Engine mechanism - Camshaft(4) Ensure whether the timing sprocket of VVT driver
will turn toward timing advance direction in de-
creasing the pressure of timing delay oil duct.
(5) When camshaft timing sprocket turns at max.
timing advance position, release the air pressure
in timing delay side oil duct, and then release the
air in timing advance side oil duct.
Hint: camshaft timing sprocket will turn only af-
ter the lock pin is released.
(d) Check the fixing state of max. delay position.
Ensure camshaft timing sprocket assembly is fixed at
max. delay position.11. Remove VVT driver assembly.(a) Clip the camshaft with a jaw vice, and ensure VVT driver
is locked tightly.
Warning: be careful not to damage camshaft.
(b) As shown in the diagram, seal 5 oil ducts of camshaft
journal with vinyl rubber cloth.
Hint: there are 2 advance side oil ducts in the
groove of camshaft, and clog one of them
with rubber block.
(c) In opposite side of the groove, respectively prick a hole
on vinyl rubber cloth of advance side oil duct surface
and delay side oil duct surface.
(d) Send in 2 oil ducts (advance side oil duct and delay
side oil duct) with the surface rubber cloth pricked
under the pressure of 150Kpa.
Warning:cover the oil ducts with cloth to avoid
oil injecting out in pushing.
(e) Ensure whether the timing sprocket of VVT driver will
turn toward timing advance direction in decreasing the
pressure of timing delay oil duct.
Hint: camshaft timing sprocket will turn toward
advance direction only after the lock pin is
released.
(f) When camshaft timing sprocket turns at max. timing
advance position, release the air pressure in timing
delay side oil duct, and then release the air in timing
advance side oil duct. Warning: if the air pressure in timing advance side oil duct is released earlier than that
in timing delay side oil duct, VVT driver assembly will move suddenly toward
delay side, and the lock pin will be damaged.
(c) Check rotating is smooth.
Besides max. delay position, turn VVT driver assembly within rotating rang and check rotating is
smooth.
Warning: Perform inspection with hands but not with
compressed air.55Delay side

Engine mechanism - CamshaftWarning: if the air pressure in timing advance side oil duct is released earlier than that in
timing delay side oil duct, VVT driver assembly will move suddenly toward
delay side.This will cause the damage of lock pin.
(g) Remove VVT drive fixed bolts.
Notes:
It is strictly forbidden to remove other 4 bolts.
Under the condition of repeating using camshaft
timing sprocket, release lock pin at first, and then
install sprocket.12. Install VVT driver assembly.
13. Install camshaft.Put VVT driver assembly together with intake camshaft.
(a) As shown in the diagram, gently make VVT assembly
hold camshaft and turn it toward left until straight pin is
inserted into groove.
Warning: it is strictly forbidden to turn camshaft
timing sprocket toward timing delay side
(toward right).
(b) Check there is no clearance between sprocket flange
and camshaft.
(c) Fix camshaft timing sprocket and then tighten flange
bolt.
Torque: 70 ±5N.m
(d) Check VVT driver assembly could move to timing
delay side and is locked at max. timing delay position.
(f) As shown in the diagram, align alignment mark with
timing mark on camshaft timing sprocket, and install
timing chain on the timing sprocket.
(g) Check forward mark and figure, and tighten bolts as
sequences shown in the diagram.
Torque: 13 ±0.78N.m

Cooling - Cooling syste2. Check engine coolant level in reservoir.Engine coolant level should be between “Low” and “Full” mark line.
Hint: if the level is too low, check there is leakage and refill coolant to “Full” mark line.3. Check engine coolant quality.(a) Remove radiator cap.
Warning: when the temperature of engine and radiator is high, do not remove radiator cap to
avoid being scalded, because coolant and steam will spurt under high pressure.
(b) Check there is too much rust deposit around radiator cap or at outlet and check there is flake; there
should not be oil in the coolant.
Hint: if coolant is too dirty, it is required to replace coolant.
(c) Install back radiator cap.Inspection1. Temperature regulatorHint: the figure on temperature regulator is the
opening temperature of valve.CoolingCooling systemOn-vehicle inspection1. Check there is leakage with cooling system.Warning: when the temperature of engine and radiator is
high, do not remove radiator cap to avoid be-
ing scalded, because coolant and steam will
spurt under high pressure.
(a) Refill coolant to radiator, and install radiator cap tester.
(b) Preheat engine.
(c) Pump tester to make pressure go up to 118KPa, and check
the pressure falls.
Hint: if the pressure falls, check there is leakage with
hose, radiator or water pump, and check heater,
cylinder body and cylinder head if no external leak-
age is found.66
LubricationLubricating systemOn-vehicle inspection1. Check oil level.During engine warming up and after it flames out for 5 minutes, check oil level, and the level should
be between two marks on oil dipstick at the moment.If oil level is too low, check there is leakage, and
refill oil up to upper mark on oil dipstick.
Note: oil level should not be above upper mark on oil
dipstick.2. Check oil quality.(a) Check there is deterioration, water penetration, color
change or thinning with oil.
(b) If oil quality becomes poor, please replace with new oil.
Hint: oil grades: API, SH, SJ, SG grade oil or ILSAC
multigrade oil. Recommended viscosity is
shown as below.

Note
1. Notes that are necessary for steering system:
(a) It is necessary to change parts correctly, for they will influence the performance of steering system to
make running danger.
2. Notes that are necessary for SRS airbag:
(a) MR7180 assembles with SRS (auxiliary protection system) such as safety airbag at the side of driver
and safety airbag at the side of passenger.
Maintenance does not accord with correct repair step, this might incur SRS explodes suddenly in
repair term to make heavy accident. Before repairing auxiliary protection system (including
disassembling, assembling, check or change parts), it is necessary to read the notes in SRS chapter
(auxiliary protection system).
