Dodge Challenger SRT 392 2015 Operating Information Manual page 275

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 expansion bottle.
• Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle must
also be protected against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks.
• Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.
• Make sure that the coolant expansion 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.

• Do not change the thermostat for Summer or
Winter operation. If replacement is ever nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the "Service and
Warranty Handbook" for the proper mainte-
nance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake tempera-
tures, excessive lining wear, and possible
brake damage. You would not have your full
braking capacity in an emergency.
Master Cylinder — Brake Fluid Level
Check
Check the fluid level in the master cylinder
immediately if the "Brake Warning Light" indi-
cates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the "MAX" mark on the side of the master
cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid res-
ervoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. How-
ever, low fluid level may be caused by a leak
and a checkup may be needed.
Use only manufacturer's recommended brake
fluid. Refer to "Fluids, Lubricants, and Genuine
Parts" in "Maintaining Your Vehicle" for further
information.
