Fiat now using R-1234yf in U.S. vehicles


By Steve Schaeber, MACS Technical Editor

It’s been reported by MACS that during 2014, Chrysler Group LLC was the largest car line to use the new refrigerant R-1234yf here in the US market, as it begins the changeover of its vehicle fleet. For the 2015 model year lineup, further developments are coming out of the Auburn Hills, Michigan headquarters. They’ve officially changed their name to FCA US LLC, and their stock ticker is now FCAU, Fiat Chrysler Automobiles N.V. But on the refrigerant front, they’re using “yf” in more cars this year.

The last in the series of “Chrysler Group LLC” labels used by the company, this one is from a 2014 Fiat 500.

At the Philadelphia Auto Show this year, FCA encompassed almost the entire length of the exhibit hall, displaying vehicles from their Fiat, Chrysler, Dodge, Ram, SRT and Jeep brands. By far, they had the most number of vehicles on the show floor charged with R-1234yf refrigerant when compared to other vehicle manufacturers. Although most carry the Chrysler and Jeep emblems, they’ve now added Fiat to that list.

We opened the hoods of many cars, including this two-door 2015 Fiat 500.

The new yf label on this model follows the design pattern being used on other FCA vehicles.

But not all Fiats are charged with the new refrigerant. A survey of several models showed that only the base model Fiat 500 uses yf. The 500L, which is a longer, 4-door model, is still charged with R-134a.

While still in use on some models today, this Italian version is Fiat’s older R-134a label, pictured here on a 2015 500L. The proper refrigerant charge amount (measured in kilograms) is indicated by the hole punch above 0,450.
