system failure
PAG 46
PAG
You will use a PAG 46.
8 oz of PAG 46
day cab 2lbs sleeper no more than 3lbs
new o-rings coated with A/C PAG oil
The PAG oil gets injected through the same schrader valves the refrigerant is charged into and recovered from.
8 oz..PAG 46 or PAG 100 But nothing over 100 it's to thick and don't flow as well.
PAG, the same as any other R134a air conditioning system.
6-ounces of oil and make sure that you prime the compressor as well........ A 1998 Isuzu Trooper with 3.5 engine actually uses 5 oz of pag-46. You can find alot of helpfull information about your vehicle ac system if you go to www.idqusa.com
8 ounces of PAG 46 ...replace the drier/accumulator and orifice tube as well.Flush out the condensor also. You can use PAG 100 (i have pag 100 in one of my 97's and itseems to put out better than the other 97 with pag 46, but we will have to wait and see which last longer) but a service bulletin came out a couple years ago from GM, telling the dealships to go to the pag 46....But, all pag oil is compatible with all pag oil. For example: 4 oz. of pag 50 + 4 oz. of pag 150= 8 oz. of pag 100... DONT USE THE PAG 150...IT IS JUST TOO THICK for this compressor....If you have a hard time getting it all inside the compressor,pour the remaining oil into the hose that goes from the drier to the compressor.(suction side...where you add 2-12 oz cans of 134a) Then turn it by hand about 12 revolutions.... And dont forget to evac the air from the system. A/C systems cost toooo much to cut corners trying to save 10 bucks.
