General Information: Other Mazda 3 BM

Range of Topics

1. This manual contains procedures for performing all required service operations. The procedures are divided into the following five basic operations: Removal/Installation Disassembly/Assembly Replacement Inspection Adjustment
2. Simple operations which can be performed easily just by looking at the vehicle (i.e., removal/installation of parts, jacking, vehicle lifting, cleaning of parts, and visual inspection) have been omitted.

Scheme 31

1. Inspection and adjustment procedures are divided into steps. Important points regarding the location and contents of the procedures are explained in detail and shown in the illustrations.

Scheme 32

1. Most repair operations begin with an overview illustration. It identifies the components, shows how the parts fit together, and describes visual part inspection. However, only removal/installation procedures that need to be performed methodically have written instructions.
2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview illustration. In addition, symbols indicating parts requiring the use of special service tools or equivalent are also shown.
3. Procedure steps are numbered and the part that is the main point of that procedure is shown in the illustration with the corresponding number. Occasionally, there are important points or additional information concerning a procedure. Refer to this information when servicing the related part.

Symbols

1. There are eight symbols indicating oil, grease, fluids, sealant, and the use of SST or equivalent. These symbols show application points or use of these materials during service.

Scheme 33

Advisory Messages

1. You will find several Warnings, Cautions, Notes, Specifications and Upper and Lower Limits in this manual.

Warning

1. A Warning indicates a situation in which serious injury or death could result if the warning is ignored.

Caution

1. A Caution indicates a situation in which damage to the vehicle or parts could result if the caution is ignored.

Note

1. A Note provides added information that will help you to complete a particular procedure.

Upper and lower limits

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

Scheme 34

UNITS

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.

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
2. 210-260 kPa {2.1-2.7 kgf/cm 2 , 30-38 psi}
3. 270-310 kPa {2.7-3.2 kgf/cm 2 , 39-45 psi}
4. 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 is switched to 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.

Scheme 35

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

Scheme 36

1. Be sure that all necessary tools and measuring equipment are available before starting any work.

Scheme 37

1. Use special service tools or equivalent when they are required.

1. Before removing the SRS air bag system-related parts, always disconnect the negative battery cable and wait for 1 min. or more to allow the back-up power supply to deplete its stored power.

Using UV light (black light)

1. 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.
2. Pour the fluorescent dye into the engine oil or transmission/transaxle 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.

Scheme 38

1. Gather sample of the leaking oil using an absorbent white tissue.
2. 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
3. Compare the appearance and smell, and identify the type of oil that is leaking.
4. Remove any oil on the engine or transmission/transaxle.
5. Allow the engine to run for 30 min.
6. Check the area where the oil is leaking, then make necessary repairs.

Scheme 40

Dynamometer

1. When inspecting and servicing the power train on the dynamometer or speed meter 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 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 ABS/DSC HU/CM determines that there is a malfunction in the ABS and illuminates the following lights: Vehicles with ABS ABS warning light Brake system warning light Vehicles with DSC 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. 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 [ABS]/[DSC] in the on-board diagnostic system. (See ON-BOARD DIAGNOSIS [ABS] .)(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)

SST

1. Some global SST or equivalent are used as SSTs necessary for engine repair. Note that these SSTs are marked with global SST numbers.
2. Note that a global SST number is written together with a corresponding Mazda SST number as shown below.
