engine coolant CHRYSLER 300 SRT 2007 1.G User Guide

humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check coolant freeze point in the radiator and in the
coolant recovery bottle. If antifreeze needs to be
added, contents of coolant recovery bottle must also be
protected against freezing.
•If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
•Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine, which contains
aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component, which may cause heat
damage or mechanical wear.

Engine Oil (6.1 Liter) For best performance and maximum protection under all types of operating
conditions, the manufacturer only recommends full synthetic engine oils that
meet the American Petroleum Institute (API) categories of SM or SM/CF, and
meet the requirements of DaimlerChrysler Material Standard MS-10725. The
manufacturer recommends the use of a full synthetic engine oil, such as Mo-
bil 1SAE 0W-40 or equivalent. For additional information, refer to the “En-
gine Oil Selection” and “Engine Oil Viscosity (SAE Grade)” in the “Mainte-
nance Procedures” section of this manual.

314 MAINTAINING YOUR VEHICLE

•Taxi, police, or delivery service (commercial ser-
vice).
•Off-road or desert operation.
NOTE:IfANYof these apply to you, then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first, and follow the maintenance rec-
ommendations in Schedule “B” in this section.
NOTE:IfANYof these apply to you, then flush and
replace the engine coolant every 102,000 miles (170 000
km) or 60 months, whichever comes first, and follow the
maintenance recommendations in Schedule “B” in this
section.
NOTE:Most vehicles are operated under the conditions
listed for ScheduleB.
Second is Schedule“A.”It is for vehicles that are not
operated under any of the conditions listed under Sched-
uleB.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
NOTE:Under no circumstances should oil change
intervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•
Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.

proper fit.
At Each Oil Change
•
Change the engine oil filter.
