Anticorrosion / antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that
anticorrosion / antifreeze coolant used in
such engines be specifically formulated to
protect the aluminum parts. (Failure to use
such anticorrosion / antifreeze coolant will
result in a significantly shortened service
life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz Anticorrosion / Antifreeze
agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion / antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to your authorized Mercedes-Benz
Light Truck Center for service.

ON-VEHICLE TESTING
WIRING CONTINUITY
1. Connect voltmeter between generator B+ terminal and ground. Voltmeter should indicate battery voltage.
If battery voltage is not indicated, check battery and check wiring between generator and battery for
corrosion, loose terminals, etc.
2. Turn ignition on and ensure instrument cluster charge indicator light (battery symbol) comes on. If light
does not come on, check wiring between generator and warning light, including indicator bulb.
GENERATOR OUTPUT
1. Ensure connections at battery and generator are clean and tight. Ensure generator, engine and body are
properly grounded. Ensure generator drive belt is properly adjusted and in good condition.
2. Connect load tester/ammeter as per tester manufacturer's instructions. Connect voltmeter leads to battery
terminals. See Fig. 9
. Start engine and run at 2200 RPM for V6 or 2500 RPM for V8. Adjust load tester
to obtain maximum generator output. DO NOT allow voltage to drop to less than 12.7 volts.
3. Maximum generator output should be within a few amps of generator rated output stamped on generator.
If output is not within a few amps of generator rated output, check generator diodes. See DIODE TEST
.
Replace
generator as necessary.
