Tuneup & Auto Maintenance Tips To Lengthen Your Acura’s Life
An old-fashioned maintenance term that is nearly non-existent today. With electronic ignition and fuel injection came computers that took over control of engine settings. Early versions allowed for some tinkering, but todays engines require advanced equipment and training. You can, however, replace normal maintenance parts and still see improved engine performance from your Acura.
The following are maintenance parts commonly replaced to increase performance and reduce major problems.
Basic Ignition Parts
Spark Plugs: Spark plugs are good indicators of engine condition. Removing and inspecting spark plugs tell you a lot about how well the engine is running and what may be causing problems.
All spark plugs should be removed and checked every 30,000 miles – even if your Acura is “low maintenance” – you are told to change spark plugs at 100,000 miles. This prevents the plugs from seizing in the block, causing expensive repairs down the road.
Always note which plug came from which cylinder. This tells you if a particular cylinder has a problem.
BEWARE: New spark plugs can make a difference in your Acura’s performance but only if replaced with the appropriate OE replacement plug.
Distributor Cap & Rotor: Both the distributor cap and the rotor are usually plastic and, thus, deteriorate with age and use. Cracks may develop, allowing moisture in. The metal contacts on both can then corrode, causing misfiring. These parts should be replaced at recommended intervals or if showing any excessive wear.
Spark Plug Wire Sets: Spark plug wires have become less of a problem than before. New materials and sizing have reduced failures. Electronic ignitions have increased operating ranges.
Now these should be tested for proper resistance before replacement. They are no longer replaced routinely with the cap, rotor and plugs.
According to experts, changing filters on a regular basis may have more to do with your Acura’s longevity than any other single factor.
Oil Filter: Oil filters are easy to replace and help prevent unnecessary engine wear. The job of the oil filter is to remove soot, rust particles and other solid contaminants from the oil. Oil filters should be replaced with engine oil every 3,000 miles.
Air Filter: Air filters remove dirt by trapping particles as air passes through the filter media. They also protect the carburetor in older cars, preventing dirt from clogging the air bleeds and metering jets. They protect fuel injectors in later-model autos.
Air filters should be replaced every 20,000 miles but more often if you live or drive in dusty areas. Any filter that looks heavily loaded should be replaced regardless of the number of miles, as should any filter which shows any type of damage.
PCV Breather Filter: The PCV breather filter assures only clean, filtered air is drawn in through the PCV breather. A clogged breather filter prevents the PCV from siphoning away the blowby gases and moisture created by engine combustion, resulting in oil breakdown and sludge buildup. The PCV breather filter should be replaced every 30,000 miles; however, yearly replacements are a good preventive measure.
Fuel Filter: Contaminants can get into your fuel system and if not trapped by the fuel filter, they can clog the injector inlet screens. If dirt reaches the injector itself, it can clog or damage the pintle valve and seat. In older cars, dirt can plug the carburetors fuel metering orifices.
If the fuel filter is not replaced regularly, fuel flow to the engine will become restricted, resulting in stalling, loss of high speed power and hard starting. The fuel filter should be replaced every 30,000 miles; however, professionals recommend a yearly fuel filter change and a change whenever other fuel system parts are replaced.
Automatic Transmission Filter: Properly filtered transmission fluid transmits energy, plus it cools and lubricates the moving parts of the transmission.
A clogged transmission filter can produce transmission slippage, engagement problems and hesitation. Experts recommend this filter be changed every 12,000-15,000 miles to extend the life of your automatic transmission.
Other Acura Maintenance Parts
Many maintenance parts are mistakenly seen as non-critical. Though not true “tuneup” parts, the functions of these parts can definitely impact the benefit of any tuneup. Plus, as emission laws have gotten more stringent, these parts have become essential – if you want your Acura to pass emissions the first time around.
Oxygen Sensor (O2 Sensor): Your oxygen sensor(s) should be replaced at the recommended intervals. A worn oxygen sensor drastically changes engine settings. For more information on oxygen sensors, see the tech article Acura Oxygen Sensor Repairs
Vacuum Hoses: Many major systems depend on manifold vacuum for signals and function. All vacuum hoses should be checked and replaced as needed. Even a slight leak can cause major problems with performance; in some cases, the car wont even run if theres a vacuum leak.
Temperature Sensors: Temperature sensors for various engine functions can also be a good weekend project. These sensors control the fuel injection system, cooling system and even the exhaust system. And they can definitely be a cause of poor performance problems.
Important Tips to Remember
Heed these tips and you are well on your way to extending the life of your Acura and improving its overall performance – especially gas mileage and emissions:
Tip #1: General overall cleanliness of your engine is the best preventive maintenance you can perform on your Acura. A clean engine runs cooler and is much less likely to cause premature failure of other parts. Its also easier to work on.
Tip #2: Regular routine replacement of all filters, lubricants, coolant and the other parts noted here is critical. Use the mileage guidelines shown as your benchmark. Sensing and mechanical tolerances have become so tight even slight variations can create drastic performance changes.
Tip #3: Know your Acuras systems and particular requirements before starting any project. Do not attempt to fix what you dont understand.
Tip #4: Remember that some improvements may not take effect right away if your Acuras computer is designed to learn and adjust. The computer may need to see various parameters before making any permanent setting changes.
