GENERAL INFORMATION
VEHICLE IDENTIFICATION NUMBER (VIN)
FLUIDS-LUBRICANTS
Transmission-Transfer Case Fluid
Mercon automatic transmission fluid is now recommended for use in all 1987-88 Eagle automatic transmissions. This same fluid is also recommended for use in transfer case Models 119 and 129.
Mercon is compatible with Dexron II and can be used to top off a transmission/transfer case previously filled with a Dexron-type fluid.
The new Mercon fluid will be the only fluid supplied by your PDC when existing stocks of the current fluid are used up.
Axle Lubricants
An SAE 75W-90, API grade GL 5 axle gear lubricant will be used for all standard duty applications.
A new synthetic-type, SAE 80W-140 hypoid gear lubricant will be used for trailer towing applications. The new synthetic is the only lubricant recommended for trailer tow applications. Part number for the new lubricant is 8982 200 945.
The Trac-Lok axle in 1988 models requires an additive, part number 8983 100 003. The additive is compatible with the standard and new synthetic axle lubricants.
EMISSION MAINTENANCE TIMER AND INDICATOR LIGHT
1988 Eagle 49-State and Canada models are equipped with an emission maintenance timer and indicator light. The timer and light are used to alert the owner when oxygen sensor-PCV valve replacement and other scheduled emission maintenance is required.
The indicator light is located in the instrument cluster. The timer is mounted on the dash panel at the passenger side of the vehicle.
The timer (A) is operated by the ignition system. It activates (flashes) the indicator light when vehicle mileage reaches the scheduled maintenance interval of 133,000 kilometers (82,500 miles).
Emission Maintenance Timer Service
The life cycle of the timer coincides with the emission maintenance interval of 133,000 kilometers (82,500 miles). The timer can not be reset after reaching this mileage interval. The timer can only be replaced or disconnected.
NOTE: The oxygen sensor and timer are interdependent. If the timer should fail prematurely, the oxygen sensor must be replaced along with the timer. This is important in preserving the correct sensor replacement interval and ensuring proper engine performance.
Emission Maintenance Timer Replacement
Remove the screws attaching the maintenance timer (C) to the dash bracket and remove the timer from the bracket.
NOTE: The maintenance timer is mounted on the dash panel to the right of the steering column.
Disconnect the timer electrical wires (D) and remove the timer from the vehicle.
Connect the electrical wires to the replacement timer.
Position the timer on the dash bracket and install the timer attaching screws.
