‘93 Ford
Taurus, AC Hose Question
Q: I just had a rebuilt engine put in my ‘93 Taurus and the mechanic
left the A/C hose unhooked from the compressor because he said my car
was empty of freon. I did not have a problem with my A/C before. He said
it would burn out the compressor if it was left hooked up without any
freon. I think it should have stayed hooked up so trash and etc. stay
out of it. Who's right?
A: You
are right, he’s wrong! Get that A/C hose hooked back up ASAP! The refrigerant
in today’s vehicle’s not only removes heat from the passenger compartment.
It also carries the lubricant that is critical to the A/C compressor.
There is a low pressure switch that automatically shuts down the A/C system
if there is not enough refrigerant in the system preventing major damage.
Keeping an A/C system closed up also prevents dirt and moisture from entering
the A/C system. Moisture causes damaging acids to form inside the A/C
system.
