3. If the clearance is outside the standard value, check for air trapped in the brake 
line and thickness of the disc brake pad. And then adjust and replace defective 
parts as required.  
4. Return the carpet etc. to its original position.  BRAKE BOOSTER OPERATING TEST 1. For simple checking of the brake booster operation, carry out the following 
tests: 
1. Run the engine for one or two minutes, and then stop it. If the pedal 
depresses fully the first time but gradually becomes higher when 
depressed succeeding times, the booster is operating properly. If the pedal 
height remains unchanged, the booster is defective. Go to step 2.

2. With the engine stopped, step on the brake pedal several times. Then step 
on the brake pedal and start the engine. If the pedal moves downward 
slightly, the booster is in good condition. If there is no change, the booster 
is defective. Go to step 3.

3. With the engine running, step on the brake pedal and then stop the engine. 
Hold the pedal depressed for 30 seconds. If the pedal height does not 
change, the booster is in good condition, if the pedal rises, the booster is 
defective.

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.

3. With the engine idling, change the engine load (shift from N to D range, for 
example) to make sure that there is no change in the level of abnormal noise. 
If there is a change in the level of abnormal noise, suspect a tapping noise due 
to worn crankshaft bearing or connecting rod bearing (In this case, the lash 
adjuster is in good condition.). 
4. After completion of warm-up, run the engine at idle to check for abnormal 
noise. 
If the noise is reduced or disappears, clean the lash adjuster (Refer to 
ROCKER ARMS AND CAMSHAFT
 ). As it is suspected that the noise is 
due to seizure of the lash adjuster. If there is no change in the level of the 
abnormal noise, proceed to step 5. 
5. Run the engine to bleed the lash adjuster system (Refer to LASH ADJUSTER 
CHECK
 .).  
6. If the abnormal noise does not disappear after air bleeding operation, clean the 
lash adjuster (Refer to ROCKER ARMS AND CAMSHAFT
 ).  
Bleeding lash adjuster system 1. Check engine oil and add or change oil if required. NOTE: Parkin
g the vehicle on a 
grade for a lon
g time ma
y decrease 
oil in the lash adjuster, causing air to enter the high 
pressure chamber when starting the engine.
NOTE: After parking for many hours, oil may run out from the oil 
passage and take time before oil is supplied to the lash 
adjuster, causing air to enter the high pressure chamber.
NOTE: In the above cases, abnormal noise can be eliminated by 
bleeding the lash adjuster system.
NOTE: If the engine oil level is low, air is sucked from the oil

CIRCUIT OPERATION Power is supplied to the radio and CD player or radio, CD player and CD changer 
when the ignition switch is in the "ACC" position or "ON" position. When the 
ignition is switched on, the radio and CD player or radio, CD player and CD 
changer or radio, CD player and CD changer will return to the previous state when 
the ignition was switch off at the last time. TECHNICAL DESCRIPTION (COMMENT) The cause is probably a faulty radio and CD player or radio, CD player and CD

between the station transmitter and the vehicle), and noise will appear. < This 
is called first fading, and gives a steady buzzing noise. >  
3. If a direct signal hits the antenna at the same time as a signal reflected by 
obstructions such as mountains or buildings, interference of the two signals 
will generate noise. When moving, noise will appear each time the vehicle's 
antenna passes through this kind of obstructed area. The strength and interval 
of the noise varies according to the signal strength and the conditions of 
deflection. < This is called multipath noise, and is a repetitive buzzing. >

4. Since FM stereo transmission and reception has a weaker field than monaural, 
it is often accompanied by a hissing noise. 
After taking measures to prevent the noise, check that no noise occurs. 
5. Change to a different station with a stronger wave to boost resistance to 
interference.  
6. Su

Q: Is the wiring harness between radio and CD player or radio, CD player 
and CD changer connector C-105 (terminal 21) and the battery in good 
condition?  
YES: Repair or replace the radio and CD player or radio, CD player and 
CD changer. Check that a memory is retained.  
NO: Repair the wiring harness. Check that a memory is retained.  
INSPECTION PROCEDURE 23: CD can not be Inserted. DIAGNOSIS 
STEP 1. Check that a CD has been already loaded. 
Q: Has a CD been already loaded?  
YES: Take out the CD (If the CD can not be ejected, refer to 
INSPECTION PROCEDURE 27
 ). Check that a CD can be inserted.  
NO: Go to Step 2.  
STEP 2. Check how a CD is inserted. 
Ensure that the ignition switch is at 'ACC' or 'ON'. 
Q: If you try to load the CD, does the CD stops halfway and then rejected?
YES: Refer to INSPECTION PROCEDURE 27
 .  
NO: Go to Step 3.  
STEP 3. Check after the CD is loaded. 
NOTE: If you try to load a CD when the ignition switch is at the 
positions other than 'ACC' or 'ON,' the CD will not be 
inserted completely and then rejected.
NOTE: Even though the CD is loaded, 'E01' (vehicles with 
center display low type) or 'ERROR 01' (vehicles with 
center display middle type) sometimes displayed with 
the CD rejected because of vibration/shock or dew on
