REMOVAL
1.Disconnect the vacuum hose (A).
2.Remove the PCV Valve (B).
INSTALLATION
Install the PCV valve and tighten to the specified torque.
PCV Valve installation : 7.8 ~ 11.8 N·m (0.8 ~ 1.2 kgf·m, 5.8 ~ 8.7lbf·ft)
INSPECTION
1.Remove the PCV valve.
2. Insert a thin stick(A) into the PCV valve(B) from the threaded side to check that the plunger moves.
3. If the plunger does not move, the PCV valve is clogged. Clean it or replace.

DESCRIPTION

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Disconnect the vacuum hose from the throttle body, and connect a vacuum pump to the vacuum hose.
2. Check the following points when the engine is cold [engine coolant temperature 60°C(140°F) or below] and when it
is warm [engine coolant temperature 80°C(176°F) or higher].
WHEN ENGINE IS COLD
Engine operating condition Applied vacuumResult
Idling 50 kPa
(7.3 psi) Vacuum is held
3,000 rpm
WHEN ENGINE IS WARM Engine operating condition Applied vacuumResult
Idling 50 kPa
(7.3 psi) Vacuum is held
Within 3 minutes after engine start at 3,000
rpm Try to apply vacuum
Vacuum is released
After 3 minutes have passed after engine
start at 3,000 rpm 50 kPa
(7.3 psi) Vacuum will be held momentarily,
after which, it will be released

Canister

2007 > 2.7L V6 GASOLINE >
REMOVAL
1.Disconnect the vacuum hoses (A,B).
2.Remove the canister assembly (A) with unscrewing the two mounting bolts (B).
3.Open the canister upper cover (A) with unfastening the four bolts (B) and remove the canister (C) from the canister
lower cover (D).

INSTALLATION
Install the canister according to the reverse order of "REMOVAL" procedure.
INSPECTION
1.Look for loose connections, sharp bends or damage to the fuel vapor lines.
2. Look for distortion, cracks or fuel damage.
3. After removing the canister, inspect for cracks, damage or saturated canister.
