Air in car didn't seem real cold today so thought I would have friend check charge .
Now as he is a pipe fitter / air conditioning specialty - thought it would be easy . NOPE 134A gauge setup wont fit onto 2017 or newer vehicles - only thing mine is 2015 but evidently some vehicles switched before mandated . So I now need to find adapters for gauge set , find some R1234yf gas, and or have dealer charge system . Evidently reading some sites the cost for dealer is beyond first born and gold bars . So now to figure next step besides driving with window down . |

I've never worked with the latest refrigerants but our new Subaru Forrester uses this. Casual glance and I thought the charge port was R-134A by look. I only seen the one fitting with a black cap and don't know if suction or discharge side. The compressor stated R-1234YF refrigerant and I'll have to delve further into this.

Pressures are nearly a Third HIGHER that R12 to 134A, then add another 1/4 to this new stuff. Gauge set I witnessed High Side high end gauge potential was 600#

I'll look online for a P-T and enthalpy charts to see if any better performance than former refrigerants.

The fittings are a different size than 134 fittings and like those both high and low side are a different size . I see one can buy adapters to convert gauge set over for around $12 per fitting , but also a warning before use gauges should be purged to prevent contamination of system .
1234YF I see is around $45 to $65 for 8oz can and system holds 1.8 pounds , Was looking up some places and says $250 to $400 to diagnose problems and $150 up to recharge on top of initial price . |
