Re: Need help recharging the AC on a 97 Jeep Cherokee Sport
when I needed to redo the ac on my 90 xj, I just had the system vacuumed out
and made sure it stayed on vacuum. then I picked up one of those conversion
kits at AutoZone and put the connectors on. they only go on one way. after
that was done, I connected up the can of 134a and started the engine with
the ac on and started to fill it. I kept an eye on the pressure (gage also
available at AutoZone). Pretty soon I had 45 degrees at the vents in the
dash and was good to go. Once a year I had to give it another can. Other
than that it was working just fine.

Re: Need help recharging the AC on a 97 Jeep Cherokee Sport
Not a good method to use! Each manufacturer has a specific amount of
refrigerant they require to be installed by weight. You do this with the
system off and measure by the total refrigerant installed. Once you have
the correct amount installed you need to check the super heat combined with
discharge air temp, ambient air temp and the high and low side based on the
temperature chart anything else is just a SWAG and not contusive to a good
installation. Also in a new or rebuilt system you need to draw a 500 micron
vacuum to get all the bad stuff out and re introduce the correct amount of
compressor oil.
