The correct tire pressure for a vehicle is determined by the size and weight of the vehicle, the type of tires it uses, load hauled, and the type of driving the vehicle is intended for. The vehicle manufacturer places a tire inflation placard in each vehicle that gives the proper tire inflation pressures for that vehicle. This placard is located on the inside of the glove box door, inside the fuel-filler door, or on the driver’s side doorpost (depending upon manufacturer). Most manufacturers also list tire inflation levels in the owner’s manual.
According to automotive experts, regularly scheduled oil/filter changes are the single most important item for prolonging engine life. Most new vehicles have recommended oil/filter change intervals of 7,500 miles and some new vehicles have recommended oil change intervals of 11,000 to 15,000 miles under normal operating conditions, with “”normal”” operation described as the operation of the vehicle for at least 20 minutes at a medium speed, with a steady throttle and in a clean driving environment.
Short hops to the store, stop-and-go rush hour driving, driving on dirt roads and inclement-weather operation are all considered severe operating conditions that can cause impurities to build up quickly in the oil, resulting in increased wear and tear on internal parts. That is why most owner’s manuals and mechanics recommend changing the oil and filter every three months or 3,000 miles (whichever comes first) to assure that maximum engine lubrication occurs while a minimum of impurities are suspended in the oil. To find out what the recommended oil change frequency is for your vehicle, check your owner’s manual or talk with your automotive service professional.
It is impossible to determine the condition of the coolant in the radiator just by looking at it. Coolant, a mixture of ethylene glycol and water, breaks down with age, picks up contaminants that cause sludge, and becomes acidic. When this happens, it can cause corrosion within the radiator and cooling passages of the engine. To determine its condition, coolant must be checked with coolant test strips that measure PH balance. Coolant is an environmentally hazardous substance. It pollutes the water table and is poisonous to people and animals and therefore must be disposed of as a hazardous waste. Your mechanic has special tools and procedures for testing and changing coolant.
The term “tune-up” actually applies only to older cars without electronic ignition (before 1981). On these vehicles a tune-up would generally be required every 15,000 – 20,000 miles and consisted of replacing the spark plugs, ignition contact points, rotor and distributor cap and adjusting the ignition timing as well as the carburetor.
On modern vehicles equipped with electronic ignition, fuel injection and computer controls, the term “engine performance maintenance” is a more accurate term. A “tune-up” for these newer vehicles is an orderly process of inspection, computer diagnosis, testing and adjustment to maintain peak engine performance, maximum operating efficiency and low exhaust emissions. During this process, spark plugs, plug wires, sensors, and modules may be replaced. The frequency at which a newer vehicle needs a tune-up is dependent more upon driving conditions than mileage and recommended tune-up frequencies vary between 30,000 – 100,000 miles, depending on the manufacturer. To learn how often your vehicle needs a tune-up, check your owner’s manual or speak with your local automotive service provider.
Most car care experts advise having an automatic transmission’s fluid and filter changed every two years or 24,000 miles, to keep it in good working order. This is especially important if the vehicle is more than five years old. Many vehicles newer than five years old may need scheduled service less often and some new vehicles have transmissions that need no scheduled service for the life of the car.
By-the-book service, however, may not be adequate if your vehicle is driven hard, tows a trailer, goes off-road or carries a camper. Under these conditions, the fluid and filter may need to be changed more often — every 12 months or 12,000 miles –because dirt and moisture buildup in the fluid can cause internal damage. Heat buildup can also be a problem. The harder the transmission works, the hotter the fluid gets and the quicker the fluid breaks down. To find out the recommended service schedule for your vehicle’s transmission, check the owner’s manual or talk with your local automotive service provider.
Manual transmissions generally need no regularly scheduled service, but may need service due to worn clutch and throw-out bearings and broken synchromesh gears. Check your owner’s manual for specific information on manual transmission service or talk with your local automotive service provider.
You have invested a lot of money to purchase your vehicle, so you need to maintain your vehicle properly. This is not the only reason to take regular vehicle maintenance seriously. There are several other factors that can be considered.
Preventive car care reduces the wear and tear of engine parts and other components and this extends the life of your vehicle. Keeping up with the regular maintenance schedule can help by preventing costly repairs of the cooling system, transmission system, drivetrain, and other components.
Increased Safety
The last thing anyone wants when driving their car is to experience and unexpected breakdown. A breakdown at night on a quiet road can be a dangerous situation. Who can predict what might happen when you are stranded in a remote place? Or what about breaking down on a narrow bridge, or during rush hour? Regular maintenance reduces the probability your car’s mechanics will fail without warning.
Reduced Repair Costs
Regular maintenance doesn’t cost much in comparison to unexpected repairs and replacements which can be expensive. Regular maintenance of your vehicle gives your mechanic an opportunity to check whether there are any signs of minor problems like cracks, leaks, as well as excessive wear and tear due to friction. If you pay attention to these details, often the specific part can be saved and you can save time and money.
Here are some common areas that need routine, periodic maintenance:
