If your air conditioner needs repairs, it makes sense to switch to the newly required environmentally safe refrigerant
Performing the Retrofit: Before any work is initialed the system has to be checked for leaks. This is done first before any seals are broken. Checking for leaks first will evaluate the condition of the existing system before any repairs are made. It is best to use a halogen type leak detector. These testers are typically rated to detect leaks as small as 0.1 pounds per year. Ask your air conditioner shop to use halogen type leak detector rather than electronic dye which is not as accurate for detecting leaks. Once the system is tested for leaks note if any repairs are to be made. Our vehicle had a leaky suction line running from the evaporator to the compressor. A new #10 refrigerant hose was made up and will be installed with the new compressor.
NOTE: When installing the new compressor you must drain out the oil and add ester oil and install (for retrofit only).
Drain the oil from the new compressor into a measuring cup. Then replace the same amount with ester oil and install the new compressor drive belt.
