(3) Check VSV operation from hole E to F and that the air flow should be difficult. See (Figure 114).
3. PCV sub-assembly
It should be easy for air to pass through the cylinder head.
Notice:
z
Do not suck air through valve.
z
Never put any object into the valve. Replace PCV if the operation is
not as specified.
z
Blow air in from the intake manifold side. Check that the air flow
should be difficult. Replace PCV if the operation is not as specified. See
(Figure 115).

1. Detach tail exhaust pipe assembly
Remove 2 bolts and the tail exhaust pipe assembly.
2. Remove intermediate exhaust pipe assembly
Replace exhaust system
Detach 2 bolts and intermediate exhaust pipe assembly.
3. Detach front exhaust pipe assembly
Remove 2 bolts and front exhaust pipe assembly.
4. Install front exhaust pipe assembly
Using vernier calipers, measure the free length of the spring.
Free length: 42mm
Using the new gasket, install the front exhaust pipe to the exhaust manifold.
Notice:
z
Do not use removed gasket any more.
5. Install front exhaust pipe assembly.
Torque: 43N. m
6. Install intermediate exhaust pipe assembly
Using the new gasket, install the intermediate exhaust pipe to the front exhaust pipe.
Torque: 44N. m
7. Install tail exhaust pipe assembly
Using the new gasket, install the tail exhaust pipe to the intermediate
exhaust pipe. See (Figure 117).
Torque: 43N. m
8. Check exhaust for leakage

Chapter 6 Cooling System Inspection
(MR7131A, MR7151A, MR7161A)
Section 1 System Check
1. Check the cooling system for leakage. See (Figure 118)
(a) Fill coolant into radiator. Install the tester onto the radiator cap port.
(b) Start engine.
(c) The water pump pressure is 118Kpa. Check the pressure and ensure the
pressure will not drop. If the pressure drops, check the port, radiator and
water pump for leakage. If there is no leakage, check the heat exchanger,
cylinder block and cylinder head.
2. Check the engine coolant level in the reservoir.
The coolant level should be between low and full marks.
3. Check coolant quality
(a) Remove radiator cap.
To avoid being scalded, do not remove radiator cap while the engine and
radiator are still hot, as fluid and steam can be sprayed under pressure.
(b) There should not be excessive deposits of rust or scale around the radiator,
and the coolant should be free from oil.
(c) Reinstall the radiator cap.
4. Thermostat
Hint:
The thermostat temp indicates the valve opening temperature.
See (Figure 119).
(a) Immerse the thermostat in water and gradually heat the water.
(b) Check the valve opening temperature. Valve opening temperature: 80 -- 84°C
(c) Check the valve lift. See (Figure 120, Figure 121). Valve lift: 8mm or mor at
95°C
(d) Check the thermostat is fully closed when the thermostat is at low temperature
( 77°C).
5. Radiator cap valve
Standard opening pressure: 93-123kpa
Minimum opening pressure: 78kpa
If the opening pressure is less thanminimum, replace the radiator cap.
