INSTALLATION SERVICE POINT

.

>>A<< FUEL HIGH-PRESSURE HOSE INSTALLATION

CAUTION

Be careful not to allow any engine oil to enter the fuel rail.
1. When connecting the fuel high-pressure hose to the fuel rail, 

apply a small amount of new engine oil to the O-ring and 
then insert the fuel high-pressure hose, being careful not to 
damage the O-ring.

2. While turning the fuel high-pressure hose to the left and 

right, install it to the fuel rail.

3. Check that the injector turns smoothly. If it does not turn 

smoothly, the O-ring may be trapped. Remove the fuel 
high-pressure hose and then re-insert it into the fuel rail and 
check again.

INSPECTION

M1151003100597

Check the following points; replace the part if a problem is 
found.

Intake Manifold Check

1. Check for damage or cracking of any part.
2. Clogging of the negative pressure (vacuum) outlet port, or 

clogging of the exhaust gas recirculation passages.

3. Using a straight edge and feeler gauge, check for distortion 

of the cylinder head installation surface.

Standard value: 0.15 mm (0.006 inch) or less 
Limit: 0.20 mm (0.008 inch)
