Engine
Engine Lubrication System
General Description
Engine Lubrication DescriptionS7RS0B1501001
The oil pump is of a trochoid type, and mounted on the
crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into two paths in cylinder block.
The filtered oil is passed to the passage in heat
exchanger and cylinder block to piston cooling valve of
oil gushed to the lower side of piston. In one path, oil reaches the crankshaft journal bearings.
Oil from the crankshaft journal bearings is supplied to
the connecting rod bearings by means of intersecting
passages drilled in the cran
kshaft, and then injected
from the big end of connecting rod to lubricate piston,
rings and cylinder wall.
In the other path oil goes up to the cylinder head and
lubricates valves and camshafts, etc., after passing
through the internal oil way of camshafts.
An oil relief valve is provided on the oil pump. This valve
starts relieving oil pressure when the pressure exceeds
about 350 kPa (3.5 kg/cm
2, 49.8 psi).

• Oil quality If oil is discolored or deteriorated, change
it. For particular oil to be used, refer to
“Engine Oil and Filter Change in Section
0B”.
• Oil leaks If leak is found, repair it.

1) Remove front bumper referring to “Front Bumper and Rear Bumper Components in Section 9K”.

Engine Cooling System
General Description
Cooling System DescriptionS7RS0B1601001
The cooling system consists of the radiator cap, radiator, coolant reservoir, hoses, water pump, cooling fan and
thermostat. The radiator is of tube-and-fin type.
Coolant DescriptionS7RS0B1601002
WARNING!
• Do not remove radiator cap to check engine coolant level; check coolant visually at the see-through coolant reservoir. Coolant should be added only to reservoir as necessary.
• As long as there is pressure in the cooling system, the temperature can be considerably higher than the boiling temperature of the solution in the radiator without causing the solution to boil. Removal
of the radiator cap while engine is hot and pressure is high will cause the solution to boil
instantaneously and possibly with explosive force, spewing the solution over engine, fenders and
person removing cap. If the solution contains flammable anti-freeze such as alcohol (not
recommended for use at any time), there is also the possibility of causing a serious fire.
• Check to make sure that engine coolant temperature is cold before removing any part of cooling system.
• Also be sure to disconnect negative cable from battery terminal before removing any part.

The coolant recovery system is standard. The coolant in the radiator expands with heat, and the coolant is overflowed
to the reservoir.
When the system cools down, the coolant is drawn back into the radiator.
The cooling system has be en filled with a quality coolant that is a 50/50 mixture of water and ethylene glycol
antifreeze.
This 50/50 mixture coolant solution provides freezing protection to –36 °C (–33 °F).
• Maintain cooling system freeze protection at –36 °C (–33 °F) to ensure protection against corrosion and loss of
coolant from boiling. This should be done even if freezing temperatures are not expected.
• Add ethylene glycol base coolant when coolant has to be added because of coolant loss or to provide added protection against freezing at temperature lower than –36 °C (–33 °F).
NOTE
• Alcohol or methanol base coolant or plain water alone should not be used in cooling system at any
time as damage to cooling system could occur.
• Coolant must be mixed with deminerated water or distilled water.

• Inspect strut for oil leakage, damage or deformation.
• If defect is found, replace strut as an assembly unit, because it can not be disassembled.
• Inspect strut function re ferring to the following
procedures:
1) Check and adjust tire pressures as specified.
2) Bounce vehicle body up and down 3 or 4 times continuously by pushing front end of the vehicle side
body to check strut.
Also, note how many times vehicle body rebounds to
stop after force application.
3) Repeat the same procedure to the other strut to confirm that the both side struts equally respond.
If conditions of struts are in doubt, compare them with
known-good vehicle or strut.
• Inspect bearing for wear, abnormal noise or gripping. If defective, replace.
• Inspect coil spring seat for cracks or deformation.
If defective, replace.
• Inspect bump stopper for deterioration. If defective, replace.
• Inspect rebound stopper and strut mount for wear, cracks or deformation.
If defective, replace.
