Engine Size: 3.8
Refrigerant Type: r134a
Hi.Great site.I purchased this 98 lesabre in september 2010 with a/c inop..The previous owner said he had it charged in Aug. of 2010(i have the receipt of the charge) and it leaked out.The only visual leak I can see(oil residue) is one of the fitting that connects to the condenser.What do you think I should do?Check the pressures with a guage set?Replace the seal at that fitting?I like to see if the compressors good before i really do too much to it.Also,does that fitting use the washer type seal or an o-ring?Thanks for the info!
Almost guaranteed to be leaking at compressor shaft seal and compressor belly-- seen hundreds of them in your vintage- the V-5's used single lip seal shaft seals up until sep 2002, so yours is a dead ringer for a compressor reseal....or you can buy a new one....
Some dye and a good old-fshioned leak detector would be great at this point.
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......
Well I put a charge on my buick.It got a tad cool.Shut it off and heard a hissing.Found that my condenser is leaking at the bottom(seen some green dye)anyway.......Im going to replace the condenser and was wondering what other parts I should get replace also?Thanks
