them and apply grease to prevent corrosion.
Check that the transmission shifts into gear
smoothly.
Inspect for fuel leaks. Turn the ignition switch ON(ll) {do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation two or three times, then
check for fuel leakage at any point in the fuel line.
Refillthe engine with engine oil (see page 8-5).
Refill the transmission with fluid (see page 13-3).
Refill the radiator with engine coolant, and bleed
air from the cooling system with the heater valve
open (see page 10-6).
Perform the engine control module (ECM) idle learnprocedure (see page 11-139).
Inspect the idle speed (see page 1 1-138).
Inspect the ignition timing (see page 4-17).
Check the wheel alignment {see page 18-4).
Enter the anti-theft code for the radio, then enter
the customer's radio station presets.

WEC Rocker Arms Test (cont'dl
'10. Loosen the valve on the regulator, and apply thespecified air pressure.
Specified air pressure:
290 kPa 13.0 kgt/cm', 42 psi)
NOTE: lf the synchronizing piston does not moveafter applying air pressure; move the primary orsecondary rocker arm up and down manually byrotating the crankshaft clockwise.
11. With the specified air pressure applied, move theintake primary rocker arm (A)forthe No, 1 cylinder.The primary rocker arm and secondary rocker arm(B) should move together.
lf the intake secondary rocker arm does not move,
remove the primary and secondary rocker arms asan assembly, and check that the pistons in theprimary and secondary rocker arms move
smoothly. lf any rocker arm needs replacing,
replace the primary and secondary rocker arms asan assembly, and test.
Remove the special tools.
Tighten the camshaft holder mounting bolts lo22N m 12.2 kgf.m, 16 lbf.ft).

VTG Actuator Inspection
'11. Remove the cylinder head cover (see page 6-22lr.
2. Remove the auto-tensioner (see page 6-19).
3. Loosen the rocker arm adjusting screws lsee step 2on page 6-26).
4. Remove the camshaft holder (see step 3 on page 6-
26t.
5. Remove the intake camshaft.
6, Check that the variable valve timing control (VTC)
actuator is locked by turning the VTC actuator
clockwise and counterclockwise. lf the VTC actuatoris not locked, replace the VTC actuator.
7. Seal the advance holes (A)and retard holes (B) in
the No. 1 camshaft journal with tape.
Punch a hole through the tape over one of theadvance holes.

9. Apply air to the advance hole to release the lock.
Check that the VTC actuator moves smoothly. lf the
VTC actuator does not move smoothly, replace the
VTC acluator.

Valve Glearance Adiustment
NOTE: Adjust the valves only when the cylinder head
temperature is less than 100'F (38'C).
1. Remove the cylinder head cover (see page 6-22).
2. Set the No. 1 piston at top dead center (TDC). The
punch mark (A) on the variable valve timing control
(VTC) actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
exhaust camshaft sprocket.
