LUBRICATION
SERVICE INTERVALS
Check fluid at every oil change.
CHECKING FLUID LEVEL
Check fluid level with engine stopped and fluid hot or cold.
Fluid level must be at "FULL-HOT" or "FULL-COLD" mark on dipstick. On
models with remote reservoir, keep fluid level 0.5-1.0" from top of
reservoir with wheels turned fully to left.

REFILLING & BLEEDING SYSTEM
1) Fill reservoir to correct level. Operate engine until
fluid reaches normal operating temperature. Stop engine. Add fluid (if
necessary). Turn wheels to full left position. Add fluid to reservoir
to fill to "FULL-COLD" mark on dipstick.
2) Start and operate engine at fast idle. Recheck reservoir
level. Add to "FULL-COLD" mark on dipstick. Turn wheels from side to
side without contacting stops. Maintain fluid level just above pump
body.
3) When air is removed, return wheels to straight-ahead
position. Operate engine 2-3 minutes. Stop engine. Road test vehicle.
Recheck fluid level. Level should be at "FULL-HOT" position after
system has stabilized. Add fluid (if necessary). DO NOT overfill.

1988 Starters
BOSCH & MITSUBISHI
Jeep with 4.0L 6-Cyl.
DESCRIPTION
NOTE: Information on Jeep 2.5L starter not available from
manufacturer.
Bosch and Mitsubishi use a permanent magnet starter. A
planetary gear train transmits power between starter motor and pinion
shaft. The starter magnetic field is produced by 6 permanent magnets.
The Mitsubishi starter is a 12-volt unit that has the solenoid mounted
on the starter housing. See Fig. 3.
TROUBLE SHOOTING
NOTE: See the TROUBLE SHOOTING - BASIC PROCEDURES article
in the GENERAL TROUBLE SHOOTING section.
TESTING (ON VEHICLE)
AMPERAGE DRAW TEST
NOTE: Engine should be at operating temperature before performing
this test. Heavy duty oil or a tight engine will increase
starter draw amperage. Tests are performed with standard
volt-ammeter tester.
1) Connect tester and remote starter switch. Set voltmeter
selector to 16-volt position. Select function to 0-500-amp scale.
Connect voltmeter leads to corresponding polarity battery terminals.
2) Connect ammeter leads to corresponding battery terminals.
Disconnect coil wire from distributor cap and attach to ground to
prevent engine from starting.
3) Crank engine and observe exact reading on voltmeter. Stop
cranking engine. Turn tester control knob clockwise until voltmeter
reads exactly the same as when engine was cranked with remote starter
switch. Ammeter should indicate starter draw of about 150-220 amps.
STARTER RESISTANCE TEST
Use a voltmeter that will indicate tenths of a volt. Without
disconnecting any starter connections, perform the following
resistance tests:
1) Perform following tests with engine cranking and all
terminals connected. Connect a voltmeter at following locations:
* Positive lead to battery positive post and negative lead
to battery terminal on starter.
* Positive lead to starter housing and negative lead to
negative post on battery.
* Positive lead to battery negative post and negative lead
to battery cable connector on engine block.
2) Each of these 3 connections should show a voltmeter
