Engine Size: 396
Refrigerant Type: 134a
The equipment is all origional except for the conversion to 134A five years ago. The system was said to be flushed. It cools fine but this year the compressor has picked up a howl. It is not terrible and at some speeds not audible at all. Should I continue to operate the unit?
Might inject 1/2 an ounce of oil in the system and see if the noise calms down. Pressures would be nice as this could indicate more things to look at.
Will do. I'll report back as soon as get time to hook it up. Thanks
Low side is 25
High side is 225
I added 1/2 oz. and nothing changed. Cools great!
Could be on it's last leg. Pressure's seem a little low for that system. If you can I would verify the charge level.
I really have no way to verify how much is in the system. I'd bet it's not sealed very tightly though. It does have a lot of old components remaining that have not been replaced with the conversion. I can't quote the exact charge without looking it up but I do know these old systems are huge.
The car is normally in storage 90% of the time but I like to have things working for the summer months.
Worst case, is it safe to drive if the compressor quits? Might it lock up and throw belts? Thanks.
