9000 L4-1985cc 2.0L DOHC (1986)
1.
Interview the customer to determine what type of noise is being heard, when it is heard, and the operating conditions under which the customer
drives the vehicle.
2.
Check the ATF level to ensure that it is correct. Review the service history to determine when the ATF was last changed.
3.
Verify the complaint by test driving the car until the transmission is warm.
4.
Unbolt the ATF thermostatic valve from the engine subframe attachment bolt. Suspend the valve using tie straps so it will be isolated from the
subframe.
5.
Test drive the car again. If the noise is eliminated or greatly reduced, proceed with the repair procedure. If the noise level is not changed, perform
further diagnosis to determine the source of the noise.
Figure 1.
Repair Procedure
1.
Remove the battery and tray.
2.
Clean the ATF hose fittings at Positions A and B (Figure 1). Remove the banjo bolts and seal rings. Let the loose hoses hang in front of
transmission.
CAUTION
When loosening the banjo bolts at the waterto-oil and air-to-oll coolers, use a wrench on the cooler fittings to oppose the torque exerted on the
banjo bolts. Failure to do so may cause damage to the coolers, resulting in ATF and/or antifreeze leakage.
3.
Clean the upper hose fitting at Position C (Figure 1) for the water-to-oil cooler mounted within the radiator tank. Remove the banjo bolt and seal
rings.
4.
Raise the car and set the lift.
5.
Remove the center panel behind the front spoiler.
6.
Clean the hose fitting at Position D (Figure 1). Remove the banjo bolt and seal rings.
7.
Loosen the nut used to secure the supply hose to the radiator air-to-oil cooler bracket (Position E, Figure 1).
8.
Remove the nut securing the thermostatic valve to the engine subframe. Remove the valve together with the hoses and refit the nut. Torque the nut
to 50 N-m (37 ft.lb.).
