Holden Torana 1978 Problems

WE PUT your question to Mark Lynch of Carcool Airconditioning and his response was that it probably wasn't worth fixing the aircon. He says any repair becomes a restoration with a system fitted to a car nearly 30 years old. If the compressor is black, it is an original Delco and would need major work to be suitable for new ozone-friendly gases. Run the car on petrol occasionally, otherwise seals and other bits in the fuel system dry out and harden, which can lead to other problems.
