It was during the general session meeting on Thursday morning at MACS 2016 Trade Show in Orlando that we first learned about GM’s intention to add several new vehicles to their lineup this year which use HFO-1234yf as an air conditioning refrigerant, and sure enough this summer we’re seeing quite a few on dealer lots. Earlier this month we stopped by at Bergey’s Buick GMC to check out their new R/R/R machine, and also learned more about the redesigned 2017 Acadia, the first GMC vehicle to be filled with the new refrigerant.
“We’ve had the new machine for a few weeks now, but no one’s had to use it yet,” remarked Scott Sowka, service technician at Bergey’s Buick GMC. “The new yf Acadias just arrived this summer, and in fact this one was just built in August!”
GM sources its A/C compressors from various manufacturers, and for the 2017 GMC Acadia they’re using a variable displacement model made by Denso. But there’s something unique on this compressor’s label that we’ve only just begun to see recently, and that’s a smiley face! Sure, we know the guys at Denso are quite helpful and friendly, but we thought there has to be something more to this cheerful icon than just trying to brighten a technician’s day. MACS spoke with Denso’s Brett Grover, one of the technical training specialists at DPAM and an A/C instructor at MACS training events, who explained that this happy image is a requirement specific to GM, which they use to signify compatibility with R-1234yf refrigerant.
In keeping with their sales and service agreement, GM dealers are required to provide certain essential tools and service equipment for their technicians to properly diagnose and service their vehicles. When it comes to these new “yf cars,” one of the required tools is part number GE-50300. If it looks familiar to you, that’s because it’s an unmarked Robinair AC1234-6 machine. It doesn’t directly carry the Robinair brand on the outside, but turn on the power and you’ll see Robinair’s stylized name on several menu screens.
Robinair’s website www.robinair.com has more information about their R-1234yf shop equipment, but you can also see them at the 2017 MACS Training Event & Trade Show, being held February 15-18, 2017 at the Marriott hotel in Anaheim, California. Visit www.macsw.org to get the details!
