0’5 Vehicle identification numbers Vehicle identification numbers Modifications are a continuing and uftpublicized process in vehicle manufactur ing. Since spare parts manuals and lists are compiled on a numerical basis, the individual vehicle numbers are necessary to correctly identify the component required. Vehicle Identification Number (VIN) Thfs very important identification number is located on a plate attached to the left side dashboard just inside the windshield {see ^lustration). The VIN also appears on the Vehicle Certificate of Title and Registration. It contains information such as where and when the vehicle was manufactured, engine type, the model year and the body style. Vehicle Certification Label The Vehicle Certification label (VC label, also referred to as the Truck Safety Compli- ance Certification label) is attached lo the front of the left (driver's side) door pillar (see Illustration). The upper half of (he label con tains the name of the manufacturer, the month and year of production, the Gross Vehicle Weight Rating (GVWFt), the Gross We'9h1 Rating (GAWR) and the certifies- tion statement, 1 he VC label also contains the VIN num ber, which is used for warranly identification of the vehicle, and provides such information as manufacturer, type of restraint system, body type, engine, transmission, model year and vehicle serial number. Engine numbers Labels containing the engine code, cali bration and serial numbers, as well as plant name, can be found on the valve cover, as well as stamped on the engine itself (see illustration). The engine code is also found as the eighth digit of the VIN code. The letter X indicates the 4,QL pushrod V 6, the letter E indicates the -VOL SOHC VS. and the letter P indicates the 5,0L VS. On 2001 and later models, the letter К indicates the "Flexible fuel" version of (he 4,QL SOHC V 6 engine. Manual transmission numbers The manual transmission identification number and serial numbers can be found on a tag on Ihe left or right side of the transmis sion main case. Automatic transmission numbers Tags with the automatic transmission serial number, build date and other informa tion are attached with a bolt, usually at the extension housing. Vehicle Emissions Control Information (VECI) label This label is found under the hood [see Chapter 6 ).

Fasteners Fasteners are nuts, bolts, studs and screws used to hold two or more parts together. There are a few things to keep in mind wtien worthing with fasteners. Almost all of them use a locking device of some type, either a lockwasher, iocknut. locking tab or thread adhesive. All threaded fasteners should be dean and straight, with undam aged threads and undamaged corners on the hex head where the wrench fits. Deveiop the habit of replacing all damaged nuts and bolts with new ones. Special locknuts with nylon or liber inserts can only be used once. If they are removed, they lose their locking ability and must be replaced with new ones. Rusted nuts and bolts should be treated w th a penetrating fluid to ease removal and “ ^ r®aka9e.

Never use a lockwasher on any soft metal surface (such as aluminum), thin sheet metal or plastic.

Therefore, it is impor tant to be able to tall the difference between standard {sometimes called U,S. or SAE) and melric hardware, since they cannot be inter changed. All bolts, whether standard or metric, are sized according to diameter, thread pitch and length, For example, a standard 1 / 2 - 1 3 x 1 boft is 1/2 inch in diameter, has 13 threads per inch and is 1 fnch long. An M l2 - 1.75 x 25 metric bolt is 12 mm in diameter, has a thread pitch of 1,75 mm (the distance between threads) and is 25 mm fang. The two bolts are nearly identical, and easily confused, but they are not interchangeable. In addition to the differences in diame ter, thread pitch and length, me trie and stan dard bolts can also be distinguished by examining the bolt heads. To begin with, the distance across the flats on a standard bolt head is measured in fnches, while the same dimension on a metric boit rs sized in millime ters [the same is true for nuts). As a result, a standard wrench should not be used on a metric bolt and a metric wrench should not be used on a standard bolt Afso, most stan dard bolts have slashes radiating out from the center of the head to denote the grade or strength of the bolt, which fs an indication of the amount of torque that can be applied to ft. The greater the number of slashes, the greater the strength of the bolt. Grades 0 through 5 are commonly used on automo biles. Metric bolts have a property class [grade) number, rather than a slash, molded into their heads to indicate bolt strength. In this case, the higher the number, the stronger the bolt, Property class numbers 8 , 8 . 9.8 and 10,9 are commonly used on automobiles. Strength markings can also be used to distinguish standard hex nuts from metric he* nuts. Many standard nuts have dots stamped into one side, while metric nuts are marked with з number. The greater the num ber of dots, or the higher the number, the greater the strength of the nut. Metric studs are also marked on their ends according to property class (grade). Larger studs are numbered {the same as metric bolts), while smaller studs carry a geo metric code to denote grade. It should be noted that many fasteners, especially Grades 0 through 2 , have no dis tinguishing marks on them, When such is the case, the only way to determine whether it is standard or metric is to measure the thread pitch or compare it to a known fastener of the same size. Standard fasteners are often referred to as SAE, as opposed to metric. However, it should be noted that SAE technically refers to a non-metric fine thread fastener only. Coarse thread non-metric fasteners are referred to as USS sizes. Since fasteners of the same size [both standard and metric) may have different Standard (SAE and USS) bolt dimensions/grade marks G Grade marks (bolt strength) L Length (in inches) T Thread pitch (number of threads per inch) D Nominal diameter (in inches) studs or nuts removed from your vehicle in their original locations. Also, when replacing a fastener with a new one, make sure that the new one has a strength rating equal to or greater than the original. Tightening sequences and procedures Most threaded fasteners should be tightened to a specific torque value {torque is the twisting force applied to a threaded com ponent such as a nut or boll}. Overtightening the fastener can weaken it and cause it to break, while undertightening can cause it to eventually come loose. Bolts, screws and studs, depending on the material they are made of and their thread diameters, have fcc-зmvxcsl Metric bolt dimensions/grade marks P Property class (boft strength) L Length (in millimeters) T Thread pitch (distance between threads in millimeters) D Diameter noted in the Specifications at the beginning of each Chapter. Be sure to follow the torque recommendations closely. For fasteners not assigned a specific torque, a general torque value chart is presented here as a guide. These torque values are for dry (unlubricated) fasteners threaded into steel or cast iron (not aluminum). As was previously mentioned, the size and grade of a fastener determine the amount of torque that can sateiy be applied to it. The figures listed here are approximate for Grade 2 and Grade 3 fasteners, Higher grades can tolerate higher torque values. Fasteners laid out in a pattern, such as cylinder head bolts, oil pan bolts, differential cover bolts, etc,, must be loosened or tight ened in sequence to avoid warping the com- strength ratings, be sure to reinstall any bol'tsf specific torque values, many of which are

If a spe cific pattern is not given, the following proce dures can be used to prevent warping. Initially, the bolts or nuts should be assembled finger-tight only. Next, they should be tightened one full turn each, in a criss-cross or diagonal pattern. After each one has been tightened one full turn, return to the first one and tighten them all one-half turn, following the same pattern. Finally, tighten each of them one-quarter turn at a tfme until each fastener has been tightened to the proper torque. To foosen and remove the fasteners, the procedure would be reversed. Component disassembly Component disassembly should be done with care and purpose to help ensure that the parts go back together properly, Always keep track of the sequence in which parts are removed. Make note of special characteristics or marks on parts that can be installed more than one way, such as a grooved thrust washer on a shaft, it is a good idea to lay the disassembled parts out on a clean surface in the order that they were removed. It may also be helpful to make ske ches or take instant photos of compo nents before removat. When removing fasteners from a com- th trach of meir Nations.

Gasket sealing surfaces Throughout any vehicle, gaskets are used to seaF the mating surfaces between two parts and keep lubricants, fluids, vacuum or pressure contained in an assembly. Many times these gaskets are coated with a liquid oa paste-type gasket sealing compound before assembly. Age, heat and pressure can sometimes cause the two parts to stick together so tightly that they are very difficult to separate. Often, the assembly can be loosened by striking it with a soft-face hammer rear the mating surfaces. A regular hammer can be used if a block of wood is placed between the hammer and the part. Do not hammer on cast parts or parts that could be easily damaged. With any particularly stubborn part, always recheck to make sure that every fastener has been removed. Avoid using a screwdriver or bar to pry apart an assembly, as they can easily mar the gasket sealing surfaces of the parts, which must remain smooth. If prying is absolutely necessary, use an ofd broom handle, but keep in mind that extra clean up wifi be nec essary if the wood splinters. After the parts are separated, the old gasket must be carefully scraped off and the gasket surfaces cleaned. Stubborn gasket material can be soaked with rust penetrant or treated with a special chemicaf to soften it so it can be easily scraped off. Caution: Never use gasket removal solutions or caustic chemicals on plastic or other composite com ponents. A scraper can be fashioned from a piece of copper tubing by flattening and sharpening one end. Copper is recom mended because it is usually softer than the surfaces to be scraped, which reduces the chance of gouging the part. Some gaskets can be removed with a wire brush, but regardless of the method used, the mating surfaces must be left clean and smooth. If for some reason the gasket surface is gouged, then a gasket seafer thick enough to fill scratches will have to be used during reassembly of the components. For most applications, a non-drying {or semi * gasket sealer should be usee!, Hose removal tips Warning: If the vehicle fs equipped wfc, conditbning, do not disconnect aoy S Z A/С hoses without first having the depressurrzed by a dealer service d e /J iJ Z ora service station. Hose removal precautions closely parai lei gasket removal precautions. Avoid scratching or gouging the surface that th- hose mates against or the connection may leak. This is especially true for radiator hoses. Because of various chemical reactions, the rubber in hoses can bond itself to the metal spigot that the hose fits over. To rsmovs a hose, first ioosen the hose clamps that secure it to the spigot. Then, with slip-joint pfiers, grab the hose at the clamp and rotate it around the spigot. Worfc it back and forth until it is completely free, then pull it off, Sifi- cone or other lubricants will ease removal if they can be applied between the hose ала the outside of the sprgoL Apply the same lubricant to the inside of the hose and the outside of the spigot to simplify installation. As a last resort {and if the hose is to be replaced with a new one anyway), the rubber can be slit with a knife and the hose peeied from the spigot. If this must be done, be carefuf that the metal connection is not dam aged. If a hose clamp is broken or damaged- do not reuse it. Wire-type clamps usua ^ weaken with age, so it is a good ideai replace them with screw-type clamps № ■ ever a hose is removed.
