REFER TO THE SRS COMPONENT AND WIRING LOCATION VIEW IN ORDER TO DETERMINE WHETHER YOU ARE PERFORMING SERVICE ON OR NEAR THE SRS COMPONENTS OR THE SRS WIRING. WHEN YOU ARE PERFORMING SERVICE ON OR NEAR THE SRS COMPONENTS OR THE SRS WIRING, REFER TO THE SRS SERVICE INFORMATION. FAILURE TO FOLLOW WARNINGS COULD RESULT IN POSSIBLE AIR BAG DEPLOYMENT, PERSONAL INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.CAUTION: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. ISUZU will call out those fasteners that require a replacement after removal. ISUZU will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (Paints, greases, or other corrosion inhibitors) on threaded fasteners or fasteners joint interfaces. Generally, such coatings adversely affect the fastener torque and the joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specification. Following these instructions can help you avoid damage to parts and systems.
  16. 16. 0A2 GENERAL INFORMATIONGENERAL REPAIR INSTRUCTIONS 1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle. 2. Use covers on the vehicle body, seats, and floor to prevent damage and/or contaminations. 3. Disconnect the grounding cable from the battery before performing service operations. This will prevent cable damage or burning due to shortcircuiting. 4. Raise the vehicle with a jack set against the recommended lifting points (see Lifting instructions in this section). 5. Support the vehicle on chassis stands. 6. Handle brake fluid and antifreeze solution with great care. Spilling these liquids on painted surfaces will damage the paint. 7. The use of the proper tool(s) and special tool(s) where specified is essential to efficient, reliable, and safe service operations. 8. Always use genuine ISUZU replacement parts. 9. Discard used cotter pins, gasket, plastic clips, O-rings, oil seals, lock washers, and selflocking nuts at disassembly. Normal function of these parts cannot be guaranteed if they are reused. 10. Keep the disassembled parts neatly in groups. This will facilitate smooth and correct reassembly.11. Keep fixing nuts and bolts separate. Fixing nuts and bolts vary in hardness and design according to installation positions. 12. Clean all parts before inspection or reassembly. 13. Clean the oil ports and other openings with compressed air to make certain that they are free of dirt and obstructions. 14. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation. 15. Use the recommended liquid gasket to prevent leakage. 16. Carefully observe all nut and bolt torque specifications. 17. When service operation is completed, make a final check to be sure service has been done properly and problem has been corrected. 18. When removing or replacing parts that require refrigerant to be discharged from the air conditioning system, be sure to use the following tools to recover and recycle the Refrigerant-134a (R-134a). For 134a: Use the R-134a Refrigerant Recovery/Recovery/ Recycling/Recharging/System (ACR4) or its equivalent to prevent the discharge of refrigerant into the air.

In Service Information, an opening section of each manual, the troubleshooting, maintenance servicing, service data and/or information on special tools required for the service operations described in the next subsequent sections are arranged and compiled so concisely that you can see at a first glance. 3. Each section except the Service Information section is basically arranged in the following order of headings: General description On-vehicle service Unit repair4. The service operations are in two groups: one is the On-vehicle service where operations can be directly performed on the vehicle, and the other is the Unit repair where the operations are done on the work bench after removing the unit from the vehicle. 5. Each service operation section begins with a disassembled view of unit or equipment, which is useful to find relative components, service procedure, availability and contents of repair kits, etc.The number represents sequence of removal or disassembly Removal of unnumbered the parts (excluding bolts, nuts, washers, gaskets, cotter pins, etc.) is unnecessary unless replacement is needed. Where parts replacement requires specific information, instructions are given in Inspection and Repair. This frame is to be removed as a large disassembly with all the parts assembled in the frame. Each one of the parts in the frame is removed as a small disassembly. Parts to be removed or installed as a unit. 5 Parts contained in repair kit. 5 Indicates repair kit availability. When the installation (reassembly) procedure is the reverse order of the removal (disassembly) procedure, the sequence of service operation and the parts names will be omitted. Name of parts listed in sequence of service operation.

However, even when the air conditioning is in oper-ation, the electronic thermostat, the pressure switch or the PCM (6VD1/6VE1 Engine) is used to stop the air conditioning temporarily by turning off the magnetic clutch in the prearranged conditions to reduce the engine load which is being caused by the rise in the engine coolant temperature, and the acceleration of the vehicle, etc.6VD1/6VE1 ENGINE Pin number with ( BATTERYRELAY; A/C B-36FL-1 80A MAIN); RHDC-25C-20 10A A/C1 PRESSURE SW. 22 2 4 6 1RELAY; THERMOSTAT(3) 1 (1) 3A/C SW.X-5I-23C-3PCM (E15)42 4FAN SW.3RELAY: A/C COMPRESSOR4121OFF 13I-18 B-1 (RHD)X-7B-2C-1(LHD)PCM (B14)31MgMAGNETIC CLUTCH1ELECTRONIC THERMOSTATE-3 2I-42B-1B-2I-42B-36X-5X-711 2 323C-25411 234 23 2 1 W/ CONDENSER FANE-3I-181 4112 5C-1I-233 61 42 5C-3A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13 B14 B15 B16E1 E2 E3 E4 E5 E6 E7 E8 E9 E10 E11 E12 E13 E14 E15 E16 F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14 F15 F163 6D08RY00295

They have been prepared in order of accessibility of the components. When a compressor is removed from the vehicle for servicing, the amount of PAG lubricant remaining in the compressor should be drained, measured and recorded. This PAG lubricant should then be discarded and an equal amount of new PAG lubricant added to the compressor. The service compressor is shipped without PAG oil. When service procedures require, use only Isuzu approved PAG oil.
