This section provides the information necessary for the owner of the Toyota Corolla and its variants to maintain the vehicle's high performance, fuel economy, driving safety and durability.
The main maintenance intervals with the list of required work are given below, followed by sections describing the content of each type of work. This work includes visual inspections, adjustments and replacement of components, which are described together with other useful recommendations. To make it easier to locate a particular component or assembly, illustrations of the vehicle layout from the engine compartment and underbody side are provided.
Vehicle maintenance is planned according to mileage or time in service. The following sections describe the sequence of operations for care and maintenance, which will keep the vehicle in good working condition for a long time. The maintenance procedure is structured so that all vehicle components must be serviced at the specified intervals; neglecting the care of individual systems and components reduces the effectiveness of maintenance.
When servicing the Corolla, you will find that most work can and should be performed together. This is because the procedures are almost identical, or because components with completely different functions are located next to each other.
For example, if you have raised the vehicle for any reason, while under the vehicle you should also check the exhaust system, suspension, steering and fuel system components. When rotating the wheels, which involves removing them, it is advisable to check the condition of the brakes and wheel bearings.
Finally, suppose you have borrowed or rented a torque wrench. If you only need to tighten the spark plugs, you may also check the torque of the other fasteners.
The first step in performing this maintenance program is self-preparation. Study all sections relating to the procedures you intend to perform, make a list, and prepare all parts and tools needed for the work. If you feel that you cannot complete some part of the procedure on your own, consult your local parts store or your dealer's service department.
