tire type DODGE CHARGER SRT 2008 6.G User Guide

Inspect belts for evidence of cuts, cracks, glazing, or
frayed cords and replace if there is indication of damage
that could result in belt failure. Also, check belt routing to
make sure there is no interference between the belts and
other engine components. See your authorized dealer for
service.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emissions control. New plugs should be
installed at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Malfunctioning spark plugs can damage the cata-
lytic converter. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the proper type of spark plug for
use in your vehicle.
Engine Air Cleaner Filter
Refer to the Maintenance Schedule in Section 8 for engine
air cleaner filter maintenance intervals.
NOTE:Be sure to follow the “dusty or off-road condi-
tions” maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses, etc) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc) removed. Failure to do so can result in
serious personal injury.

Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin todrain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush, and Refill
The system should be drained, flushed, and refilled at the
intervals shown in the Maintenance Schedule in Section
8.
If the solution is dirty or contains a considerable amount
of sediment, clean and flush with a reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze solution.
Selection of Coolant
Use only the manufacturer’s recommended coolant. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct coolant type.
