All vehicles manufactured from 1 January 2017 will operate using an A/C system filled with the new R1234yf refrigerant.
This means vehicles built before January 2017 designed to use R134a refrigerant systems will need a manufacturing upgrade of the vehicle A/C system for the R1234yf refrigerants to comply with new EU regulations.
The update also brings with it a new type of compressor refrigerant oil for workshops and suppliers to be aware of.
In with the new
Shrader cooperative brand uses ND-oil 8 for its R134a type refrigerant compressors, a PAG 46 oil. The new refrigerant type uses ND-oil 12, also a PAG 46 oil but with additives specifically for the R1234yf type refrigerant.
However, this doesn`t mean the two oils are interchangeable; while ND-oil 12 can be used for both R134a and R1234yf, it doesn`t work the other way around and ND-oil 8 cannot be used for R1234yf type refrigerant.
