Nissan Maximas have been well known for their durability and reliability; however, as with all automobiles, even a Maxima will break down. While there can be many different types of problems with your car, all of which require a wide range of skills and tools, knowing a little about basic mechanics will prove useful in becoming a do-it-yourself mechanic. Additionally, knowing some of the common fixes will save you time and money by being able to do the job yourself.
Open your hood and check the battery connections if the car will not start properly. A low battery can sometimes hold a charge if it still has enough cycles left in it before wearing out completely. Batteries with corrosion on the terminals or loose cables can prevent it from fully recharging or being able to deliver the charge to the starter. Washing corroded terminals off with a bottle of carbonated soda will remove the corrosion.
Replace a failing starter before it gives out completely. Most auto-parts stores will be able to test your starter once it is removed to determine whether or not it needs replacing. Signs of a starter failing include a prolonged time lapse when first turning the key, hearing the "chuga, chuga, chuga" of the starter trying to engage with the flywheel and the Maxima engine actually starting. To find the starter, trace the positive battery cable from the Nissan's battery to the starter, which looks like two cylindrical pieces joined together. Starters are sometimes located directly underneath the car's engine, on top of the engine or beneath the air intake system. If you can access the starter without removing it, tap it lightly with a hammer, which can help it to engage with the flywheel for one or two more starts.
Raise the front of the Maxima using a floor jack and insert jack stands underneath the frame on the jack contact points behind either of the front wheels. Remove the tires and inspect the brake pads. Brake pads with excessive wear can lead to braking failure or permanent damage to the rotors. Unbolt the calipers using a socket or torque wrench and replace the brake pads, remembering to bleed the brakes before driving again.
Check the engine for possible oil leaks or radiator fluid leaks. Oil leaks usually come from worn out gaskets, some of which are easily replaced, such as the front valve cover. Radiator fluid leaks are sometimes also easy to fix if you can determine which hose is allowing the coolant to leak. Always be sure to check fluid levels, such as braking, oil and radiator coolant regularly to keep your Maxima working properly.
Replace drive belts that show signs of wearing out or that have already become frayed. Although not all of the Maxima's belts may be easily accessible, depending on their location and the type of engine configuration, replacing the belts yourself that are accessible can help to prolong the life of your car as well as troubleshoot potential problems.
