grand prix condenser

Year: 1999
Make: pontiac
Model: grand prix

how similar is a radiator/condenser setup on a 99 grand prix compared to a 96 seville? i replaced the caddy radiator 2 weeks ago and it was easy. they both come out together and its not hard. my grand prix has a leak in the condenser and i am wondering if the replace procedure is similar? a shop that found the leak today wanted 900 to do the condenser. they quoted 274 for the condenser and 75 for the receiver. thats a lot for labor to R&R and evac/charge. i can get a new condenser for 90 at the local boneyard. they sell lots of new/used parts. i have a vacuum pump and gauges so i figure, give it a shot.

You can do it... not too bad at all- should slip out from behind radiator- pull cooling fans out- slip radiator back- then slip out condenser- no need to disconnect radiator tranyy lines or coolant hoses- as I remember

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

i'm not that talented. i decided to pull the radiator so i could flush it out. there was a nice big green stained area on the bottom of the condenser from the shop checking it yesterday. the lower 4" of the condenser is really beat up. must be all that road debris. i checked over the radiator for any obvious signs of corrosion and it looks good. i put in 1.5lbs of 134a. the tag says to use 1.88 but i only had 2 small 12oz cans. i got 35-39deg at the center vents. the high side pressure is staying at about 160psi. i think i need to put in a little more 134a.
