42 Engine
The cylinder block is a cast iron alloy, deep skirt
design and the crankshaft is supported in the cylinder
block by five precision insert replaceable main bear-
ings. Crankshaft end float is controlled by the flanged
centre main bearing. Connecting rods are I section
forgings equipped with precision insert replaceable big
end bearings. The gudgeon pins are an interference fit
in the connecting rod and a floating fit in the piston.

The cast aluminum pistons are equipped with
two compression rings and one oil control ring.

The twin rotor, involute gear oil pump is mounted
directly to the front face of the cylinder block. The
inner rotor is internally driven by the crankshaft. The
oil pump pressure relief valve is not adjustable, and
consists of a plunger and spring mounted in the oil
pump body.

The pump draws oil through a screen in the sump
and delivers it, via a full flow replaceable oil filter, to
the oil gallery from where it is distributed to the
hydraulic tappets, camshaft and crankshaft bearings
and to the overhead rocker and valve mechanism.

deteriorated.
ENGINE OVERHEATING
(1) Radiator cap defective: Renew the radiator
cap.
(2) Incorrect fuel mixture: Check the fuel system
as described in the Fuel and Engine Management
section. (3) Obstructed air passage through the radiator
core from the front to the rear: Blow the obstruction

When the engine is at normal operating
temperature and the heater valve is open,
both of the heater hoses should feel
warm/hot. If the valve is not allowing the
coolant to flow, one hose will be hot while
the other will be cold.

NO COOLED AIR INSIDE VEHICLE
(1) Compressor drive belt slipping or broken:
Renew and/or adjust the drive belt as described in the
Engine Tune-up section.
(2) Insufficient refrigerant: Check the system for
leaks and charge as necessary. Refer to the Air
Conditioning heading in th is section for information
on checking the refrigerant level. (3) Compressor inoperative: Check for power to
the compressor clutch before removing the compres-
sor for repair by a specialist. (4) Heater system allowing warm air to mix with
cooled air: Check the operation of the heater system.
NOTE: The above trouble shooting proce-
dures are basic checks only. If the air
conditioning system is suspect, it is rec-
ommended that the vehicle be taken to an
authorized dealer for testing and repair.
It is normal for water to be seen drain-
ing under the vehicle from the evaporator
after the vehicle has been operated with
the air conditioning on.

3. DESCRIPTION
The cooling system is of the sealed, pressurized
type with fan and water pump assistance. The system
is pressurized in order to raise the boiling point of the
coolant and so increase the efficiency of the engine.

Provision for pressure a nd vacuum relief of the
system is incorporated in the radiator cap.

The radiator overflow hose is connected to a
reserve tank mounted adjacent to the battery. As the
coolant volume expands due to an increase in tem-
perature, the pressure valve in the radiator cap opens
and allows the excess coolant to flow into the reserve
tank. When the engine is stopped and the temperature
of the coolant falls, the vacuum valve in the radiator
cap opens and allows the excess coolant in the reserve
tank to siphon back into the radiator. Thus the
necessity for frequent topping up of the coolant is
eliminated.

The temperature of the cooling system is con-
trolled by a thermostat located in the thermostat
housing attached to the cylinder head.

The thermostat prevents circulation of coolant
through the radiator by directing coolant through the
by-pass circuit, until the engine has reached operating
temperature. This restricted circulation allows the
engine to reach operating temperature quickly, im-
proving drivability and fuel economy.

Removal of the thermostat to cure overheating is
not recommended because th e by-pass circuit will
remain open reducing the amount of water flowing
through the radiator.

An anti-corrosion inhibitor should always be
added to the coolant to protect the cooling and
heating systems from corrosion.

The water pump is mounted to the front of the
engine and is driven by the camshaft drive belt. It is
equipped with a double row ball bearing and a spring
loaded seal assembly. The water pump is a disposable
unit and cannot be repaired.

The fan is driven by an electric motor which is
actuated by the coolant temperature sensor and the
control unit.

On vehicles equipped with air conditioning, an
additional electric fan is m ounted to the radiator. This
fan is controlled by a sw itch connected to the air
conditioning compressor.

The radiator consists of an aluminum core with
plastic side tanks. Minor damage to the core can be
repaired using Nissan repair agent.

The left hand tank of the radiator houses the
transaxle oil cooler on automatic transaxle models.

To drain the cooling system a drain plug is
provided on the lower radiator pipe outlet.

4. RADIATOR
NOTE: To avoid scalding, use caution when
releasing the radiator cap on an engine
which is at the normal operating tempera-
ture. Turn the cap anti-clockwise to the first
stop and allow any pressure in the system to
release. When the pressure is released turn
the cap past the stop and remove it from the
radiator.

CAUTION: To prevent severe electrical shock, extreme care must be taken when
working on or near the electronic ignition system as dangerous high tension voltages
are produced in both the primary and secondary circuits. See the text fo\

operations, refer to the Service Precautions
and Procedures heading.

ENGINE WILL NOT START OR HARD TO
START
(1) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter.
(2) Fault in the power supply: Check the battery,
fusible links and fuses. Check for clean, secure con-
nections, particularly the earth connections. Check the
EG1 and fuel pump relays.
NOTE: If the fuel pump relay fails, power
will be supplied to the fuel pump via the oil
pressure switch. When starting the engine,


Check that the MAP sensor hose is not blocked or split
and ensure that all electrical connections are clean and
secure.
