Recommendations before Repairing Your Car
Before you start repairing your car on your own and before downloading your manual, we want to provide you with all this information such as advice, recommendations and suggestions that you should keep in mind, we know that this manual will help you, but it is important that you know some points important before you get your hands on your own car.
The best way to avoid car repair scams is to be prepared. A good starting point is knowing how your vehicle works and knowing how to identify the most common car problems.
It is also important to know how to select a good technician or mechanic. Knowing this type of information about your car can help you avoid technical errors.
Basic Information about Car Repairs
How you should choose a Mechanical workshop
What should you consider when choosing an Automotive repair shop?
- Ask friends, family, and other trusted people for recommendations. To avoid a hasty decision, find a repair shop before the need arises when your car breaks down.
- Find out by phone and compare options to get the most convenient deal, and also compare the policies applicable to the warranty for repairs made to your car.
- If state or local laws have any registration or licensing requirements for repair shops, ask for them and see if they are up to date.
- Make sure the repair shop meets your vehicle warranty requirements.
How to Choose a Good Mechanic
Is there a Mechanic better than another?
Look for workshops that display various certifications – for example, a seal of excellence from Automotive Service Excellence (in English). Certification indicates that some or all repair shop technicians meet basic standards of knowledge and competency in specific technical areas. Make sure certifications are current, but remember that certification alone is no guarantee of honest, well-done work.
Ask if the technician or shop has experience repairing vehicles of the same make or model as your car.
Car repair costs
How to solve the mystery of how much to pay to repair your car
Before authorizing a repair job, ask the shop how they calculate prices. Some shops charge a flat rate for car repair labor. This published rate is based on an estimate – independent or from the manufacturer – of the time it will take to make repairs. Other shops charge fees based on the actual time it took the technician to make the repair.
If your vehicle needs complicated or expensive repairs or if you have questions about the work you are recommended to do, consider getting a second opinion.
Find out if you will be charged a diagnostic fee if you decide to have the repair work done at another shop. Many repair shops charge a fee for the time it takes to diagnose.
Repair shops that only do diagnostic work and do not sell parts or repairs can give you an objective opinion on the necessary repairs.
If you decide to do the repair work, ask for a written estimate.
What things should a written budget include?
The budget must identify the problem or damage to be repaired, the necessary parts and the expected charge for labor. Ask to be given a signed copy of the budget.
You should also mention that the shop will contact you for your approval before beginning any work that exceeds the specified amount of money or time period.
Know the spare parts to Repair the Car
The parts or spare parts are classified as follows:
- New – Typically, these parts are manufactured according to the original manufacturer's specifications, either by the vehicle manufacturer or by an independent company. The prices and quality of these parts are variable.
- Remanufactured, rebuilt and reconditioned – These terms generally mean the same thing: they are parts that have been refurbished and are in good working order. Many manufacturers offer a warranty that covers replacement parts, but does not cover the cost of labor to install them.
- Used or second hand – These are used parts from other vehicles and have not been altered. In some cases, used or second-hand parts may be the only resource to replace a failed part, but their reliability is rarely guaranteed.
What to do when the car repair is finished?
Ask for a complete repair order that describes the work performed. The order must list all repairs made, the parts installed by the shop, the cost of each part, labor charges and the number of kilometers indicated by the Odometer when you took the vehicle to the shop and when it was completed the repair work. Ask to be shown or given all replaced parts.
Car Preventive Mileage Maintenance Table
What are the consequences of not maintaining my car?
There are several parts of your vehicle that are interrelated. Skipping maintenance can lead to problems: specific parts – or an entire system – could fail. Neglecting the simplest maintenance routine, such as changing the oil or checking the coolant, can lead to poor fuel economy, unreliable handling, or costly breakdowns. It may also void your warranty.
What steps should I take to avoid costly repairs?
Follow the maintenance program proposed by the manufacturer according to the use you give your vehicle and detailed in the owner's manual of your car. Some repair shops have their own maintenance schedules that require more service visits than manufacturers recommend. Compare the workshops' maintenance programs with that in your manual. Ask the shop for explanations – and make sure you understand them – to clarify why they recommend doing more services than those recommended by the car manufacturer.
How to protect your investment in your car repair
Warranty
There are no “standard warranties” for car repairs. Make sure you understand what is covered by your warranty and ask for it to be put in writing.
You should be aware that warranties may be subject to limitations, including factors such as time, mileage, deductibles, dealers authorized to perform work under warranty, or special procedures required to collect refunds.
Auto Service Contracts
Many vehicle dealers and other dealers sell optional contracts – service contracts – operated by vehicle manufacturers or independent companies. Not all service contracts are the same; Prices vary and are usually negotiable. To decide which service contract is best for you or not, consider the following:
- Its cost.
- Repairs covered.
- If the contract coverage overlaps with the coverage offered by another warranty.
- The deductible.
- Where the repairs will be made.
- The procedures required to file a claim, such as prior authorization for specific repairs or compliance with vehicle maintenance schedules.
- If the company pays the repair costs directly to the mechanic shop or if you must pay first and then process a refund.
- The reputation of the company offering the service contract.
How to prevent failures in your car
The more you know about your vehicle the more likely you are to prevent repair problems. You can detect many of the most common problems using your senses: observing the area around your vehicle, listening for strange noises, feeling changes when you drive your vehicle, or even noticing unusual smells.
Diagnose Fault by observing the Car
The appearance of small spots or an occasional fluid drip underneath your vehicle may not mean much. But more widespread liquid or fluid stains deserve attention; Control the composition of the drip immediately.
You can identify fluids by their color and consistency.
Yellowish-green, light blue, or phosphorescent orange spots indicate a engine overheating or a leak antifreeze liquid produced by a damaged hose, due to the water pump or a leak in the radiator.
A stain of dark brown or black oily fluid means that the engine is leaking oil. The leak may be due to a damaged gasket or sealant.
A red oily stain indicates a transmission fluid leak, of the servo steering or power steering.
A clear puddle of water usually does not indicate a problem. It may be due to normal condensation from your vehicle's air conditioning.
Learn to Find Vehicle Faults by Smell
You can discover some problems with your nose by detecting them by its smell:
- The smell of burnt toast – a mild but pungent odor – usually indicates an electrical short circuit and burned insulating material. For added safety, try not to drive the vehicle until the problem is diagnosed.
- The smell of rotten eggs – a persistent burning sulfur odor – usually indicates a problem in the catalytic converter or transformer or other emissions control devices. Do not delay in making the diagnosis and repair.
- A thick sour smell, usually means burnt oil. Look for signs of oil loss.
- The smell of gasoline After a failed start it may mean that the engine is “choked” with fuel. Wait a few minutes before trying to boot again. If the odor persists, there may be a leak in the fuel system – a potentially dangerous problem that needs immediate attention.
- A smell of burnt resin or an acidic chemical odor may indicate overheating of the brakes or clutch. Control the handbrake. For. Wait for the brakes to cool before repeating sudden braking on mountainous roads. If there is a little smoke coming out of the wheels, it means that the brake is stuck. In this case, the vehicle must be towed for repair.
- A sweet smell indicates a loss of cooling fluid. If the temperature gauge or warning light does not indicate overheating, drive carefully to the nearest gas station and monitor its temperature gauges. If another metallic smell is added to this smell and you see some smoke or steam under the hood, it means that the engine is overheating. Stop immediately. If you continue driving in these conditions you could severely damage the engine. You would have to haul the vehicle with a tow truck to repair it.
Detect Car Faults through sound
Squeaks, squeals, rattles, roars and other types of sounds provide good clues to identifying problems and maintenance needs. These are the most common noises and their meanings.
- Screech – A high-pitched sound or hum, usually related to engine speed, may indicate: Loose or worn steering, ventilation or air conditioning belt.
- Snap - A slight high-pitched noise related to engine or vehicle speed may indicate: Loose wheel cup or rim. Fan blade loose or bent inwards. Starter valve blocked or low oil level in the engine.
- Squeak – A high-pitched, throbbing metallic sound that generally occurs when the vehicle is moving: It may be caused by brake wear indicators alerting you that it is time for maintenance service.
- Roar – A low rhythmic sound may indicate: Defective exhaust pipe, transformer or shock absorber. Wear on the cardan joint or other driveline or steering component.
- Metalic sound - A high-pitched metallic knocking sound related to engine speed: Usually caused by using lower octane gasoline than recommended. Consult your car's manual to find out the correct octane rating. If the problem persists, the engine ignition regulation may be failing.
- Strong hammering – A rhythmic hammering sound may be caused by: Worn crankshaft or shifting tie rod or connecting rod. Loose or detached transmission torque converter.
- Hit off – An occasional knocking or hammering may indicate: Loose shock absorber or other loose suspension component. Loose muffler or exhaust pipe.
Check Failures When Driving the Car
You may notice some symptoms while driving your car, you may notice an uneven ride, vibration, and poor performance. These symptoms almost always indicate a problem.
Management Problems
- Misaligned front wheels and/or wear of the steering components, for example, the drive gear or wheel or the joint joint can cause steering deviation or difficulty keeping the vehicle in a straight line.
- Deviation – the vehicle's tendency to drift to the right or left – can be caused by something as routine as underinflated wheels or tires or by something as serious as a front axle failure or front misalignment.
Ride and handling
- Shock absorber wear or other suspension components – or improper tire or tire inflation – can result in poor cornering ability. While there is no set formula for replacing shock absorbers, try this: bounce the vehicle hard up and down on each wheel and then let it bounce on its own. Check how many times the vehicle bounces. If the shock absorbers are worn the vehicle will bounce only once or twice.
- Generally, elastics or springs of a vehicle do not wear out and there is no need to replace them unless one of the angles of the vehicle is lower than the rest. If you overload your vehicle, the suspension can be damaged.
- Correctly balance the wheels or tires. An unbalanced or improperly balanced tire causes vehicle vibration and can prematurely wear steering and suspension components.
Truck Brake Repair
Brake problems have several symptoms. Schedule a diagnosis and repair if:
- When you apply the brake, the vehicle pulls to one side.
- The brake pedal stays stuck to the floor when you maintain pressure on the pedal.
- You hear or feel a rubbing or grinding noise during braking.
- The “brake” indicator light on the instrument panel comes on.
Motor
The following symptoms indicate an engine problem. Diagnose your vehicle and schedule the repair,
- Engine starting or ignition problems.
- The “check engine” indicator light on the instrument panel comes on.
- It jams abruptly or turns off.
- Poor or insufficient acceleration.
- Low fuel efficiency.
- Excessive oil consumption (more than a quart of oil between changes).
- The engine continues to run after removing the ignition key.
Transmission:
If your car's transmission malfunctions, it may be due to a defective component or simply a disconnected hose or a clogged filter. Make sure the technician checks the simplest things first; Transmission repairs are generally expensive. Some of the most common symptoms of transmission problems are:
- Abrupt or hard shifting between gear changes or speeds.
- Delay or lack of response when changing from “neutral” to “drive” or “reverse”.
- Failure to shift during normal acceleration.
- False acceleration. The engine revs but the vehicle does not respond.
How to fix my car problems
When your car has a problem it doesn't always mean that you will have to do a big repair. Let's look at some of the most common causes of problems and techniques to help you and your mechanic detect and repair them:
- Alternator – If the alternator wires are loose or detached, it may appear that your car's alternator is faulty. Before replacing the alternator the technician should check for loose connections and perform a test.
- Drums - If the battery terminals or posts are corroded or loose, it may appear that your car battery is dead or damaged. Before replacing the battery, the technician should clean the terminals and perform a functional test.
- Start - What appears to be a faulty starter or ignition may actually be due to a dead or improperly connected battery. Before repairing the starter, ask the mechanic to check all connections and test the battery.
- Silencer – A loud roaring noise under your vehicle indicates that a new muffler or exhaust pipe needs to be installed.
- Tuning – Chances are good old “tune up” isn't relevant to your vehicle. Most modern vehicles have few parts that need replacing, except for belts, spark plugs, hoses and filters. To do this, follow the recommendations detailed in your car's manual.
