Customer Concern Verification Sheets

The GM Customer Concern Verification Sheets have been designed to improve communications between the service customer and the technician. The more clearly the technician understands the concern and its symptoms, the more likely the concern will be fixed right the first time.

The GM-wide Customer Concern Verification Sheets are available in DealerWorld. The Customer Concern Verification Sheets may be printed and reproduced locally.

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 4

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

1. Lower strength
2. No numbered head marking system
3. 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

1. M6.0 X 1
2. M8 X 1.25
3. M10 X 1.5
4. M12 X 1.75
5. M14 X 2.00
6. M16 X 2.00

Adhesive Coated Fasteners

These fasteners accomplish the thread interface by the presence of a thread-locking compound on the fastener threads. Refer to the appropriate repair procedure in order to determine if the fastener may be reused and the applicable thread-locking compound to apply to the fastener.

Scheme 5

A prevailing torque fastener may be reused ONLY if

1. The fastener and the fastener counterpart are clean and not damaged
2. There is no rust on the fastener
3. The fastener develops the specified minimum torque against its counterpart prior to the fastener seating

Thread Inserts

General Purpose Thread Repair Kits.

These kits are available commercially.

Repair Procedure

1. 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.
2. Drill out the damaged threads. Clean out any chips.
3. Lubricate the tap with light engine oil. Tap the hole. Clean the threads.
4. Thread the thread insert onto the mandrel of the installer. Engage the tang of the insert onto the end of the mandrel.
5. Lubricate the insert with light engine oil, except when installing in aluminum and install the insert.
6. If the tang of the insert does not break off when backing out the installer, break the tang off with a drift.

Registered and Non-Registered Trademarks

Listed below are Registered Trademarks (®) or Non-Registered Trademarks (™) which may appear in this service manual.

Ignition Lock Cylinder

The ignition lock cylinder uses only 7 of the 10 cut positions, 2 through 8. The ignition cylinder tumblers (3) are located on alternate sides of the cylinder (1). They are snap-in and self-retaining. It follows the key code with the first tumbler being the first depth of the key code, closest to the head of the key.

1. Hold the ignition cylinder assembly (1) so the side with the tumbler spring pocket located closest to the head of the cylinder is facing up.
2. Insert the tumbler spring (2) into each of the 4 spring pockets of the cylinder assembly.
3. The first tumbler (3) to be loaded will be the second key cut position, which is the second number in the key code. Install the first tumbler in the slot over the spring. Install the remaining tumblers for cuts 4, 6, and 8 following the key code and same process, pressing the tumblers in place until they are secure.
4. Rotate the cylinder assembly. Insert the tumbler spring into each of the spring pockets of the cylinder assembly.
5. The first tumbler to be loaded will be the third key cut position, the third number in the key code. Install the first tumbler in the slot over the spring. Install the remaining tumblers for cuts 5 and 7 following the key code and same process, pressing the tumblers in place until they are secure.
6. Inspect for correct loading of the tumblers by inserting the key into the cylinder. All tumblers should drop flush with the lock cylinder body diameter.
7. Lightly lubricate the outside surface in the tumbler area of the lock body and down the key slot using the provided grease. Insert and extract the key 5 times to lubricate the keyway.
8. With the key in the cylinder assembly, insert the actuator (4) in the actuator pocket and hold. Rotate the cylinder assembly and insert the retainer spring (6) in the retainer slot located in the cylinder assembly. Insert the retainer (7) lining it up in the slot over the spring. Depress the retainer and hold.
9. Insert the cylinder into the sleeve (5) as shown in the print. Make sure the actuator stays located properly in the cylinder.
10. When the key is removed, the lock should stay together.
11. Insert the key and function the lock 3 times to distribute the grease inside the sleeve.
12. Verify the key position for inserting the lock into the column.

Door Lock Cylinder

The door lock cylinder only uses 7 of the 10 cut positions, 4 through 10. The tumbler positions are staggered from side to side, 4 on one side and 3 on the other are self-retaining. The left and right door lock cylinders are identical. The lever assembly determines which side of the vehicle the lock cylinder is for. After removing the current lock, record which lever is used and the orientation of the rod clip.

1. Rotate the cylinder (1) so the side with the 4 tumblers spring wells faces up.
2. Insert the tumblers springs (2) into the 4 spring wells.
3. Install the tumbler (3) for key cut position 4 in the slot closest to the cylinder head. Install the remaining tumblers, key cut positions 6, 8, 10, following the key code and same process. Press tumblers in place until they are secure.
4. Check the correct loading of the tumblers by inserting the key into the cylinder. All tumblers should be flush with the lock cylinder body.
5. Turn the cylinder so the side with the 3 tumblers spring wells faces up.
6. Insert the tumbler springs into the 3 spring wells.
7. The first tumbler closest to the front of the lock cylinder to be loaded will be the fifth key cut position. Install the remaining tumblers for the key cut positions 7 and 9. Press tumblers in place until they are secure.
8. Check the correct loading of the tumblers by inserting the key into cylinder. All of the tumblers should be flush with the lock cylinder body.
9. Apply lubricant to cylinder body and tumbler surfaces along with a small amount in head of cylinder using the supplied grease.
10. Install 2 springs (4) into the spring wells in head section of lock cylinder.
11. Snap the shutter assembly (5) into the cylinder.
12. Place the detent spring (6) into the spring well located on side of cylinder.
13. Carefully place the detent ball (7) on detent spring. Depress the detent ball into the cylinder and assemble into case (8). Detent ball should rest in case slot at front of case.
14. Align dimples of the cylinder cap (9) with the 4 recesses in the cap. Secure by pressing the cap into place with light hand pressure.
15. If required, assemble rod clip to lever (10) using the recorded lever information.
16. Assemble lever to lock. Use e-clip (11) to retain lever assembly.
17. Insert the key into the lock and function lock to check for proper assembly and smooth operation.
