Here's why:
* Regulations are strict: Refrigerant types are highly regulated due to environmental concerns. What was used in the past may be illegal or harmful to use now.
* Model variations: The refrigerant used can vary even within the same model year depending on the specific engine and climate control system.
To find the correct refrigerant, here's what you should do:
1. Check your owner's manual: The manual should specify the proper refrigerant for your vehicle.
2. Consult a qualified technician: An automotive technician can identify the correct refrigerant using a refrigerant identifier tool or by looking up the vehicle's specifications.
3. Don't guess: Using the wrong refrigerant can damage your AC system and is harmful to the environment.
Remember, working with refrigerants requires specialized training and equipment. It's always best to leave it to a professional!
