2025 Essential Automotive Repair Tools For Repair Shops

Car repair machines and tools are a must for the opening of an auto repair shop, we have to choose the right equipment and tools according to the repair scale of the repair shop, corresponding to the customer, repair brand and other required factors respectively. After selecting the equipment and tools, we can choose the combination of equipment and tools according to the needs of the repair business. Are you confused about how to choose automotive repair tools? This article will recommend the most practical car repair machines for you.

1.Fuel Injector Cleaning:

Injector nozzles typically need cleaning every 10,000-20,000 miles, depending on fuel quality. Carbon deposits can impair fuel injection and atomization, leading to starting issues, unstable idling, increased fuel consumption, and worse tailpipe emissions, especially in winter.

How to select fuel injector cleaning?

  • Cleaning Capacity: It is recommended that the capacity of cleaning liquid is 1000-2000ml, which can accommodate multiple injectors at the same time.
  • Multi-Cylinder Test: It is recommended to select 4-6 cylinders cleaner so that it can be cleaned and compared at the same time.
  • Functions: Including the preparation of forward and reverse ultrasonic cleaning function, leakage inspection test, high-speed spray test, atomisation test function.
  • Test Details: the atomisation test function uses a background light to observe the spray atomisation of the nozzles in a comprehensive and detailed manner to ensure the performance and effectiveness of the nozzles.

2.Automotive Smoke Machine:

When the engine is idling, insufficient boost pressure and other faults. We need to detect the presence of vacuum leaks under the car’s engine. The automotive smoke machine fills the engine intake system with smoke, quickly identifying faults related to intake system leaks, such as loose clamps, pipeline cracks, gasket leaks, and intercooler issues.

  • Built-In Air Pump: all-in-one portable can generate pressure directly in the machine to disperse smoke, external air pumps need to be purchased additionally connected to the air compressor to assist the smoke into the engine.
  • Oil Outlet: easy to recycle the smoke and oil, the secondary use of more environmentally friendly.
  • Pressure Gauge: you can observe whether the machine is pressurised at any time, so that you can quickly identify the use of the machine.
  • Flow Meter Accessories: can adjust the smoke size, increase work efficiency.

3.Borescope Camera

Borescope Camera, applicable to the inside of the cylinder and air-conditioning air supply system and other non-disassembly inspection. Primarily used for inspecting piston and spark plug carbon build-up, the borescope allows direct observation of faults in the cylinder and checks for tiny cracks in the exhaust pipe’s inner wall and welds.

How to select a borescope camera?

  • Snorkel Length: It’s recommended to buy a length of over 1-3 meters; longer lengths allow for deeper access into complex structures.
  • Waterproof Oil Drain Temperature Protection: If the base material can’t adapt to the oil in the engine, wear and tear on your machine will occur rapidly.
  • Probe Steering: It typically supports 210° and 360° camera rotation, facilitating multi-level internal observation.
  • Data Cable Connection/Self-Contained Screen: We recommend users who frequently communicate with customers to use the bracket model borescope. For those who prefer portability, we suggest buying the self-screen model.

 

4.Spark Plug Tester:

The spark plug tester shows the ignition effect and principle, allowing performance testing. You should generally change spark plugs every 20,000 kilometers, but not more than 40,000 kilometers. The common engine speed is between 700 and 3000 rpm. If the customer exceeds this period, we need to check the spark plugs to determine if they need replacement.

  • Multi-hole test: Usually, cars have 4 spark plugs, so if you have the condition, I recommend buying a 5-hole machine directly. This will make the spark plug comparison more intuitive and can speed up work efficiency.
  • Compatible Spark Plugs: Spark plugs on the market are of different lengths. Adjustable tester adapts to a higher degree.
  • Power supply: You can connect a 12V/24V battery, eliminating the need to search for a socket anytime and anywhere.
  • Adjustable RPM: Everyday spark plugs run at 600-1000 revolutions per minute (RPM). In this range, spark plugs ignite efficiently at lower loads, allowing easy observation and measurement of their operating conditions.

5.Refrigerant Analyzer

The Refrigerant Analyzer measures the pressure of the refrigeration system at various stages, helping maintenance personnel assess equipment conditions. It uses a pressure sensor to gauge the refrigerant’s pressure and provide test results.

How to select a Refrigerant Analyzer?

  • Refrigerant Type Supported For Detection: Select a refrigerant type compatible with your refrigerant (e.g., R22, R134a, R410a).
  • Accuracy And Pressure Range Of The Dial: The accuracy of the refrigerant gauge is a key parameter, usually expressed in ±%. The higher the accuracy, the more reliable the measurement results.
  • Pressure Range: The pressure range of the refrigerant gauge should cover the working pressure of the refrigerant. A high-pressure dial should read up to 500 psi, while a low-pressure gauge covers -30 psi to 250 psi.
