2004 DODGE VIPER coolant temperature

Trunk Ajar Light
This light indicates that the trunk is not latched.
Engine Coolant Temperature Light
A red LED light on the Coolant Temperature
gauge will illuminate to warn of an overheated
engine coolant condition.
Low Oil Pressure Light
A red LED light on the Oil Pressure gauge will
illuminate to indicate low engine oil pressure. The
light should come on briefly as a bulb check when the
engine is first started. If the light stays on or comes on
while driving, stop the vehicle and shut off the engine.
DO NOT operate the vehicle until the cause is corrected.
NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked under
the hood.
Charge System Light
A red LED light on the Voltage gauge will illumi-
nate when there is a charging system malfunction
or a possible accessory drive belt failure.
CAUTION!
The accessory belt also drives the water pump.
Operating the vehicle with a failed belt can cause
engine overheating and possible severe engine dam-
age.
Fog Light ON Indicator
This light indicates that the fog lights are on.

Gauges
Tachometer
This gauge shows engine speed in revolutions-
per-minute (RPM) times 1,000. Avoid excessive
engine speeds in any part of the red warning
zone, particularly when driving downhill or in
lower gears.
Coolant Temperature Gauge
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temperatures when driving in hot weather, up
mountain grades, or in heavy stop and go
traffic. If the red LED light turns on, stop the vehicle and
turn off the engine until the cause is corrected.
Oil Temperature Gauge
This gauge shows the oil temperature. The
gauge pointer will likely show higher tempera-
tures when driving in hot weather, up moun-
tain grades, or in heavy stop and go traffic. If
the red LED light turns on, stop the vehicle and turn off
the engine until the cause is corrected.
Oil Pressure Gauge
This gauge shows engine oil pressure when the
engine is running. The pressure will vary with
engine speed, oil viscosity, and engine tem-
perature. Oil pressures will be higher as the
engine is warming up. The normal operating pressure is
between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, turn off the engine until
the cause is corrected.

²In city trafficÐWhile moving, shift into the highest
gear possible to reduce engine RPM.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the cooling system and turning off the A/C removes this
heat. You can also turn the Temperature control to
maximum heat, the Mode control to floor, and the fan
control to High. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant.
If your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to
call a service center for service. If you decide to look
under the hood yourself, see Section 7 of this
manual. Follow the warnings under the Radiator
Cap paragraph.
WHAT TO DO IN EMERGENCIES 133
6

Adding Coolant
DO NOT remove the pressure cap when checking cool-
ant. When adding coolant or refilling system, a 50%
solution of ethylene glycol antifreeze coolant in water
should be used. Higher concentrations (not to exceed
65%) are required if temperatures below ±37ÉF are antici-
pated.
Use only high purity water such as distilled or deionized
water when mixing the water / antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
NOTE:It is the owner's responsibility to maintain the
proper level of protection against freezing according to
the temperatures occurring in the area where the vehicle
is operated.WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool overheated engine. The coolant is under pres-
sure and severe scalding could result.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
The pressure cap should be inspected and cleaned if there
is any accumulation of foreign material on the sealing
surfaces.
168 MAINTAINING YOUR VEHICLE

Check the battery every 4 to 6 weeks to ensure that the
voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below
12.40, follow the battery recharge procedure in the
Service Manual.
²Check that the radiator coolant level of protection is to
at least -20ÉF (-29ÉC).
²Block the wheels. Do not apply the Parking Brake.
²Make sure that all tires are inflated to the optimum
pressure, (29 PSI).
²Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
²For long term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
²Move the wiper blades away from the windshield.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the trunk, hood, doors, windows and
convertible top are completely closed.
2. Make sure that remote transmitter is operating and
that the battery is good.
3. Make sure that the hood, trunk and door switches are
in adjustment. Perform the quick system check which
follows.
Use the remote transmitter to set the alarm. If the alarm
SET light comes on and flashes, the system is operating
properly. If not, there is a problem with a switch or the
system. See your dealer for service.
