Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

Stuff can still lodge inside the fins and block airflow even though they appear clean. You want to see light shining through them.

Re: 1979 F150 will not cool below 60F register temps/evap partially warm

So you basically had a nearly jammed closed TXV that starved your evap big time (hence only 10% of the evap cold).

That's why i'd use either Denso or second hand TXVs only, if OEM ones weren't available/were made of diamond.

Re: 93 Toyota Pickup recharge challenges

What i really wanted to stress here is that if everything one has at disposal is refrigerant cans and newbie-level experience (uncomfortable with gauges and what not), then he's/she's supposed to stop and take the car to an experienced and suitably equipped professional who will charge the system th...

You're welcome MMCG7, and i appreciate the fact that you got my nick right. I told you that only because i don't want you losing time and money needlessly over something that sometimes is just best left to a professional.

Re: 93 Toyota Pickup recharge challenges

I'm afraid MVAC isn't newbie-friendly stuff. I'd recommend you hand this over to a pro.

Vacuum is only one part of the leak test. The other is, you guess it, check how well it holds pressure. Again, this is pro stuff.

Re: 93 Toyota Pickup recharge challenges

Yes, do a deep vacuum (after making sure the system is leak free) and then charge by weight into that deep vacuum. Anything else than that, you're causing serious compressor wear. Professionals regularly carry the entire process without turning the AC compressor on, it's the only way to make all the...

Re: Ford Focus MK2 break 2006 AC issues

"Most vehicles should turn on the radiator electric fan immediately with the A/C turned on" BINGO Well, mine turns on only once the liquid line pressure gets high enough. Engine control units are often programmed so that the AC clutch gets disengaged below a certain rpm value to prevent t...

Re: 93 Toyota Pickup recharge challenges

Is the TXV's sensing bulb firmly attached to the evaporator's outlet? And properly insulated so that it's only sensing the evaporator's outlet temperature, too? Ester oil is a great solvent so the dark oil you're referring to might well be Ester. Little oil found inside the compressor is normal occu...

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

PAG Blue or PAG 125 are the commercial denominations of possible equivalents to the oil originally featured in these compressors, a slightly thinner PAG 125 oil. But PAG 150 is basically the same thing.

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

Yes, some oil always comes out with the recovered refrigerant, but the recovery machine has an oil separator and a measuring scale/bottle. If the technician isn't a complete idiot, the same amount recovered will be injected back into the system right after the vacuum is done as fresh oil. By the way...
