Top Diagnostic Tools Used in Auto Inspections

Owning a car can be expensive, especially if costly repairs have to be conducted on your vehicle. In the USA, the average car owner is believed to spend nearly $800 a month on their vehicles  according to the American Automobile Association.

This includes routine maintenance, fuel, and insurance. The automotive industry has become increasingly tech-centric in recent years with everything from routine maintenance to repairs undergoing a notable metamorphosis.

Years ago, car technicians may have been required to strip a car completely in order to diagnose a fairly simple fault. Today, however, there are a number of very nifty tools, such as the following, that is transforming the way we inspect our vehicles forever.

Borescopes offer a close-up view

While some parts of a car are easy to visualize and reach  during routine vehicle maintenance and repairs, others are far trickier. Flexible borescopes make it significantly easier to examine hard-to-reach places such as the pistons and piston rings, valves, and fuel lines of the car.

Not only does the use of a borescope reduce the need to disassemble the entire engine but it also shows the various parts in real-time video. Expert technicians at  https://spiborescopes.com/ believe that a quality borescope that sports an excellent camera and large screen is a worthy investment for both operators in the automotive industry as well as car enthusiasts. Apart from being used in diagnostics, automotive borescopes are also utilised during the production process.


Tire pressure gauges can boost performance and safety

Although the electronic components on a vehicle are of great importance there are other parts that also need to be checked on a regular basis. A car’s tires are the only part of the vehicle that comes into direct contact with the road and should therefore always be in an optimal condition.

Among the most important things to check on a tire, is whether it is properly inflated. Tires that are poorly inflated are as dangerous as tired that are damaged or without sufficient tread.

Despite it being easy to spot a tire that is fully deflated, it is a much harder task to gauge whether all tires are inflated to the correct pounds per square inch (PSI) value. If the PSI is too high, even the smallest defect or obstacle in the road can cause the tire to pop.

If the PSI is too low, however, the tire will be significantly weaker. Three types of tires pressure gauges exist stick, dial, and digital.  Although dial gauges are both hardy and accurate, those with an LCD display are significantly easier to read.


OBD-II scanners are making diagnostics easier than before

It is often very difficult to diagnose exactly what is wrong with a car that isn’t running effectively. This is particularly true for vehicles that sport electronic fuel injection systems.

Even when it is possible to replicate the issue it can be very hard to differentiate between certain chips and sensors. Onboard diagnostics 2 (OBD-II) is a very useful protocol that is able to expose these problems within a car by making use of a diagnostic scanner. The  majority of modern-day vehicles are equipped with an output socket for the OBD scanner to be connected to.

The OBD-II provides access to information and diagnostic trouble codes for the engine and transmission as well as emission control systems. Furthermore, an OBD-II also makes it possible to access vehicle information such as the ignition counter, vehicle identification number, and calibration identification number.


Circuit-and multimeters continue to serve a purpose

Modern-day vehicles possess a complex network of circuitry which can be affected by a range of faults including those triggered by water damage. At times, these faults can be difficult to spot with the naked eye, making it necessary to make use of a variety of tools such as circuit- and multimeters to aid in diagnostics.

Although the technology utilized by these tools has not changed exponentially in recent years, they remain important components of a diagnostics setup.

They can expertly measure a range of variables including electric current, electrical resistance, and voltage in order to pinpoint the area in which the fault lies. Apart from locating missing cylinders, a top-end circuit tester can also measure high-frequency ignition pulses that allow for the calculation of the engine’s rotational speed.


Infrared thermometers aren’t only for medical use

In order for a car to operate effectively, all components that need to be cooled must be cooled correctly. Thermal sensors, which are used to measure the temperature of the engine’s coolant, also need to be checked from time to time to ensure that they are working properly.  These handy implements are typically equipped with a laser for easy pointing purposes.

They can be used to troubleshoot and diagnose a range of faults while also allowing for effectual spot checks on various components including the radiator, brakes, engine timing, and HVAC system.

An infrared thermometer can even be used to check the temperature of a turbocharge exhaust housing, accurately providing information about both the cooling and lubrication properties of a variety of compounds.


Battery testers are of great importance

Vehicle battery testers may not be the most hi-tech diagnostic tools in use, but they do serve a very important purpose. While vehicle technicians undoubtedly have to be in possession of a quality battery tester, private vehicle owners can also benefit from being able to test their own batteries.

There is a range of both analog and digital battery testers available, each sporting both advantages and disadvantages. Top-of-the-range vehicle battery testers are designed to test both the load and the condition of a variety of batteries along with its starter motor draw. A quality battery tester is often simple to use but possesses the latest technology that will enable it to deliver accurate readings which, in turn, can lead to swift diagnoses.


Car diagnostics have evolved considerably in recent years with both tools and procedures becoming increasingly streamlined and effective. Thanks to continuous technological innovation, car maintenance, and repairs will become even less invasive in the near future.
