Applying Mechanical Inspection Tools To Ignition Drivability Issues

Watch: OBD Zero Diagnostics in an OBDII World

Follow along as we discuss the latest OBDII engine management systems. Sponsored by Summit Racing Equipment.

The basics of diagnostics are often ignored in favor of scan tools. But, it is the basics of fuel, ignition and compression that are at the heart of many sophisticated tools that connect to the OBDII connector. In this livestream event, we looked at how core diagnostic tests apply on a small-block Chevy and the latest OBDII engine management systems.

  • Basic health check of the engine using compression and leak-down tests.
  • Build on the wiring discussion by installing an ignition box.
  • Show how to install and set the distributor.
  • Use the timing light to set it up the distributor. 
  • Show advance movement with a timing light.
  • Show dwell and engine RPM measurement.
  • Cover voltage to the coil and discuss the primary and secondary winding.
  • Show a waveform of the new ignition box.

Choosing the Right Power Steering Fluid

Learn what power steering fluid is, why it’s crucial for your customers vehicle, and how to choose the right type.

So what is power steering fluid? Power steering fluid is hydraulic oil for the most part, with certain additives that are tuned for the automotive applications, but it is hydraulic fluid. In other words, you have a pump that creates pressure and that force is changed into energy at a steering rack by turning the wheels or extending the tie rods in either direction. What else is hydraulic on the vehicle? The automatic transmission. This is why some vehicles will actually specify transmission fluid to be used inside the power steering system, but there are exceptions. Certain vehicles out there, mostly Asian, have their own formulation of power steering fluid. So it is absolutely critical that you match the power steering fluid with the application. Some may use a different weight of oil, and if you use the wrong power steering fluid, it can change the feel of the steering, but most of all, it can damage the pump and the rack on the vehicle.
