2004 MITSUBISHI ENDEAVOR check engine

1. Check that the coolant level is up to the filler neck. Install a radiator tester and
apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator
hose or connections.
burned by hot coolant.
CAUTION:
Be sure to completely clean away any moisture
from the places checked. When the tester is taken out, be careful not to
spill any coolant. Be careful when installing and removing the
tester and when testing not to deform the filler
neck of the radiator.

2. If there is leakage, repair or replace the appropriate part.
RADIATOR CAP PRESSURE CHECK 1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the gauge stops moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93 - 123 kPa (14 - 18 psi)

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.

6. Turn the A/C switch to the "ON" position.
7. Measure the voltage between the fan control module-side connector terminals
while the fan is running. The voltage should repeat the values 1) and 2) below.
Standard value:
1.8.2+/-2.6 V
2.Battery positive voltage+/-2.6 V
8. If the voltage does not repeatedly change as indicated, replace the radiator fan
motor.

2. Check that the amount of valve lift is at the standard value when the water is at
the full-opening temperature.
Standard value:
Full-opening temperature:100°C (212°F)
Amount of valve lift: 9.0 mm (0.35 inch) or more
NOTE: Measure the valve height when the thermostat is fully
closed, and use this measurement to compare the valve
height when the thermostat is fully open.
