How to Fix an Oil Leak

Normally, cars experience a wide range of leaks, ranging from automatic transmission fluid leak to that of windshield washer fluid. However, none of these leaks is as common as an engine oil leak. Engine oil plays the dual role of a coolant and lubricant, so it’s obvious that its shortage will reflect badly on the overall functioning of the car. Thus, it is important to find and fix the leak before it leads to further complications.

How to Diagnose and Fix an Oil Leak?

A small pool of oil beneath your car is the most obvious sign of an oil leak. However, it is highly unlikely that you will check the ground just to see if there are any traces of oil. The simplest method of diagnosing this problem is to spread a newspaper beneath the car at night and check it for oil stains the next morning.

The next step is to find the source of leak beneath the hood. It will be difficult to trace the leak in an engine totally smeared with oil, and hence, you will have to degrease it to find the source. Check all the bolts in the engine, as loose bolts are most likely to cause oil leak. You can also use a dipstick to determine whether you are losing oil; this is yet another indicator of an underlying leak.

Issues With the Valve Cover and Oil Filter
In most of the cases, engine oil leak is traced to valve covers―loosening of bolts which fix the valve covers to be precise. If the leak is not very serious, you can simply tighten the cover bolts and the problem will be fixed. However, if the problem is major you may have to opt for new valve cover gasket to fix the same.

Besides this, you also need to note

Symptoms of a Bad Control Arm Bushing

Symptoms of a bad control arm bushing
Did You Know?
Control arms have been used in automobile suspensions for close to a century.
Most people consider a vehicle’s entire suspension system as ‘one’ part. The fact is, it is made up of several components which play different roles. One such component is the control arm, which is mostly found in the front wheels, though some trucks and cars have it in the rear ones too. It connects the front suspension of the vehicle to its frame. There are two control arms in the suspension―upper and lower―and they contain a rubber bushing at the end. This is made up of a rubber lining encased between two metal sleeves.Such placement and compact design of the bushing is done on purpose; it helps cushion the vehicle from small bumps and vibrations, which a spring cannot. The inner metal sleeve is connected to car frame via a center bar. The outer sleeve is connected to the wheel assembly via the control arm. Thus, both the sleeves move independently from each other, and it is the rubber bushing which provides a lubrication between them. Considering that they bear a huge amount of stress with every drive, these bushings wear out pretty fast by becoming hard and cracking. Let us see how to identify a bad control arm bushing from its symptoms.

Steering problems are one of the first indications of a damaged control bushing. The steering may lose a bit of its responsiveness. At high speeds, it may even start ‘wandering’, or make the vehicle turn erratically. The driver can feel the wheel vibrate while in motion. The vehicle may start leaning to one side, to some degree, when taking sharp turns.

Speedometer Not Working Properly

Did You Know?
Before the invention of the speed gun, cars in the early 20th century were required to have two speedometers, one on the dashboard and one on the front fender, so that police could see how fast they were going!
A speedometer is an instrument which provides the driver with instantaneous readings of speed. Traditional speedometers used gears and wires to determine speed, while most modern vehicles use speed sensors for the same. Common problems include, a faulty sensor, bad wiring, or dial malfunctions. Troubleshooting speedometer problems mostly call for a replacement of the speed sensor or cable, depending upon the vehicle. Both these repair jobs are simple to perform and can be done at home.
Common Speedometer Problems
My speedometer is dead!
This could be due to two reasons. In older cars a break in the cable that connects the transmission to the speedometer is the most common cause. Cars produced after 1990 are usually equipped with speed sensors, which may crash and cease to transmit speed readings to the speedometer. A more serious problem could be a faulty speedometer head, which needs expert diagnosis.
The ‘check engine’ light came on after the speedometer stopped working
A problem that occurs with digital speed sensors is that they may malfunction and stop sending data to the car’s computer. When the computer tries to calculate road speed it does not receive any information, and as a result the ‘check engine’ light glows.
Replacing the speed sensor will solve this issue, however, if the ‘check engine’ light is not on, and the speedometer behaves erratically or stops working, it is recommended to try the cruise control system in the car, as it uses the same sensors.
If cruise control is working, and the check engine light is on, it may indicate a problem

Car Alternator Problems

Modern cars, trucks and caravans are well-equipped with every comfort one can imagine. All these appliances and the engine need loads of electric power to operate. Where does all this power come from? This requirement is satisfied by a very simple gadget, known as the ‘Alternator’. It is short for ‘Alternating Current Generator’. The efficiency of these devices is around 50 – 60%. Through the use of the alternator, which is a dynamo, your car generates its own electrical power and stores it in a rechargeable car battery. Ergo, it’s absolutely essential that you keep a check on the working of the alternator or you may be left high and dry with no power to drive your car!
How Does the Car Alternator Work?
The alternator creates electricity by exploiting a fundamental law of electromagnetism which is – ‘Changing magnetic field creates an electric field’. There are two important parts of the alternator – stator and the rotor. The rotor is essentially a set of three pairs of electromagnets with opposite poles facing each other, placed on a cylindrical disc. They are 120 degrees out of phase from each other. Stator is the stationary part placed at the center of the rotor disc.The rotor is attached to engine crankshaft, by a belt. Thus, an important part of this assembly is the alternator belt, which transfers engine torque to the rotor. When the engine is operational, crankshaft rotation makes the rotor go around. The revolving rotor creates a changing magnetic field. This field induces a three phase current in the central stator. A current is generated 120 degrees out of phase, by each of the magnet pairs. There are output terminals attached to the stator with separate windings for every phase.However, this output current is AC (Alternating Current) but the car accessories

Wheel Bearing Noise

Detecting the noise in wheel bearings can be a tricky job. However, with the correct understanding of how to diagnose the problem, it becomes easy to solve noise-related issues in wheel bearings. A rumbling or cyclic noise can be heard in wheel bearings with problems in their smooth functioning. If the driver senses even a slight problem in the smooth running of wheels, he should go for wheel bearing noise diagnosis. If the problem of bearing noise is not addressed in a timely manner, it can hamper the functioning of wheels.
Identifying Wheel Bearing Noise
The noise emanating from wheel bearings can differ from wheel to wheel depending on the degree of damage caused to them. At first, the noise originating from wheels might sound like a whistle. However, if the problem worsens, the noise could grow louder. Therefore, it is necessary to find out the exact cause of noise.
▶ A common trick used for identifying problems associated with wheel bears is checking whether noise heard at the time of acceleration and deceleration remains the same. One should drive the vehicle along a circular path, both clockwise and anti-clockwise, in order to find out which of the wheels (left or right) emits the sound caused by a damaged bearing.
▶ The noise originating from a wheel bearing doesn’t change with changing speeds; however, it might increase or decrease at the time of turning. Therefore, one can say that the noise heard at regular intervals, while driving at a steady speed, is a sign of problem associated with bearings.
▶ Do not confuse wheel bearing noise with that produced by a damaged CV joint; both the problems are different from each other and they need be dealt with separately.
▶ Noise produced by wheel bearings is a result of lack of

Tips for Buying a Car Audio Amplifier

If you want to blast the speakers of your car audio system, you will need to install an amplifier. Basically, an amplifier picks up a sound signal from a source and increases it, resulting in the sound getting louder. The difficult part is amplifying the source signal without distorting it. In order to keep them functioning, amplifiers require an adequate power supply and must also have the ability to store sufficient current to be able to deliver all the fluctuations within the music being played.

A CD player or cassette radio produces about 9 real watts at the maximum into 4 speakers considering the power it is provided from the electrical system of the car. However, in case you want more than that to power the speakers you have, you will require an amplifier. Amplifiers provide the extra power resulting in your ability to play music louder. In addition, amplifiers improve the quality of the sound at every level of volume that the music is played in.

In case you are thinking of buying a car audio amplifier, you will require taking into consideration a few factors beforehand. Some of these factors are the power, the channels, and the heat.

The power is one of the most important aspects that has to be taken into consideration when you buy a car audio amplifier. Basically, there are two kinds of power ratings: RMS and Peak.

The RMS rating is a measurement how much power the amplifier will be able to use in order to power the speakers. When buying your car audio amplifier, be careful to choose one to match the ratings of the speakers and subwoofers. If you do not do so, there are high chances of damaging your speakers.

The other type of power rating is the

Car Audio Troubleshooting Tips

Imagine getting a new stereo system installed in your car, but it doesn’t work properly. Car audio problems are common nowadays, the reasons for which can be varied, like loose wires, problem with the amplifier, or problem with the stereo. Such problems can also cause the speakers to produce a popping or crackling sound. However, there are some steps that can be taken to diagnose and repair these problems.

The first thing you would need to do is to find the source of the problem. There can be many things at fault, such as cables, audio amplifier, or speakers. Make sure that everything is properly connected between the speakers, stereo, and the amplifier. Disconnect the wire that connects the stereo and amplifier, but do not unplug the cable connecting the amplifier to the speakers. If the problem still persists, the amplifier might be at fault. But if the problem is solved, simply disconnect the wire from the radio. If the problem still persists, then the connecting cable probably needs a replacement.

The stereo system also won’t work if there is a loose or missing connection. Check all the cables of the stereo, amplifier, and speakers separately and ensure that they are properly connected. Torn, pinched, or exposed cables can also be a reason for the system to be defunct.

If there is not enough power supplied to the speakers, they will not produce sound. Speakers that are installed by the car company work fine with the store-fitted audio system. If different speakers are installed, they might not work due to compatibility issues, or may need more power to operate. Check their power supply by using a power meter. If they are receiving power but are still not working fine, the power provided may not be sufficient.

A blown fuse also can be a reason

Car Speakers Installation

Most cars these days come with an audio system installed. However, many car owners are not satisfied with the factory speakers that come along with the car.

Bluetooth Car Stereo

A car stereo system makes up the audio unit for the vehicle. You can use CD’s or flash drives to play music, or listen to the radio. That’s all it is good for. But Bluetooth being a wireless technology, allows you to connect multiple devices to your car stereo, if it is Bluetooth enabled. Think about it. You are driving to work, you’ve got your favorite track playing, suddenly you get a phone call. Now you have to turn down the music with one hand, and answer the phone with the other. And drive, of course. What if by pressing one button on your stereo system, you pick up the phone, the song’s volume is automatically turned down and instead of through your mobile, the call is played over the stereo? No, this is not a futuristic prototype of a car audio system, this is what a Bluetooth car stereo can do! And with competing brands and technological advancements, this is just the tip of the iceberg, with this type of car audio system.
