The tables of sizes and adjustments are given in the appendix at the end of the book. The necessary sizes and adjustment data are not always given in the description, but they are contained in the mentioned tables. It should be especially noted that in order to avoid errors, you should make sure that the data is suitable for your model, as there are differences between a sedan, a combi (coupe) and a station wagon.
Routine operations such as "open the engine hood" before working in the engine compartment, or "loosen the wheel nuts" before removing the wheel, are not always specified because they are taken for granted.
Complex work, on the contrary, is described in more detail. Below are the most important instructions that must be followed when performing repair work:
- Install nuts and bolts clean and lightly lubricated. Check the integrity of the nut and threaded surfaces and remove any burrs. If in doubt, it is better to install new nuts and bolts. Always install new self-locking nuts.
- Do not degrease nuts and bolts.
- The bolts installed on the car have certain characteristics and cannot be replaced with others. The bolt heads have numbers on them that indicate their hardness. Number 7 is for the highest tightening torques, and number 4 is for the weakest tightening torques. Do not install a bolt with a lower hardness number.
- Maintain the tightening torques given in the table. The tightening torque data is grouped according to chapters and is therefore easy to find.
- All sealing washers, gaskets, locking elements, cotter pins and sealing rings must be replaced during assembly. Seals must also be replaced when the seal is removed. Lubricate the seal lips before installing it. Install the seal so that its lips prevent oil or grease from leaking out.
- If the left or right side of the car is indicated, it is meant in relation to the forward direction, the same applies to the concepts of "front" and "rear". If necessary, a special explanation is given in the description.
- It is very important to have reliable supports when working with the brake system, wheel suspension and generally under the car. The onboard jack is intended only for changing a wheel on the road. If it is necessary to use it during repairs, then only to lift the car and lower it onto the appropriate supports. It is better to install these tripod supports when using a garage jack. Do not put bricks under it, at least when using blocks with a large support surface, use with a sufficiently strong wooden pad. Chapter 1.5 describes how to lift a car using a lift.
- Lubricants, oils, underbody protection and all mineral substances corrode rubber parts of the body and brake system. Particularly avoid contact with such substances, including fuel, parts of hydraulic devices. Clean parts of the brake system only with brake fluid or alcohol. It should be especially taken into account that brake fluid is poisonous and corrodes paint.
- When performing repair work, install only original TOYOTA parts. To avoid any difficulties later, it is better to refuse to install any other parts. The exception is those parts of electrical equipment for which there is appropriate permission from the manufacturer.
- When purchasing parts and components, it is necessary to indicate the exact model designation with the chassis number, and in certain cases the engine number and year of manufacture. This will speed up the delivery of parts and avoid errors.
- All work on the car, especially with the brake system and steering, must be done very carefully. The operational safety of the car must be ensured during each repair.
The following precautions should be carefully observed:
- When disconnecting hoses, pull only at the end, not at the middle of the hose.
- When disconnecting connectors, grasp only the connector, not the wire.
- Prevent electrical components such as relays or sensors from falling. If they fall onto a hard surface (for example, on the ground) they should be replaced. Do not install these parts on the vehicle.
- When connecting a vacuum gauge, do not connect a hose that has a diameter larger than the fitting.
