4. CHECK AIR INLET LINE
(a) Disconnect the air inlet line hose from the charcoal
canister.
(b) Check that air can flow freely into the air inlet line.
If air cannot flow freely into the air inlet line, repair or
replace it.
(c) Reconnect the air inlet line hose to the charcoal
canister.
5. VISUALLY INSPECT HOSES, CONNECTORS AND
GASKETS
(a) Check for cracks, leaks or damage.
HINT:
Removal or problems with the engine oil dipstick, oil
filler cap, PCV hose and other components may
cause the engine to run improperly. Disconnection,
looseness or cracks in the parts of the air induction
system between the throttle body and cylinder head
will allow air suction and cause the engine to run
improperly.
If necessary, replace any damaged parts.

COOLING SYSTEM
ON-VEHICLE INSPECTION
1. INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator cap while the engine and
radiator are still hot. Pressurized, hot engine coolant
and steam may be released and cause serious
burns.
NOTICE:
Before performing each inspection, turn the A/C
switch OFF.
(a) Fill the radiator with coolant and attach a radiator
cap tester.
(b) Warm up the engine.
(c) Using a radiator cap tester, increase the pressure
inside the radiator to 118 kPa (1.2 kgf/cm
2, 17 psi),
and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and
water pump for leaks. If no external leaks are found,
check the heater core, cylinder block and cylinder
head.
2. INSPECT ENGINE COOLANT LEVEL IN RESERVOIR
(a) Check that the engine coolant level is between the
LOW and FULL lines when the engine is cold.
If the engine coolant level is low, check for leaks and
add "TOYOTA Super Long Life Coolant" or similar
high quality ethylene glycol based non-silicate, non-
amine, non-nitrite and non-borate coolant with long-
life hybrid organic acid technology to the FULL line.
NOTICE:
Do not substitute plain water for engine coolant.
3. INSPECT ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
Do not remove the radiator cap while the engine
and radiator are still hot. Pressurized, hot
engine coolant and steam may be released and
cause serious burns.
(b) Check if there are any excessive deposits of rust or
scales around the radiator cap and radiator filler
hole. Also, the coolant should be free of oil.
If excessively dirty, clean the coolant passage and
replace the coolant.
(c) Install the radiator cap.

2. REMOVE OIL PUMP COVER
(a) Remove the 8 bolts, oil pump cover and oil pump
rotor set.
INSPECTION
1. INSPECT OIL PUMP RELIEF VALVE
(a) Coat the relief valve with engine oil and check that it
falls smoothly into the valve hole under its own
weight.
If the valve does not fall smoothly, replace the relief
valve. If necessary, replace the oil pump assembly.
2. INSPECT OIL PUMP ROTOR SET
(a) Install the rotors to the timing chain cover with the
rotors' marks facing outward. Check that the rotors
rotate smoothly.
(b) Check the tip clearance.
(1) Using a feeler gauge, measure the clearance
between the drive and driven rotors, as shown
in the illustration.
Tip clearance
If the clearance is greater than the maximum,
replace the drive and driven rotors.
(c) Check the side clearance.
(1) Using a feeler gauge and precision
straightedge, measure the clearance between
the rotors and precision straightedge, as shown
in the illustration.
Side clearance
If the side clearance is greater than the
maximum, replace the timing chain cover.
