Top 6 Things To Know About Car Repair

Before you go to the garage to have your car repaired, make sure you know the most common mechanic scams to watch out for. This will help you avoid paying unnecessarily for a service your car doesn’t really need. So, without further ado, let’s dive into this blog and learn some of the things everyone ought to know about car repair.

1. Car repairs: flushing the engine

Many people use their cars without knowing what's really under the hood. When you break down, you rush to the garage. However, a little knowledge about the various essential mechanical parts of the car can save you the cost of repairing it since you can do it yourself. Here is a lexicon of car parts that you absolutely must know. The engine It is the main part of a car. Without it, the vehicle cannot function since it guarantees its propulsion and its starting thanks to the energy it produces. Its operation is similar to that of an air pump. The engine has cylinders, each containing a piston. It is activated in four stages: • In the first stage, the pistons descend, sucking in fuel and air ; • Then they move up so that the cylinders can compress the fuel-air mixture; • An explosion due to the combustion of the mixture then occurs, causing a spark. This reaction sends the pistons back down. • Finally, the pistons will move up again to let the exhaust gases pass out of the engine. The cycle will start again from the beginning. The back and forth movement allow the engine axle to turn and move towards the wheels. This is how the car starts. The air filter Rectangular or circular in shape, the air filter is your car's lungs. It prevents dust from entering the engine. Indeed, if the air circulating in the engine is dirty or in small quantities, the fuel cannot be burned. It is, therefore, necessary to regularly check the condition of your air filter. The injection system This is where the fuel is sent to the cylinders. The injectors spray the gasoline or diesel into the cylinders and mixed with air. The cylinders All the cylinders of an engine are grouped in what is called displacement. Generally, the most common engines have 4, 6, or 8 cylinders. The role of the cylinders is to guide the pistons during the engine's movements. When they slide, the cylinders offer as little resistance as possible. They also ensure that the gases inside the engine are sealed. The valve Composed of a stem with a head, a tail, and a collar, the valve is an essential part of the operation of an engine. When it is activated, all the valves start moving. They seal the combustion chamber when the air-fuel mixture explodes in the closed position. They allow the gases produced during this explosion to be evacuated in the open position. The transmission Automatic or manual, the transmission allows the change of speed, the reversal, or the static position. It is responsible for the transfer of energy from the engine to the wheels. The exhaust system These are pipes that are used to expel the gases produced by combustion to the outside. The exhaust system has two components: • The catalyst or catalytic converter: a device for controlling gas emissions. Its role is essential in reducing pollution. • The muffler: As its name suggests, this is a mechanism that reduces the noise of exhaust gases. It contains a perforated tube called a "machine gun tube" covered with rock wool that acts as an insulator. Its baffle arrangement ensures the slowing down of the exhaust speed and, therefore, the noise. The battery The battery is an essential part of the car's operation, storing energy from the alternator and releasing it. Its main role is to launch the engine when starting. In addition, it powers all the electrical and electronic accessories used by the car: car radio, ABS, headlights, air conditioning, power windows, etc. The alternator belt or accessory belt It provides the electricity needed to keep everything running. As soon as the engine is started, the alternator is also activated. Like an energy generator, it recharges the battery for the next start. The parts mentioned are all essential to the proper functioning of a car. They require regular inspection and maintenance. If one of them fails, it must be replaced immediately.

Visits to the mechanic are rarely pleasant. First, because repairs are often expensive; secondly, during an inspection, the mechanic may point out many mechanical flaws due to inadequate maintenance of your car, he may suggest. But don’t take each of these recommendations as absolute truths. Some investments suggested by a mechanic are actually unnecessary.

Here is the first example of a common suggestion made by a mechanic: flushing the engine. Don’t be fooled: don’t agree to an engine flush unless you’ve been driving your car for several years and you’ve noticed a buildup of greasy material under your car’s oil cap. If a mechanic tells you that he has to flush your engine because your oil is dirty, he is lying.

2. Cleaning the injectors

Fuel injectors should be cleaned, but only if they have a lot of miles on them (i.e., 100,000 or more). If the mechanic tells you that the injectors on your car with 20,000 km are filthy, don’t believe him. However, if you do suspect that there may be a problem with your fuel injectors, as a precautionary measure, add an injector cleaner to your fuel tank on your next fill-up. Otherwise, if you buy good quality gasoline and your car is fairly new, you probably don’t need to clean your injectors.

3. Fuel-saving devices


It’s unfortunate, but the devices your mechanic tries to sell you to save gas don’t work. Period. To save gas, accelerate gradually, avoid unnecessary braking, empty the trunk of your car of unnecessary things and learn to drive efficiently.

4. A surprise repair without your consent

The classic scam: the notorious repair without your consent. You leave the vehicle for an oil change or a minor repair, and your mechanic tells you on the way home that there were life-or-death repairs to be done on a vehicle that seemed to be doing fine. As with the initial quote, it is possible to sign a “repair contract” once the order is placed. Signed in duplicate and stating that you do not want any repairs other than those requested, this agreement acts as a legal contract.

5. Always have something to fix

Believe it or not, your vehicle may be fine. There are also mechanics who will tell you that “everything is fine” after an inspection. But if your mechanic consistently finds “something wrong” with every inspection or visit, you’re not the unluckiest person in the world. It’s probably a deliberate move on his part.

6. Repairs that are not guaranteed

According to the law, “any repair done on an automobile is guaranteed: it is a legal guarantee. It lasts for 3 months or 5,000 kilometers, whichever comes first. It includes parts, labour, and reasonable towing costs. The warranty begins when the vehicle is delivered to the consumer.” the legal warranty does not cover this work:

  • A repair with a total cost, including parts and labor, of no more than $50
  • The sale and installation, billed at the same time, of tires
  • The sale and installation, billed at the same time, of a battery.

That said, a good mechanic will not hesitate to offer you a warranty in addition to the legal warranty he is required to offer on the repairs he has just made.
