Introduction to the Nissan Nissan Maxima models are available in 4-door sedan and station wagon body styles. The transversely mounted V6 engine used in these models is equipped with electronic fuel injection. The engine drives the front wheels through either a 5-speed manual or 4-speed automatic transaxle via independent driveaxles.

as follows:
Retail auto parts stores: Good auto parts stores will stock frequently needed components which wear out relatively fast, such as clutch components, exhaust systems, brake parts, tune-up parts, etc. These stores often supply new or reconditioned parts on an exchange basis, which can save a considerable amount of money. Discount auto parts stores are often very good places to buy materials and parts needed for general vehicle
maintenance such as oil, grease, filters, spark plugs, belts, touch-up paint, They also usually seli tools and general accessories, have con-
venient hours, charge lower prices and can often be found not far from
home. Authorized dealer parts department: This is the best source for parts which are unique to the vehicle and not generally available elsewhere (such as major engine parts, transmission parts, trim pieces, etc.). Warranty information: If the vehicle is still covered under warranty, be sure that any replacement parts purchased - regardless of the source - do not invalidate the warranty! To be sure

machine shops can perform this task, as well as other repair procedures, such as the repair of threaded holes that have been stripped out. Flat washers and lockwashers, when removed from an assembly, should always be replaced exactly as removed. Replace any damaged washers with new ones. Never use a lockwasher on any soft metal surface (such as aluminum), thin sheet metal or plastic.

between standard (sometimes called U.S. or SAE) and metric hardware, since they cannot be interchanged. All bolts, whether standard or metric, are sized according to diameter, thread pitch and length. For example, a standard 1/2 - 13 x 1 bolt is 1/2 inch in diameter, has 1 3 threads per inch and is 1 inch long. An M1 2 - 1 .75 tell

in diameter, thread pitch and length, metcan also be distinguished by examining the bolt heads. To begin with, the distance across the flats on a standard bolt head is measured in inches, while the same dimension on a metric bolt is sized in millimeters (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

It should be noted that many fasteners, especially Grades through have no distinguishing marks on them. When such is the case, the only way to determine whether 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, should be noted that SAE technically refers to a non-metric fine thread'fastener only. Coarse thread non-metric fasteners are referred

Tightening sequences and procedures Most threaded fasteners should be tightened to a specific torque value is the twisting force applied to a threaded component such as a nut or bolt). Overtightening the fastener can weaken it and cause it to break, while undertightening can cause to eventually come loose. Bolts, screws and studs, depending on the material they are made of and their thread diameters, have specific torque values, many of which are 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

When
removing fasteners from a component, keep track of their locations. Sometimes threading a bolt back in a part, or putting the washers and nut back on a stud, can prevent mix-ups later. If nuts and bolts cannot be returned to their original locations, they should be kept in a compartmented box or a series of small boxes. A cupcake or muffin tin is ideal for this purpose, since each cavity can hold the bolts and nuts from a particular area (i.e. oil pan bolts, valve cover bolts, engine mount bolts, etc.). A pan of this type is especially helpful when working on assemblies with very small parts, such as the carburetor, alternator, valve train or interior dash and trim pieces. The cavities can be marked with paint or tape to identify

Whenever wiring looms, harnesses or connectors are separated, it is a good idea to identify the two halves with numbered pieces of masking tape so they can be easily reconnected.
Gasket sealing surfaces Throughout any vehicle, gaskets are used to seal 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 or paste-type gasket sealing compound before assembly. Age, heat and pressure can some-

times 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 near the mating surfaces. A regular hammer can be used if a block of wood is placed between the hammer and the part. Do not

If prying is absolutely necessary, use an old broom handle, but keep in mind that extra clean up will be necessary 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 chemical to soften it so it can be easily scraped off. A scraper can be fashioned from a piece of copper tubing by flattening and sharpening one end. Copper is recommended 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 sealer thick enough to fill scratches will have to be used during reassembly of the components. For most applications, a nondrying (or semi-drying) gasket sealer should be used.

To help the owner decide which tools are needed to perform the tasks in this manual, the following tool lists are offered: Maintenance and minor repair, Repair/overhaul and Special. The newcomer to practical mechanics should start off with the maintenance and minor repair tool kit, which is adequate for the simpler jobs performed on a vehicle. Then, as confidence and experience grow, the owner can tackle more difficult tasks, buying additional tools as they are needed. Eventually the basic kit will be expanded into the repair and overhaul tool set. Over a period of time, the experienced do-it-yourselfer will assemble atool set complete enough for most repair and overhaul procedures and will add tools from the special category when it is felt that the expense is justified by the frequency of use. detailed

If, on the other hand, extensive work is planned, it would be a good idea to purchase a modest tool set from one of the large retail chain stores.

a tool box. As additional tools are needed, add-on sets, and a larger tool box can be purchased to expand the tool selection. Building a tool set gradually allows the cost of the tools to be spread over a longer period of time and gives the mechanic the freedom to choose only those tools that will actually be used. Tool stores will often be the only source of some of the special tools that are needed, but regardless of where tools are bought, try to avoid cheap ones, especially when buying screwdrivers and sockets, because they won't last very long. The expense involved in replacing cheap tools will eventually be greater than the initial cost of quality tools. often

Some tools, such as screwdrivers, pliers, wrenches and sockets, can be hung on a panel mounted on the garage or workshop wall, while others should be kept in a tool box or tray. Measuring instruments, gauges, meters, etc. must be carefully stored where they cannot be damaged by weather or impact from other tools. When tools are used with care and stored properly, they will last a very long time. Even with the best of care, though, tools will wear out if used frequently. When a tool is damaged or worn out. replace it. Subsequent jobs will be safer and more enjoyable if you do.

be overlooked when discussing tools is the workshop. If anything more than routine maintenance is to be carried out, some sort of suitable work area is essential. It is understood, and appreciated, that many home mechanics do not have a good workshop or garage available, and end up removing an engine or doing major repairs outside. It is recommended, however, that the overhaul or repair be completed under the cover of a roof. A clean, flat workbench or table of comfortable working height is an absolute necessity. The workbench should be equipped with a vise that has a jaw opening of at least four inches. As mentioned previously, some clean, dry storage space is also required for tools, as well as the lubricants, fluids, cleaning solvents, etc. which soon become necessary. Sometimes waste oil and fluids, drained from the engine or cooling system during normal maintenance or repairs, present a disposal problem. To avoid pouring them on the ground or into a sewage system, pour the used fluids into large containers, seal them with caps and take them to an authorized disposal site or recycling center. Plastic jugs, such as old Not

To help keep the area under the vehicle clean, a large cardboard box can be cut open and flattened to protect the garage or shop floor. Whenever working over a painted surface, such as when leaning over a fender to service something under the hood, always cover it with an old blanket or bedspread to protect the finish. Vinyl covered pads, made especially for this
purpose, are available at auto parts stores.

Towing As a general rule, the vehicle should be towed with the front (drive) wheels off the ground. If they can't be raised, place them on a dolly. The ignition key must be in the Ace position, since the steering lock mechanism isn't strong enough to hold the front wheels straight while towing. Vehicles equipped with an automatic transaxle should be towed with

Before towing, check the transmission fluid level (see Chapter 1 ). If the level is below the Hot line on the dipstick, add fluid or use a towing dolly. Release the parking brake, put the transaxle in Neutral and place the ignition key in the Ace position. Caution: Never tow a vehicle with an automatic transaxle from the rear with the front wheels on the ground. Equipment specifically designed for towing should be used.

The recommended weight of the oil depends on the season, temperature and the demands on the engine. Light oil is used in cold climates and under light load conditions. Heavy oil is used in hot climates and where high loads are encountered. Multi-viscosity oils are designed to have characteristics of both light and heavy oils and are available in a number of weights from 5W-20 to 20W-50. tains a

Chassis and wheel bearing grease is a heavy grease used where increased loads and friction are encountered, such as for wheel bearings, balljoints, tie-rod ends and universal joints. High-temperature wheel bearing grease is designed to withstand the extreme temperatures encountered by wheel bearings in disc brake equipped vehicles. It usually contains molybdenum disulfide (moly), which is a dry-type lubricant.

a special extreme pressure lubricant, usually containing moly, used to lubricate high-load parts (such as main and rod bearings and cam lobes) for initial start-up of a new engine.

Oil additives range from viscosity index improvers to chemical treat-
ments that claim to reduce internal engine friction. It should be noted that most oil manufacturers caution against using additives with their oils.
Gas additives perform several functions, depending on their chemical makeup. They usually contain solvents that help dissolve gum and varnish that build up on carburetor, fuel injection and intake parts. They also serve to break down carbon deposits that form on the inside surfaces of the combustion chambers. Some additives contain upper cylinder lubricants for valves and piston rings, and others contain chemicals to remove condensation from the gas tank.

Regardless of how enthusiastic you may be about getting on with the job at hand, take the time to ensure that your safety is not jeopardized. A moment's lack of attention can result in an accident, as can
observe certain simple safety precautions. The possibility of an accident will always exist, and the following points should not be considered a comprehensive list of all dangers. Rather, they are intended to make you aware of the risks and to encourage a safety conscious approach to all work you carry out on your vehicle. failure to

a jack when working under the vehicle. Always use approved jackstands to support the weight of the vehicle and place them under the recommended lift or support points. DON'T attempt to loosen extremely tight fasteners (i.e. wheei lug nuts) while the vehicle is on a jack — it may fall. DON'T start the engine without first making sure that the transmission is in Neutral (or Park where applicable) and the parking brake is set. DON'T remove the radiator cap from a hot cooling system — let it cool or cover it with a cloth and release the pressure gradually. DON'T attempt to drain the engine oil until you are sure it has cooled to the point that it will not burn you. DON'T touch any part of the engine or exhaust system until it has cooled sufficiently to avoid burns. DON'T siphon toxic liquids such as gasoline, antifreeze and brake fluid by mouth, or allow them to remain on your skin. DON'T inhale brake lining dust — it is potentially hazardous (see Asbestos below) DON'T allow spilled oil or grease to remain on the floor — wipe it up before someone slips on it. DON'T use loose fitting wrenches or other tools which may slip and cause injury. DON'T push on wrenches when loosening or tightening nuts or bolts. rely
Always
try to pull the wrench toward you. If the situation calls for pushing the wrench away, push with an open hand to avoid scraped knuckles if the wrench should slip. DON'T attempt to lift a heavy component alone — get someone to
help you. DON'T rush or take unsafe shortcuts to finish a job. DON'T allow children or animals in or around the vehicle while you are working on it. DO wear eye protection when using power tools such as a drill, sander,
bench grinder, etc. and when working under a vehicle. DO keep loose clothing and long hair well out of the way of moving parts.
DO make adequate

have any kind of open flame around when working on a vehicle. But the risk does not end there. A spark caused by an electrical short circuit, by two metal surfaces contacting each other, or even by static electricity built up in your body under certain conditions, can ignite gasoline vapors, which in a confined space are highly explosive. Do not, under any circumstances, use gasoline for cleaning parts. Use an approved safety solvent. Always disconnect the battery ground (-) cable at the battery before working on any part of the fuel system or electrical system. Never risk spilling fuel on a hot engine or exhaust component. It is strongly recommended that a fire extinguisher suitable for use on fuel and electrical fires be kept handy in the garage or workshop at all times. Never try to extinguish a fuel or electrical fire with water. or
Fumes Certain fumes are highly toxic and can quickly cause unconsciousness and even death if inhaled to any extent. Gasoline vapor falls into this category, as do the vapors from some cleaning solvents. Any draining or pouring of such volatile fluids should be done in a well ventilated area.
When using cleaning fluids and solvents, read the instructions on the container carefully. Never use materials from unmarked containers. Never run the engine in an enclosed space, such as a garage. Exhaust fumes contain carbon monoxide, which is extremely poisonous. If you need to run the engine, always do so in the open air, or at least have the rear of the vehicle outside the work area. If you are fortunate enough to have the use of an inspection pit, never drain or pour gasoline and never run the engine while the vehicle is over the pit. The fumes, being heavier than pit with possibly lethal results.

Asbestos Certain friction, insulating, sealing, and other products — such as brake linings, brake bands, clutch linings, torque converters, gaskets, etc. — contain asbestos. Extreme care must be taken to avoid inhalation of dust from such products since it is hazardous to health. If in doubt, assume that they do contain asbestos.

system voltage
severe electric shock can result from touching certain parts of the ignition system (such as the spark plug wires) when the engine is running or being cranked, particularly if components are damp or the insulation is defective. In the case of an electronic ignition system, the secondary system voltage is much higher and could prove fatal.

always establish a clear idea of why a problem has occurred and take steps to ensure that it doesn't happen again. If the electrical system fails because of a poor connection, check the other connections in the system to make sure that they don't fail as well. If a particular fuse continues to blow, find out why - don't just replace one fuse after another. Remember, failure of a small component can often be indicative of potential failure or incorrect functioning of a more important component or system. Finally,

in relatively good running condition and the need for additional work be minimized. More likely than not, however, there will be times when the engine is running poorly due to lack of regular maintenance. This is even more likely if a used vehicle, which has not received regular and frequent maintenance checks, is purchased. In such cases, an engine tune-up will be needed outside of the regular routine maintenance intervals. The first step in any tune-up or diagnostic procedure to help correct a poor running engine is a cylinder compression check. A compression check (see Chapter 2 Part B) will help determine the condition of internal engine components and should be used as a guide for tune-up and repair procedures. If, for instance, a compression check indicates serious internal engine wear, a conventional tune-up will not improve the performance of the engine and would be a waste of time and money. Because of its importance, the compression check should be done by someone with the right equipment and the knowledge to use it properly. The following procedures are those most often needed to bring a generally poor running engine back into a proper state of tune.

This Chapter
is
designed to help the home mechanic maintain the maximum performance, economy, safe-
Nissan Maxima with the goals of ty and reliability in mind.
Included is a master maintenance schedule (page 34), followed by procedures dealing specifically with each item on the schedule. Visual
checks, adjustments, component replacement and other helpful items are included. Refer to the accompanying illustrations of the engine compart-
ment and the underside
of the vehicle for the locations of various
compo-
nents.
Servicing your vehicle
in
accordance with the planned mileage/
time maintenance schedule and the step-by-step procedures should re-

should, be grouped together because of the nature of the
procedures or because of the proximity of two otherwise unrelated components or systems. For example, if the vehicle is raised for chassis lubrication, you should inspect the exhaust, suspension, steering and fuel systems while you're under the vehicle. When you're rotating the tires, it makes good sense to check the brakes since the wheels are already removed. Finally, let's suppose you have to borrow or rent a torque wrench. Even if you only need it to tighten the spark plugs, you might as well check the torque of as many critical fasteners as time allows. The first step in this maintenance program is to prepare yourself before the actual work begins. Read through all the procedures you're planning to do, then gather up all the parts and tools needed. If it looks like you might run into problems during a particular job, seek advice from a mechanic or experienced do-it-yourselfer.
