Upper and lower limits

1. The values indicate the upper and lower limits that must not be exceeded when performing inspections or adjustments.

Scheme 23

UNITS

UNITS CHART

Conversion to SI Units (Systeme International d'Unites)

1. All numerical values in this manual are based on SI units. Numbers shown in conventional units are converted from these values.

Rounding Off

1. Converted values are rounded off to the same number of places as the SI unit value. For example, if the SI unit value is 17.2 and the value after conversion is 37.84, the converted value will be rounded off to 37.8.

Upper and Lower Limits

1. When the data indicates upper and lower limits, the converted values are rounded down if the SI unit value is an upper limit and rounded up if the SI unit value is a lower limit. Therefore, converted values for the same SI unit value may differ after conversion. For example, consider 2.7 kgf/cm 2 in the following specifications: 210-260 kPa {2.1-2.7 kgf/cm 2 , 30-38 psi} 270-310 kPa {2.7-3.2 kgf/cm 2 , 39-45 psi}
2. The actual converted values for 2.7 kgf/cm 2 are 264 kPa and 38.4 psi. In the first specification, 2.7 is used as an upper limit, so the converted values are rounded down to 260 and 38. In the second specification, 2.7 is used as a lower limit, so the converted values are rounded up to 270 and 39.

Injury/damage Prevention Precautions

1. Depending on the vehicle, the cooling fan may operate suddenly even when the ignition switch is turned off. Therefore, keep hands and tools away from the cooling fan even if the cooling fan is not operating to prevent injury to personnel or damage to the cooling fan. Always disconnect the negative battery cable when servicing the cooling fan or parts near the cooling fan.

Protection of the Vehicle

1. Always be sure to cover fenders, seats and floor areas before starting work.

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 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.

Scheme 27

Arrangement of Parts

1. All disassembled parts should be carefully arranged for reassembly.
2. Be sure to separate or otherwise identify the parts to be replaced from those that will be reused.

Scheme 28

Cleaning of Parts

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

Scheme 29

Scheme 30

Scheme 31

1. Standard values, such as torques and certain adjustments, must be strictly observed in the reassembly of all parts.
2. If removed, these parts should be replaced with new ones: Oil seals Gaskets O-rings Lock washers Cotter pins Nylon nuts
3. 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.

Rubber Parts and Tubing

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

Scheme 32

Hose Clamps

1. 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 33

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

Scheme 34

Dynamometer

1. When inspecting and servicing the power train on the dynamometer or speedometer tester, pay attention to the following: 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 do not 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 turn the ignition switch to the LOCK position. Then, turn the ignition switch back to the 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 onboard diagnostic system. (See «ON-BOARD DIAGNOSIS»(ref-375322-S24289626392010102800000) .)

Speedometer tester measurement
