New England Institute of Technology Diagnostic Training – Here and Abroad!
Written by Christopher Bannister, Automotive Professor and Chair
Summer is here and it’s the time of year when everyone thinks more about a vehicle’s air conditioning system. Especially when you are trying to get it to blow some cooler air on those 90 degree days!! When we started our summer quarter in July, by the third day of classes I already had requests from two students to diagnosis problems with their AC systems.
Air conditioning refrigerant is changing, again, with the 2013 model year. In 1987, the U.S. and 180 other nations signed the Montreal Protocol which eliminated the use of R-12, Freon as we knew it, as a refrigerant for vehicle AC systems. Many of us went through a period of conversions in the early 90’s to HFC134a. Well, times are changing again! In March of 2011 the EPA announced the approval of HFO-1234yf for use in most car AC systems for the future. GM has stated that it will be using HFO-1234yf in some 2013 models and within the next few years this new refrigerant will become the standard for the automotive industry.
To get prepared for this change, New England Tech sent one of its instructors, Robert Kennedy, to the Mobile Air Conditioning Societies (MACS) training center in Pennsylvania. Bob spent a week studying refrigerant recovery, recycling, recharging, leak detection and diagnosis. While he was there, Bob took an additional class to become a MACS certified trainer.
Armed with this new knowledge, Bob traveled to the US Army base in Spangdahlem, Germany to provide diagnostic training for the armed services. Bob was able to provide two days of training on pressure and temperature diagnosis, electronic and UV leak detection and the precautions to take when working with this new refrigerant. This is the same instruction provided to New England Tech students as part of their technician training. Of course you cannot have a discussion about diagnosis of the AC system without touching on climate controls and the various sensors and switches within the system. This discussion led to an additional two days of training on multimeters and electrical testing. Bob is also a certified Snap-on instructor and was able to provide the Army with some Snap-on multimeters as well as certification on meter usage. Again, the same instruction provided to New England Tech students during their technician training.
