Toyota Corolla Repair Manual: Inspection

1. Thermostat

Hint:

Hint

: the thermostat is numbered with the valve opening temperature.

  1. Immerse the thermostat in water and gradually heat the water.
  2.  check the valve opening temperature.

    Valve opening temperature: 80 to 84 c (176 to 183 f)

Hint

: if the valve opening temperature is not as specified, replace the thermostat.

  1. Check the valve lift.

    Valve lift: 10 mm (0.39 In.) Or more at 95 c (203 f)

Hint

: if the valve lift is not as specified, replace the thermostat.

  1.  check that the valve is fully closed when the thermostat is at low temperatures (below 77 c (171 f)).

Hint: if not closed, replace the thermostat.

2. Radiator cap subassy

Notice

:

  1. Using a radiator cap tester, slowly pump the tester and check that air is coming from the vacuum valve.

    Pump speed: 1 push / 3 seconds or more

Notice

: push the pump at a constant speed. If air is not coming from the vacuum valve, replace the radiator cap.

  1.  pump the tester and measure the relief valve opening pressure.

    Pump speed: 1 push within 1 second

Notice: the above pump speed is for the first pump only (in order to close the vacuum valve). After the first pump, the pump speed can be reduced. Standard opening pressure: 74 to 103 kpa (0.75 To 1.05 Kgf/cm2, 10.7 To 14.9 Psi) minimum opening pressure: 59 kpa (0.6 Kgf/cm2, 8.5 Psi)

Hint

: use the testers maximum reading as the opening pressure.

If the opening pressure is less than minimum, replace the radiator cap.

Circuit description
When the idle switch is turned on, a signal is sent to the cruise control ecu assy. The cruise control ecu assy uses this signal to correct the discrepancy between the throttle valve position and the actuator position sensor values to enable accurate cruise control at the set speed. If the idl ...
