Using UV light (black light)
- Remove any oil on the engine or transmission/transaxle. NOTE: Referring to the fluorescent dye instruction manual, mix the specified amount of dye into the engine oil or transmission/transaxle oil.
- Pour the fluorescent dye into the engine oil or transmission/transaxle oil.
- Allow the engine to run for 30 min.
- Inspect for dye leakage by irradiating with UV light (black light), and identify the type of oil that is leaking.
- If no dye leakage is found, allow the engine to run for another 30 min. or drive the vehicle then reinspect.
- 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.
Scheme 29
Scheme 29: Not using UV light (black light)
- Gather sample of the leaking oil using an absorbent white tissue.
- Then gather some samples of engine and transmission/transaxle oil onto a white cloth or piece of paper. MT vehicles: Transmission/transaxle oil AT vehicles: ATF
- Compare the appearance and smell, and identify the type of oil that is leaking.
- Remove any oil on the engine or transaxle/transmission.
- Allow the engine to run for 30 min.
- Check the area where the oil is leaking, then make necessary repairs.

Scheme 30: Removal of Parts
- While correcting a problem, also try to determine its cause. Begin work only after first learning which parts and sub-components must be removed and disassembled for replacement or repair. After removing the part, plug all holes and ports to prevent foreign material from entering.
Scheme 31
- 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.
Scheme 32
Scheme 32: Inspection During Removal, Disassembly
- When removed, each part should be carefully inspected for malfunction, deformation, damage and other problems.
Scheme 33
Scheme 33: Arrangement of Parts
- All disassembled parts should be carefully arranged for reassembly.
- Be sure to separate or otherwise identify the parts to be replaced from those that will be reused.
Scheme 34
Scheme 34: Cleaning of Parts
- All parts to be reused should be carefully and thoroughly cleaned in the appropriate method. 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.
Scheme 35
Scheme 36
- Standard values, such as torques and certain adjustments, must be strictly observed in the reassembly of all parts.
- If removed, these parts should be replaced with new ones: Oil seals Gaskets O-rings Lock washers Cotter pins Nylon nuts
- Depending on location: 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.
Scheme 37
- Use suitable gauges and testers when making adjustments.
Scheme 38
Scheme 38: Rubber Parts and Tubing
- Prevent gasoline or oil from getting on rubber parts or tubing.
Scheme 39
- 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.
Scheme 40
Scheme 40: Torque Formulas
- When using a torque wrench- SST or equivalent combination, the specified 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. TORQUE FORMULAS Torque Unit Formula N.m N.m x [L/(L+A)] kgf.m kgf.m x [L/(L+A)] kgf.cm kgf.cm x [L/(L+A)] ft.lbf ft.lbf x [L/(L+A)] in.lbf in.lbf x [L/(L+A)] A : The length of the SST past the torque wrench drive. L : The length of the torque wrench.
Scheme 41
- When using a vise, put protective plates in the jaws of the vise to prevent damage to parts.
