Okay wow a big can of worms were certainly opened on this job. This is a cautionary tale. Brought my truck in for service and of course fixing my AC. Turns out the fan clutch was bad which meant not enough airflow going through the condenser which apparently had the compressor compensate by increasing the pressure which caused 4 leaks in the condenser. I could not remember last time I changed the coolant but my thermostat was sticking which was causing minor overheating. I never knew the " mechanical " fans had a clutch in them.
I bought my truck with 14kms on the odometer now I am at 122,231kms. How often does the fan clutches need replacing?
