FAQ’s

AA Auto Repair & Tires wants to make sure you don’t spend unnessary dollars on un-needed service. Check out some of our Frequently Asked Questions regarding Brake Service

What Does It Mean When My Brakes Squeak?

Brake pads are built with a special feature that?s automatically activated when they have worn out past their useful life.

Simply, a metal tab or blade is attached to the brake pad, where it hovers just above the brake rotor. As the brake pads wear out (just like your pencil eraser), they get thinner, which brings the metal tab closer and closer to the metal brake rotor.

At some point, the brake pad material will hit its minimum safe thickness. Here, the metal tab physically contacts the metal brake rotor, where it generates an irritating squealing sound. This is an audible signal from your brakes that it?s time to replace those worn out brake pads.

Just remember that brakes sometimes squeal or squeak, but not as a result of component wear. In any case, drivers should have their brakes inspected to determine the root cause of any unexpected noise.

Why is my car is leaking oil.

Sometimes these components will erode over time, but more likely than not, if you have this kind of leak, it?s because you have old, dirty oil?perhaps because you have not had your oil changed recently enough.

Damaged Oil Gaskets or Pans

Your vehicle?s oil pans and gaskets can easily be damaged by road debris since they are located at the bottom of the engine. Rough roads can lead to a hole which will cause an oil pan leak. The pan?s gasket usually suffers a lot of wear and tear, or it can also get damaged, which leads to an oil gasket leak.?

Incorrect Installations

It may happen that one of the gaskets that keep oil inside is Improperly installed. Most commonly, this happens when the oil pan gasket or valve cover gasket are over-tightened. It can also happen when tightness is not evenly distributed. Another reason can be the improper attachment of the oil filter, as the engine oil flows continuously through it, and if it?s loose, you can experience a leak there.?

Bad Rings or Valve Seals

Leaking rings or valve seals can also be contributing to your car losing oil. However, if there are no holes in your gaskets, the oil will not make it outside the engine, so you won?t notice it, as it will get burned up in the combustion process.?

Regardless of the specific cause, it is urgent to stop an oil leak, so take your vehicle to the Meineke shop immediately. Following the oil leak, you may encounter the smell of burnt oil, followed by blue smoke and ultimately some major damage to your engine. Do not delay in addressing this issue.

 

Why is my Engine Temperature Light is On.

Indicator light means the engine temperature has exceeded normal limits. Check coolant level, fan operation, radiator cap, coolant leaks.?

Why is my oil pressure warning light is on.

Indicator light means loss of oil pressure, meaning lubrication is low or lost completely. Immediately check the oil level and pressure.

why is my check engine light on?

If your light stays illuminated, the car?s diagnostic systems have detected a malfunction that needs to be investigated. Often it’s a manufacturer’s warning all suggesting routine maintenance. It’s a good idea to look at your milelage and see if it’s past a certain vehicle milestone. The most common errors reported by CarMD are as follows:

    1. (tie) Replace ignition coil(s) and spark plug(s) ($391.42)
    1. (tie) Replace oxygen sensor(s) ($244.04)
    3. Replace catalytic converter(s) with a new OEM catalytic converter(s) ($1,371.17)
    4. Inspect for loose gas cap and tighten or replace as necessary ($25.86)
    5. Replace ignition coil(s) ($217.91)
    6. Replace evaporative emissions purge control valve ($149.52)
    7. Replace mass airflow sensor ($340.58)
    8. Replace evaporative emissions purge solenoid ($153.70)
    9. Replace fuel injector(s) ($449.73)
    10. Replace thermostat ($244.61)

Also, newer cars have detailed notifications in your dash panel’s computer. Sometime’s it is difficult manuevering your cars computer but your owners manuel will save you a lot of time.

Why is my car's exhaust really dark or black?

?Clogged Air Filters.

With dust blocking the air filter, there are chances that sufficient air amount is not reaching the cylinder. As a result, more fuel is being burnt. And, ultimately this causes black smoke from exhaust irrespective of the fact that the fuel injectors are working properly. Besides this, due to the heavy load or during hard acceleration also black smoke can be found, as the fuel is not injected at the right time.

Damaged Fuel Injectors

In case of the good fuel injector, the fuel is properly atomized, which means the fine droplets of fuel are spreading equally in the cylinder. However, if the injectors don?t close on time or they are clogged, there are chances that more fuel is injected in a certain area called as rich mixture area of the car. In this situation, even the amount of air is insufficient for the combustion of fuel due to blocked injectors (and the few opened ones inject only fuel).

Faulty MAF Sensor

The work of Mass Airflow sensor is to determine the volume of air entering the engine, which in turn, helps in measuring the amount of fuel to be injected inside the cylinder. This entire functioning is important for the complete combustion of fuel in the engine. Otherwise, a malfunctioning MAF sensor can lead to poor performing engine.

Bad EGR Valve

The EGR reduces emission of nitrogen oxides by re-circulating portion of an engine?s exhaust gas to the internal combustion engine. If this component is damaged, it emits all the black smoke out of exhaust.

Damaged Piston Rings

Piston Rings are designed to prevent the infiltration of engine oil inside the combustion chamber. If there is any problem with the piston rings, the engine oil starts flowing into the combustion chamber. The combustion of the mixture of this engine oil and the fuel delivers black smoke.

Engine Deposits Engine

deposits are another reason causing black smoke from tailpipe. When the engine is new, it will run fluently without any problems. But after a long period of use, the engine conditions get worse and worse and this consists of getting accumulations of combustion product in important areas like combustion chambers and injectors. And these interfere with best functioning.

Why does my engine make a knocking noise?

Knocks are generally the result of improper octane, poor fuel quality, or engine or sensor issues. Each vehicle is equipped with a knock sensor that communicates to the vehicle?s computer to adjust the timing to compensate for any problems have been identified. The sensor creates a voltage signal based on the vibrations/noises caused by a problem. The computer takes the information to adjust timing when a spark knock occurs. Knock sensors are typically located on the engine block, cylinder head, or intake manifold. This allows it to sense the vibrations caused by the engine knock or combustion. The PCM, or powertrain control module, utilizes the signal to adjust the ignition timing and prevent pre-ignition, if necessary. If the knock sensor is not working properly, you may notice such symptoms as:?

    • Decrease in mileage
    • Loss of power
    • Decrease in acceleration
    • Emitting higher emissions
    • Check engine light illuminating

Terminology

^

Valves

The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. Note that both valves are closed during compression and combustion so that the combustion chamber is sealed.

^

piston

A piston is a cylindrical piece of metal that moves up and down inside the cylinder and provides the motion to turn your axels through the crank shaft. Notice the image below…the pistons are moving up and down by an explosion of gas that pushes the piston in the opposite direction.

^

piston rings

Piston rings provide a sliding seal between the outer edge of the piston and the inner edge of the cylinder. The rings serve two purposes:

  1. They prevent the fuel/air mixture and exhaust in the combustion chamber from leaking into the sump during compression and combustion.
  2. They keep oil in the sump from leaking into the combustion area, where it would be burned and lost.

Most cars that “burn oil” and have to have a quart added every 1,000 miles are burning it because the engine is old and the rings no longer seal things properly. Many modern vehicles use more advance materials for piston rings. That’s one of the reasons why engines last longer and can go longer between oil changes.

^

Crankshaft

The crankshaft turns the piston’s up-and-down motion into circular motion just like a crank on a jack-in-the-box does.

^

rotors

A brake rotor is a substantial metal disk that sits just behind each wheel. It’s not actually attached to the wheel, but it is attached directly to the axle. When you apply pressure to the brake pedal, a pair of brake pads clamp the disk from either side. The friction created slows the vehicle or brings it to a stop.
^

sump

The sump surrounds the crankshaft. It contains some amount of?oil, which collects in the bottom of the sump (the oil pan).

^

spark plug

The spark plug?supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must happen at just the right moment for things to work properly.
