Grand Prix 2000 A/C Condenser

[andreval]

I have to replace my A/C condenser. Will I need new O-Rings or Gaskets?
Is there a special procedure to replace the Condenser ?
Thanks Andy

The lines at the condenser use o-rings. This is not a fun job and a real PITA. You plan on doing the work DIY instead of having a shop do it? In order to remove the condenser you'll have to remove the radiator, dog bone engine mounts, cooling fans and everything else in the way.

Also, unless all of the R134a has leaked out you'll need to evacuate any of the remaining R134a out of the system. After the condenser is replaced and everything is back together before adding back the R134a you should run a vacuum check to insure there are no leaks and remove any possible moisture from the system.

Plus be sure to add approximately 1 ounce of PAG oil directly into the condenser input line before installing it and the refrigerant lines.

You will need to pull a vacuum on the system down to 29" of mercury. This will boil off any moisture that may be in the ac system. This needs to be done in order to stop the moisture from freeing up the system.

Also doesnt moisture mixed with r134a create acid and corrode away your AC system from the inside out? Thats what I heard

i agree with comments but if u no the parts are bad & want to save $$ install them then take it to shop 4 the recharge.im assuming system is empty

If thats the case Tim then it will need a flush and possible parts replaced. One good way to tell is remove the orifice and inspect the screen. That is the reason why there is a receiver-dryer or in our case accumulator. It contains desiccant to absorb moisture. On any major A/C repairs the accumulator should be replaced as well along with the orifice.

Duh! Must have had a brain fart there for a second. HA HA Heating and AC was the last class I took for my degree, did pretty good in it too. Funny how fast one forgets things....
