.O4in) drill into the oit intake (1.2 mm (0.05 in)diameter).
Make sure the check ball moves smoothly and hasa stroke of approximately 4.0 mm (O.16 in).a Check the oil jet operation with an air nozzle. ltshould take at least 2OO kPa 12.O kg|lcm2, 2gpsi) to unseat the check ball.
NOTE: Replace the oiljet assembly if the nozzleis damaged or bent.
2. Mounting torque is critical. Be very precise when in-stalling.

This vehicle uses HFC-134a (R-134a) refrigerant which does not contain chlorofluorocarbons. Pay attention to the follow-ing service items:
. Do not mix refrigerants CFC-12 (R-12) and HFC-134a (R-134a). They are not compatible.. Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (ND-OIL 8: P/N 38897-PR7-A01AH or 38899-PR7-A01) designed for the R-134a compressor. Intermixing the recommended (PAG) refrigerant oil with any other refriger-ant oil will result in compressor failure.
. All AVC system parts (compressor, discharge line, suction line. evaporator, condenser, receiver/dryer, expansion valve.O-rings for joints) have to be proper for refrigerant R-134a. Do not confuse with R-12 parts.
. Use a halogen gas leak detector designed for refrigerant R-134a.. R-12 and R-134a refrigerant servicing equipment are not interchangeable. Use only a Recovery/Recycling/ChargingSystem that is U.L.-listed and is certified to meet the requirements of SAE J2210 to service R-134a air conditioning sys-tems.
. Always recover the refrigerant R-134a with an approved Recovery/Recycling/Charging System before disconnectingany Ay'C fitting.
