I have a 94 Chevy 1/2 ton 4.3 V-6 engine. It needs the air conditioning
system to be charged. It takes the new type of fluid I think its the 134
type. Any way with the ease of the kits on how the hose attaches to the can
I thought I could do it. The Chilton book doesn't say anything about
charging the system.
Once I have the can and hose attached where do I attach the other end to the
car to start charging. Is there a picture somewhere so I would know exactly
where it is?
Thank you Ryan
Without the proper equipment (vacuum pump, high+low side gauges, etc.)
you'll severely damage the system. It needs a charge because it has a leak.
Take it to an A/C shop and have them find the leak, fix the leak and charge
the system. It'll cost you more to replace A/C parts after you under or
overcharge it than it will to have it properly serviced. A/C is NOT for the
inexperienced. When you start calling R-134a refrigerant "fluid," it's an
indication you need to have someone do it for you. I'm not trying to flame,
just trying to save you some $$$ in the long run.
I agree with Doc. The R134 is not as forgiving as the r12. If the system
calls for needing 4 oz., then you need to add EXACTLY 4 oz. Too much and
it's warm, too little and it's warm.
some say the 134 isn't as cold as the r12, but I disagree. Most of the
time, it's because they tried to charge the system themselves and got too
much or too little. I just had mine charged at a local shop and it's right
on the money. It will freeze you out! The majority of the time, I have the
heater/cooler knob at about half way to be comfortable (my wife still wears
You call an AC shop, Make an appointment.
Let them diagnosis your problem.

that is what needs done.
