Best recommended practices of AC Service with Bob Pattengale

A/C Best Recommended Practices with Bob Pattengale


Automotive Video presents a brand new training program on air conditioning fundamentals with Bosch Field Sales Technical Trainer Bob Pattengale.

Today, virtually every car has air conditioning, and virtually every car is going to need to have that air conditioning serviced from time to time. In this 75 minute training program, Bob focuses on the best recommended practices: the steps that you need to take long before you hook up an air conditioning machine. Are the belts in good condition? Are there any leaks in the system? Is the heater valve stuck open? Do you have a dirty cabin air filter?

This program is intended to cover the fundamentals of what makes the A/C system work on newer vehicles and the best recommended procedures for diagnosis and repair. Bob will help you avoid the common, costly mistakes that affect your bottom line. He will cover things like identifying refrigerants, recharging the system, replacing components and purging air from the system. Also learn about the new J-2788 standard, approved refrigerants and repair procedure regulations.

  • Initial system examination
  • Performance Testing
  • Attaching Temperature Probes
  • Refrigerant Blends
  • Monitoring Pressure
  • Analyzing Readings
  • Case Study on Pontiac G6
  • Charging System
  • System Review
  • Top 11 A/C System Repair Mistakes per MACS Surveys

Join Bob and AVI as we focus on how to get the job done right every time with some great best practices you can easily follow

Why J2788 with Bob Pattengale

Why J2788 Standard with Bob Pattengale


What if you could save 30 minutes each day in the shop? Do you have some areas in the shop where you might be wasting a little bit of time? You might have a machine that’s not quite up to its 100% potential? This DVD shows you why J2788 makes a difference!

J2788 air conditioning machines came onto the market about three years ago. If you purchased one in the last three years, chances are you purchased a J2788 machine. But what are the differences? Bob Pattengale talks about them in this video.

J2788, the new standard, is based on research that was done with the Society of Automotive Engineers and the Mobile Air Climate Systems Association (MACS) working in conjunction with car manufacturers.

Mastering Hybrid HVAC Systems with Dave Hobbs

Mastering Hybrid HVAC Systems with Dave Hobbs


In this program, Instructor Dave Hobbs teaches you hands-on fundamentals to servicing Hybrid A/C systems. Advance your diagnostic strategies by understanding these complex systems through live on car demonstrations. Dave covers essential hybrid A/C technical tips and tricks on how to keep not only your customers cool but the hybrid battery from overheating.

In depth instruction and hands on training on:

  • Hybrid Safety and the Service Switch
  • Electric AC compressor
  • Diagnosing coolant sensor DTC’S
  • Evacuating and recharging the hybrid A/C system
  • Hybrid Emissions solutions
  • TIS to Web for Hybrid applications

Hybrids are 95% the same as a traditional vehicle, however diagnosing that 5% difference can be difficult without knowing important hybrid scanner data PID information. Dave introduces you to these hybrid data pids like evaporator fin thermistor, solar sensor, engine coolant temp sensor, air mix servo pulse, electric heater current, and compressor speed using Toyota’s factory scan tool, the Tech Stream to help you understand good vs bad data readings.

Dave also discusses safety tips when evacuating and recharging the A/C system, informing us about the importance of using a J2788 compliant recovery machine to stabilize critical charge systems and demonstrates how to remove harmful PAG oil from the recovery machine and it’s hoses to avoid contamination.
