Oil Leakage Inspection

Using UV light (black light)

1.Remove any oil on the engine or transaxle/transmission.

Note

• Referring to the fluorescent dye instruction manual, mix the specified amount of dye into the engine oil or ATF (or transaxle/transmission oil).

2.Pour the fluorescent dye into the engine oil or ATF (or transaxle/transmission oil).

3.Allow the engine to run for 30 min.

4.Inspect for dye leakage by irradiating with UV light (black light), and identify the type of oil that is leaking.

5.If no dye leakage is found, allow the engine to run for another 30 min. or drive the vehicle then reinspect.

6.Find where the oil is leaking from, then make necessary repairs.

Note

• To determine whether it is necessary to replace the oil after adding the fluorescent dye, refer to the fluorescent dye instruction manual.

Not using UV light (black light)

1.Gather some of the leaking oil using an absorbent white tissue.

2.Take samples of engine oil and ATF (or transaxle/transmission oil), both from the dipstick, and place them next to the leaked oil already gathered on the tissue.

3.Compare the appearance and smell, and identify the type of oil that is leaking.

4.Remove any oil on the engine or transaxle/transmission.

5.Allow the engine to run for 30 min.

6.Check the area where the oil is leaking, then make necessary repairs.

Removal of Parts

• While correcting a problem, also try to determine its cause. Begin work only after first learning which parts and subassemblies must be removed and disassembled for replacement or repair. After removing the part, plug all holes and ports to prevent foreign material from entering.

am3uuw00001923

Disassembly

• If the disassembly procedure is complex, requiring many parts to be disassembled, all parts should be marked in a place that will not affect their performance or external appearance and identified so that reassembly can be performed easily and efficiently.

am3uuw00001924

Inspection During Removal, Disassembly

• When removed, each part should be carefully inspected for malfunction, deformation, damage and other problems.

am3uuw00001925

Arrangement of Parts

• All disassembled parts should be carefully arranged for reassembly.

am3uuw00001926

Cleaning of Parts

• All parts to be reused should be carefully and thoroughly cleaned in the appropriate method.

am3uuw00001927

Warning

• Using compressed air can cause dirt and other particles to fly out causing injury to the eyes. Wear protective eye wear whenever using compressed air.

Reassembly

• Standard values, such as torques and certain adjustments, must be strictly observed in the reassembly of all parts.

― Oil seals

― Gaskets

― O‐rings

― Lock washers

― Cotter pins

― Nylon nuts

• Depending on location:

amxzzw00000063

― Sealant and gaskets, or both, should be applied to specified locations. When sealant is applied, parts should be installed before sealant hardens to prevent leakage.

― Oil should be applied to the moving components of parts.

― Specified oil or grease should be applied at the prescribed locations (such as oil seals) before reassembly.

Adjustment

• Use suitable gauges and testers when making adjustments.

Rubber Parts and Tubing

• Prevent gasoline or oil from getting on rubber parts or tubing.

am3uuw00001931

Hose Clamps

• When reinstalling, position the hose clamp in the original location on the hose and squeeze the clamp lightly with large pliers to ensure a good fit.

am3uuw00001932

Torque Formulas

• When using a torque wrench‐ SST or equivalent combination, the written torque must be recalculated due to the extra length that the SST or equivalent adds to the torque wrench. Recalculate the torque by using the following formulas. Choose the formula that applies to you.

am3uuw00001938

Vise

• When using a vise, put protective plates in the jaws of the vise to prevent damage to parts.

am3uuw00001940

Dynamometer

― Place a fan, preferably a vehicle‐speed proportional type, in front of the vehicle.

― Make sure the vehicle is in a facility with an exhaust gas ventilation system.

― Since the rear bumper might deform from the heat, cool the rear with a fan. (Surface of the bumper must be below 70 °C {158 °F}.)

― Keep the area around the vehicle uncluttered so that heat does not build up.

― Watch the water temperature gauge and don’t overheat the engine.

― Avoid added load to the engine and maintain normal driving conditions as much as possible.

Note

• When only the front or rear wheels are rotated on a chassis dynamometer or equivalent, the DSC HU/CM determines that there is a malfunction in the DSC and illuminates the following lights:

― ABS warning light

― Brake system warning light

― DSC indicator light

• If the above lights are illuminated, dismount the vehicle from the chassis dynamometer and switch the ignition to LOCK position. Then, switch the ignition to ON position, run the vehicle at 10 km/h or more and verify that the warning lights go out. In this case, a DTC will be stored in the memory. Clear the DTC from the memory by following the memory clearing procedure [DSC] in the on-board diagnostic system. (See ON-BOARD DIAGNOSIS.)
