pump rotor shaft might be damaged.
Reassembly
1) Wash, clean and then dry all disassembled parts.
2) Apply thin coat of engine oil to inner and outer rotors,
and inside surfaces of oil pump case.
3) Reassemble oil pump. After reassembling oil pump,
check to be sure that rotor turns smoothly by hand.

• Check outer rotor, inner rotor and oil pump cases for
excessive wear or damage.
• Check relief valve for excessive wear or damage.
• Measure free length and tension of oil relief spring.
Spring (for oil pump) free length
63.47 mm (2.49 in.)
Spring (for oil pump) preload
80.38 – 88.22 N (8.04 – 8.82 kg, 58.14 – 63.80 lb) for
52.0 mm (2.05 in.)
• Radial clearance
Measure clearance of oil pump rotor and oil pump
case using thickness gauge.
Check radial clearance between outer rotor (2) and
case (1), using thickness gauge (3).
If clearance exceeds its limit, replace oil pump
assembly.
Radial clearance between oil pump outer rotor
and oil pump case
Limit: 0.19 mm (0.0075 in.)
• Side clearance
Using straightedge (5) and thickness gauge (4),
measure side clearance. If clearance exceeds its limit,
replace oil pump assembly.
Oil pump side clearance
Limit: 0.11 mm (0.0043 in.)

Engine
Engine Cooling System
General Description
Cooling System Description
S6JB0B1601001
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 Description
S6JB0B1601002
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 been 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.
