2004 MITSUBISHI ENDEAVOR radiator cap

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.

DIAGNOSI
S
STEP 1. Remove the radiator cap and check for coolant contamination.
Q: Is the coolant contaminated with rust and oil?
YES: Replace it. Refer to ENGINE COOLANT REPLACEMENT
.
NO: There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the gauge indicator stops moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93 - 123 kPa (14 - 18 psi)
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an
improper reading.

Q: Does the reading remain at or above the minimum limit?
YES: Go to Step 3.
NO: Replace the radiator cap. Then go to Step 5 .
STEP 3. Check thermostat operation.
Refer to INSPECTION
.
Q: Does the thermostat operate correctly?
YES: Go to Step 4.
NO: Replace the thermostat, then go to Step 5 .
STEP 4. Check the drive belt for slippage or damage.

3. Replace the radiator cap if the reading does not remain at or above the limit.
ENGINE COOLANT REPLACEMENT 1. Drain the water from the radiator, heater core and engine after unplugging the
radiator drain plug and removing the radiator cap.
2. Drain the water in the water jacket by unplugging the drain plug of the cylinder
block. For the right bank side on AWD vehicles, drain the engine coolant from
the water feed tube assembly of the transfer box.
3. Remove the radiator condenser tank assembly and drain the coolant.
4. Drain the coolant then clean the path of the coolant by injecting water into the
radiator from the radiator cap area.
WARNING:When removing the radiator cap, use care to avoid
contact with hot coolant or steam. Place a shop
towel over the cap and turn the cap
counterclockwise a little to let the pressure escape
through the vinyl tube. After relieving the steam
pressure, remove the cap by slowly turning it
counterclockwise.

11. After repeatedly revving the engine up to 3,000 r/min several times, stop the
engine.
12. Remove the radiator cap after the engine has cooled, and pour in coolant up to
the brim. Reinstall the cap.
13. Add coolant to the radiator condenser tank assembly between the "FULL" and
"LOW" mark if necessary. ENGINE COOLANT CONCENTRATION TEST Refer to RECOMMENDED LUBRICANTS AND LUBRICANT CAPACITIES
.
FAN CONTROL MODULE CHECK 1. Remove the fan control module connector.
2. Turn the ignition switch to the "ON" position, and measure the voltage
between the harness-side connector terminals.
Standard value: Battery positive voltage
CAUTION: Do not overfill the radiator condenser tank
assembly.
