CVT FLUID COOLER SYSTEM

b. If one or more pieces of debris are found that are over 1 mm

(0.040 in) in size and/or peeled clutch facing material is found in

the coffee filter, the fluid cooler is not serviceable. The radiator/

fluid cooler must be replaced and the inspection procedure is

ended.

CVT FLUID COOLER FINAL INSPECTION

After performing all procedures, ensure that all remaining oil is cleaned from all components.

INSPECTION

1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the

CVT fluid temperature is 50 to 80

°C (122 to 176°F). Inspect the

amount of CVT fluid. Replenish if necessary.

3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.

• It is good practice to mark the point of specified engine

rpm on indicator.

5. Start engine, apply foot brake, and place selector lever in “D”

position.

6. While holding down the foot brake, gradually press down the

accelerator pedal.

7. Quickly read off the stall speed, and then quickly remove your

foot from the accelerator pedal.

CAUTION:

Do not hold down the accelerator pedal for more than 5 sec-

onds during this test.

8. Move the selector lever to the “N” position.
9. Cool down the CVT fluid.

CAUTION:

Run the engine at idle for at least 1 minute.

10. Repeat steps 6 through 9 with selector lever in “R” position.

INSPECTION

Line Pressure Test Port (A)

Line Pressure Test Procedure

1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80

°C

(122 to 176

°F), then inspect the amount of CVT fluid and replenish if necessary.

NOTE:

The CVT fluid temperature rises in the range of 50 to 80

°C (122 to 176°F) during 10 minutes of driving.

3. After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge [special

service tool: — (OTC3492)].

CAUTION:

When using the oil pressure gauge, be sure to use the O-ring attached to the oil pressure detec-

tion plug.

4. Securely engage the parking brake so that the tires do not turn.

5. Start the engine, and then measure the line pressure at both idle

and the stall speed.

CAUTION:

• Keep the brake pedal pressed all the way down during

measurement.

• When measuring the line pressure at the stall speed.

Refer to 

TM-451, "Stall Speed"

. 

6. After the measurements are complete, install the oil pressure

detection plug and tighten to the specified torque below.

CAUTION:

• Do not reuse O-ring.

• Apply CVT fluid to O-ring.
