Tires! What to know about them
When you go out on the road, remind yourself that the only object touching the ground are the tires.
Tires are an exceptional part and play an important role in a car. Whether you drive a 4X4, a sedan or a family car, your safety matters and never overlook the following signs of troubled and promematic tires. Taking good care of your tires leads to correct consuming of fuel which in the long run, equals to money saving. Everybody likes that!
What is tire rotation and do all cars need it
What this means is that each tire should be changed diagonally; meaning that rear left tire should be moved to the right front side of the car (passenger side), and the rear right side should be moved to the front left side of the car (driver side). This 'rotation' of the tires will help the tires wear evenly on all four sides. This saves money and helps extend the life time of the tires.
Why buy four tires and alignment
It is often recommended by car dealers to change all tires at the same time simply because you have control and accurate information in terms of dates on when your tires will need to be changed and also, it helps the wheel alingment technician to track your car as accurately as possible. Remember, one flat tire or low inflated tire can make your car pull to one of the sides, either to the right or to the left, depending on the side of the car the tire is located.
How can I know what psi of air pressure to put into my tires
Simple! You can find this information on a white sticker located on the driver side of the car. The sticker contains the correct size of tire for the car, the correct pressure for the front and rear tires, as well as information for the spare tire. Remember, always check the pressure on all tires, especially the spare one as people tend to forget that store unused tires usually lose air very fast.
Common wearing problems:
Having a bad suspension can lead to bad wearing in your tires, this can be on the right or left shoulder causing the wires to come out of the rubber casing. This can be a sign that your car is in need of new shack absorbers, fixing of wheel alingment, upper control arms or lower, ball joints whether upper or lower, also stabalizer links and/or sway bar bushings.
Tires in the winter and summer seasons
It is recommended that you change your tires to winter tires for the winter as it's a special tire with grooves all over the tire to secure a better grip on the road while driving, this helps avoid slides and skids.
What is a flat tire
A flat tire is basically a regular tire that has lost air through an opening. This lost of air can be caused by a puncutre on the rounded rubber or on the sidewalls of the tire. Tires sometimes leak air through the aluminium or steel wheels as sand and other hard substances can get in causing the tire to deflate. Also, as times passes by, valves and stems tend to dry up and in time become loose, this also makes the tire leak air. It is very important that valves and stems are changed when you change the tires as this avoids future problems.
Is it safe to buy secondhand tires
There are quite a few secondhand tires still in the market are in perfect conditions and can be driven a few more miles, however, it is not recommended to buy secondhand tires as you don't really know in what condition is the tire until you drive the car in them. Our experience tells us that 5 out of 7 tires have irregularities and abnormal wearing. This can cause your car to pull even if the wheel alingment is perfect state. Other problems that may rise are: punctures on the sidewalls (this makes the tire 30% safe out of a 100%) which in some cases are unrepairable, and buldges on the sides. Buldges tend to burst in a matter of days. We suggest that YOU DON'T PLAY WITH YOUR SAFETY!
Engine & Oil Change
Auto dealers suggest changing the oil on your car every three thousand miles, or every three months, whichever comes first.This allows the engine to always run smoothly whilst taking longer to get broken. Changing the oil as indicated is not only beneficial to your car, but also saves you money in the long run.
Which oil to use on your car
There are a large variety of oil brands to choose from, and choosing takes time and dedication. First thing you must know before changing the oil is which is best for your car. It is not an easy decision in fact, sometimes is better to just leave it to your mechanic as he would know best what oil he must use. One of the three major things that your mechanic will look into before changing the oil is your CURRENT MILEAGE, the make, model and in some cases the year the car was built.
Here are the the different types of oils available in the market:
5WX10 - for new vehicles with very low mileage. These vehicles are usually brand new vehicles; 0 miles.
5WX20 - for new vehicles with low mileage, usually within the 20, 000 or 30,000 miles.
10WX40 - most commonly used oil for vehicles within 70,000 miles to 130,000 miles. This is a thicker oil.
20WX50 - a more thicker oil used on vehicles with over 130,000 miles.
Brands that we recommend: Castrol (economic cars), Mobile (for sports and luxury cars),
As you may be well aware this is the cheapest oil change you can have in the market. Some shops would use and sell recycled oil, and although this is not against the law, the use of recycled oil is allowed and saleable, however, most cars are now built with the highest technology and filled with sensors that recycled oil is no longer recommended. It may cause your engine to stop running adequately and can lead to more serious problems causing you to spend unnecessary money.
What is an alternator and how does it affect your car when it gets damaged
An alternator is the generator of energy in the car, enery which is stored in the battery and later used by the car when needed in order to keep the system active and running. If the alternator brakes down, the car will use all the energy stored in the battery but it won't be able to get more generated energy from the battery since the alternator cannot generate, therefore the battery gets drained. The car will come to a full stop once it runs out of stored energy.
When this problem occurs, one thing will happen on the dashboard of your car; it will light up the battery light. Indicating that there's something wrong in the system, however, it does not necessarily mean that the battery has damaged, but that the system in the battery needs to be checked as an anomally has been registered by the computer of the car.
What is a Starter-Motor and what is its function in the car
It's a small motor, so small that it usually fits in your hand and it's installed in the side of the engine. This motor is in charge of spinning the flywheel (a heavy disk rotating on a shaft) of the car to make it start, and its activated by the driver turning the ignition switch to the 'on' position. This controlled energy make the bendix drive on the starter to be pushed out on to the flywheel and spin, this movement makes the engine start.
What happens when the starer brakes down?
If the starter brakes down, you won't be able to start your car. The good news is that before the starter dies on you, it will start by giving you signals that its becoming to its end by giving you a lot of problems when trying to start the car. Its a device that usually takes time to die completely, therefore you will have time to change it even before it brakes completely.
Cars now-a-days are built with the latest technology, therefore computers, sensors and wires are much part of it than back in the 1930s.
This is why when you go to your local mechanic, the first thing they check is the dashboard, this will tell the technician if the engine has detected a trouble code which is the definition of symptoms or side effects of sickness. This much relates to humans and how the brain and body react to internal changes.
When the technician connects the OBD Code Reader or Scanner, this is what he/she will see in the display monitor. For example, the P0420 code is followed by the description O2 sensor.
There are two sensors in the car of this kind: Upstream Oxygen Sensor, and Downstream Oxygen Sensor. This types of scanners help technicians diagnose the problem accurately or at least 90% accurately.
Diagnosing a car efficiently helps technicians avoid buying extra parts or complicating the problem even more. This is a very typical problem that most mechcanics or technicians face. They begin working on the car and when it becomes complicated to diagnose, they turn to other mechanics to solve the problem.
Hightech recommends cars to be scanned using Snap-On OBD Scanners as they are very reliable in the market and mostly accurate.
