| Anti-Theft Label | |
| 20 | The Federal law requires that General Motors label certain body parts on this vehicle with the VIN. The purpose of the law is to reduce the number of motor vehicle thefts by helping in the tracing and recovery of parts from stolen vehicles. Labels are permanently affixed to an interior surface of the part. The label on the replacement part contains the letter R, the manufacturer's logo and the DOT symbol. The anti-theft label must be covered before any painting and rustproofing procedures and uncovered after the procedures. Failure to follow the precautionary steps may result in liability for violation of the Federal Vehicle Theft Prevention Standard and possible suspicion to the owner that the part was stolen. |

Metric Fasteners
This vehicle provides fastener dimensions using the metric system. Most metric fasteners are approximate in diameter to equivalent English fasteners. Make replacements using fasteners of the same nominal diameter, thread pitch and strength.
A number marking identifies the OE metric fasteners except cross-recess head screws. The number also indicates the strength of the fastener material. A Posidrive® or Type 1A cross-recess identifies a metric cross-recess screw. For best results, use a Type 1A cross-recess screwdriver or equivalent, in Posidrive® recess head screws.
GM Engineering Standards and North American Industries have adopted a portion of the ISO-defined standard metric fastener sizes. The purpose was to reduce the number of fastener sizes used while retaining the best thread qualities in each thread size. For example, the metric M6.0 X 1 screw, with nearly the same diameter and 25.4 threads per inch replaced the English 1/4-20 and 1/4-28 screws. The thread pitch is midway between the English coarse and fine thread pitches.
Scheme 5
| Callout | Component Name |
|---|---|
| 1 | English Bolt, Grade 2 (Strength Class) |
| 2 | English Bolt, Grade 5 (Strength Class) |
| 3 | English Bolt, Grade 7 (Strength Class) |
| 4 | English Bolt, Grade 8 (Strength Class) |
| 5 | Metric Nut, Strength Class 9 |
| 6 | Metric Bolts, Strength Class Increases as Numbers Increase |
The most commonly used metric fastener strength property classes are 9.8 and 10.9. The class identification is embossed on the head of each bolt. The English, inch strength classes range from grade 2 to grade 8. Radial lines are embossed on the head of each bolt in order to identify the strength class. The number of lines on the head of the bolt is 2 lines less than the actual grade. For example, a grade 8 bolt will have 6 radial lines on the bolt head. Some metric nuts are marked with a single digit strength identification number on the nut face.
The correct fasteners are available through GM SPO. Many metric fasteners available in the aftermarket parts channels are designed to metric standards of countries other than the United States and may exhibit the following
- Lower strength
- No numbered head marking system
- Wrong thread pitch
The metric fasteners on GM products are designed to new, international standards. The following are the common sizes and pitches, except for special applications
- M6.0 X 1
- M8 X 1.25
- M10 X 1.5
- M12 X 1.75
- M14 X 2.00
- M16 X 2.00
Thread Inserts
General Purpose Thread Repair Kits.
These kits are available commercially.
Repair Procedure
- Determine the size, the pitch and the depth of the damaged thread. If necessary, adjust the stop collars on the cutting tool and tap to the required depth.
- Drill out the damaged threads. Clean out any chips.
- Lubricate the tap with light engine oil. Tap the hole. Clean the threads.
- Thread the thread insert onto the mandrel of the installer. Engage the tang of the insert onto the end of the mandrel.
- Lubricate the insert with light engine oil, except when installing in aluminum and install the insert.
- If the tang of the insert does not break off when backing out the installer, break the tang off with a drift.

Lifting and Jacking the Vehicle
| WARNING | To avoid any vehicle damage, serious personal injury or death, always use the jackstands to support the vehicle when lifting the vehicle with a jack. |
| WARNING | To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the vehicle to the hoist. |
| CAUTION | Perform the following steps before beginning any vehicle lifting or jacking procedure: Remove or secure all of the vehicle contents in order to avoid any shifting or any movement that may occur during the vehicle lifting or jacking procedure. The lifting equipment or the jacking equipment weight rating must meet or exceed the weight of the vehicle and any vehicle contents. The lifting equipment or the jacking equipment must meet the operational standards of the lifting equipment or jacking equipment manufacturer. Perform the vehicle lifting or jacking procedure on a clean, hard, dry, level surface. Perform the vehicle lifting or jacking procedure only at the identified lift points. DO NOT allow the lifting equipment or jacking equipment to contact any other vehicle components. Failure to perform the previous steps could result in damage to the lifting equipment or the jacking equipment, the vehicle, and/or the vehicle contents. |
For lifting the vehicle, various lift points are recommended. Before you begin any lifting procedure, place the vehicle on a clean, hard, level surface. Verify that all the lifting equipment meets weight standards and is in good working order. Verify that all of the vehicle loads are equally distributed and secure. If you are only supporting the vehicle at the frame side rails, verify that the lifting equipment does not put too much stress on or weaken, the frame side rails.
During hoisting, do NOT damage the fuel tanks, the exhaust system or the underbody.
