11. Turn (or have an assistant turn) the steering wheel slightly in both directions and release quickly
while watching the pressure gauge.
zThe pressure reading should move from the normal back pressure reading and snap
back as the steering wheel is released.
z If the pressure returns slowly or sticks, the rotary valve in the steering gear is sticking or
the steering column is binding. Check the steering column and linkages before servicing
the steering gear.
Tie- Rod Articulation Torque
1. NOTE: This check may be done with the steering gear on or off the vehicle.
Disconnect the tie- rod end from the front wheel spindle. For additional information, refer to
Section 211 - 02 .
2. Move the front wheel spindle tie- rod back and forth three times.
3. Hook the special tool 211- 034 (T74P-3504-Y) over the tie-rod end or the threaded portion of the
front wheel spindle tie- rod and measure the force required to move the front wheel spindle tie-
rod. Refer to Tie- Rod Articulation Torque in General Specifications in this section.
4. If the force required to move the front wheel spindle tie- rod does not meet the specifications,
install a new front wheel spindle tie- rod. For additional information, refer to Section 211 - 02 .
Steering Gear Valve 1. With the vehicle in motion, place the transmission in NEUTRAL and turn the engine OFF. zIf the vehicle does not pull with the engine OFF, install a new steering gear. For
additional information, refer to Section 211 - 02 .
2. If the vehicle pulls with the engine OFF, cross- switch the front wheels.
3. If the vehicle pulls to the opposite side, cross- switch the front and rear wheels on the same side.
4. If the vehicle pull direction does not change, check the front suspension components, wheel alignment and frame alignment. For additional information, refer to Section 204 - 00 or frame
dimensions manual. Klj . 10 ba

DESCRIPTION AND OPERATION
Steering Column Switches
The steering column switches system consists of the following components:
zmultifunction switch (13K359)
z key release button (manual transmission only) (3F527)
z ignition switch (11572)
The integrated multifunction switch is mounted to the LH side of the steering column and controls the
turn signals, hazard flasher, windshield wiper/washer control, and headlamp dimmer/flash- to-pass.
The key release button is equipped with manual transmissions only.
The ignition switch is mounted below the steering column and is activated by rotating the key lock
cylinder on the steering column. SECTION 211-

Component Tests
Engine Oil Leaks
NOTE:
When diagnosing engine oil leaks, the source and location of the leak must be positively
identified prior to repair.
Prior to carrying out this procedure, clean all sealing surface areas with a suitable solvent to remove all
traces of oil.
Engine Oil Leaks— Fluorescent Oil Additive Method
Use the UV Leak Detector Kit to carry out the following procedure for oil leak diagnosis. 1. Add gasoline engine oil dye. Use a minimum 14.8 ml (0.5 ounce) to a maximum 29.6 ml (1 ounce) of fluorescent additive to all engines. If the oil is not premixed, fluorescent additive must
first be added to crankcase.
2. Run the engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using the UV Leak Detector Kit. A clear bright yellow or orange area will identify the leak. For
extremely small leaks, several hours may be required for the leak to appear.
Leakage Points— Underhood
Examine the following areas for oil leakage:
zvalve cover gaskets z
Slipping
transmission. z
Refer to the appropriate section
in Group 307 for the procedure.
z Malfunctioning
valve tappet or lash
adjuster. z
INSTALL a new valve tappet or

Oil leaks at crimped seams in sheet metal parts and cracks in cast or stamped parts can be detected
when using the dye method.
Compression Test— Compression Gauge Check
1. Make sure the oil in the crankcase is of the correct viscosity and at the correct level and that the battery (10655) is correctly charged. Operate the vehicle until the engine is at normal operating
temperature. Turn the ignition switch to the OFF position, then remove all the spark plugs
(12405).
2. Set the throttle plates in the wide- open position.
3. Install a compression gauge such as the Compression Tester in the No. 1 cylinder.
4. Install an auxiliary starter switch in the starting circuit. With the ignition switch in the OFF position, and using the auxiliary starter switch, crank the engine a minimum of five compression
strokes and record the highest reading. Note the approximate number of compression strokes Klj . 7 ba

Valve Train Analysis—
Engine Running
z Start the engine and, while idling, check for correct operation of all parts. Check the following:
Valve Train Analysis— Engine Running, Valves and Cylinder Head
z Check for plugged oil drain back holes.
z Check for missing or damaged valve stem seals or guide mounted valve stem seals.
z Check for a plugged oil metering orifice in the cylinder head oil reservoir (4.6L engine only).
If insufficient oiling is suspected, check oil passages for blockage, then accelerate the engine to 1,200
rpm with the transmission in NEUTRAL and the engine at normal operating temperature. Oil should
spurt from the rocker arm oil holes such that valve tips and camshaft roller followers are well oiled.
With the valve covers (6582) off, some oil splash may overshoot camshaft roller followers.
Valve Train Analysis— Engine Running, Camshaft Lobe Lift— OHC Engines
Check the lift of each camshaft lobe in consecutive order and make a note of the readings. 1. Remove the valve covers.
2. Remove the spark plugs.
3. Install the Dial Indicator Gauge with Holding Fixture so the rounded tip of indicator is on top of the camshaft lobe and on the same plane as the valve tappet.
4. Rotate the crankshaft using a breaker bar and socket attached to the crankshaft pulley retainer bolt. Rotate the crankshaft until the base circle of the camshaft lobe is reached.
5. Zero the dial indicator. Continue to rotate the crankshaft until the (1) high- lift point of the
camshaft lobe is in the fully- raised position (highest indicator reading).
6. To check the accuracy of the original indicator reading, continue to rotate crankshaft until the (2) base circle is reached. The indicator reading should be zero. If zero reading is not obtained,
repeat Steps 1 through 6.
7. NOTE: If the lift on any lobe is below specified service limits, install a new camshaft, and new
camshaft roller followers.
Remove the Dial Indicator Gauge with Holding Fixture.
8. Install the spark plugs. Klj . 15 ba
