2004 ENGINE COOLING
Specifications & Drive Belt Routing - Endeavor
COOLING SYSTEM BLEEDING 1. Using LLC Changer (MB991871), refill cooling system with appropriate
mixture between 30-60% anti-freeze (depending on weather conditions). See
Fig. 1
. Typically a solution of 50% anti-freeze and 50% distilled water is
sufficient for most areas. A solution of 50% anti-freeze and 50% water has a
freezing point of -32.8°F (-31°C).
2. Reinstall the radiator cap.
3. Start the engine and let it warm up until the thermostat opens.
4. After repeatedly revving the engine up to 3000 RPM several times, shut off the
engine.
5. Remove the radiator cap after engine has become cold, completely fill the
radiator with coolant. Reinstall the cap.
6. Ensure coolant in the reserve tank is between the FULL and LOW marks. Add
coolant if necessar
y.
CAUTION: DO NOT use alcohol or methanol anti-freeze or any
engine coolants mixed with alcohol or methanol anti-
freeze. The use of an improper anti-freeze can cause
corrosion of the aluminum components.
CAUTION: DO NOT overfill the reserve tank.

4. Hold Microphone (part of Belt Drive Meter Set) (MB991668) near the center
of the drive belt between the pulleys away from the rear surface of the belt and
perpendicular to the belt (no more then 15 degrees in either direction). See Fi
g.
3 and Fig. 4
.
5. Gently tap the middle of the belt between the pulleys with your finger, and
check that the vibration frequency of the belt is within specification. See Fig. 3
and Fig. 4
. See DRIVE BELT ADJUSTMENT SPECIFICATIONS
table.
CAUTION: Temperature of the surface of the belt should be
as close possible to underhood temperature.
CAUTION: DO NOT let contaminants such as water or oil get
onto the microphone. If strong gusts of wind
blow against the microphone or if there are any
loud sources of noise nearby, the values
measured by the microphone may not
correspond to actual values. DO NOT take
