Also know that this vehicle is really a Ford Ranger, and made in USA. Some of the Rangers had factory AC, some had dealer-installed, parts were not necessarily the same.

Re: Toyota Sienna rear air weak

That's a good idea for him to check.

Also worth checking is to remove the rear case and make sure that the rear evaporator fins are clear and not all clogged up.

Re: PAG-oiled components in former mineral oil systems. Corrosion Issues?

15 years ago I bought a rebuilt compressor that came filled with PAG oil (I tested it). My '88 Mazda truck is R-12. I drained the oil from the compressor, added 6 oz. R-12-type mineral oil, rotated the compressor about 15 times by hand, drained that out. Then I repeated that. Then I added the correc...

Re: Thanks for the add and RV2 questions

The poor fan performance can be several things. Obviously check the ground at the fan motor & the overall health of the motor itself. Power connections from the switch to the motor, resistor etc. Check the air door operation, box seals etc. Also make sure that the exterior/fins of the evaporato...

Re: refrigerant and oil questions

My comments below in Capitals. I need to disconnect a couple refrigerant lines in order to replace my heater core on a 2008 Nissan Frontier. I'll have a shop recover the refrigerant, but plan to recharge myself. I have a few questions... 1. I assume the recovery process removes some oil - do the rec...

Side can tap

bohica - I've thought about getting/using a side can tap, I have separate top tap units for R-12 and for R134a. Exactly why do you like that type better? thanks.

Re: 1991 Mercedes R12 Troubleshooting

There is UV dye compatible with R-12, have some in my 1988 Mazda truck (still R-12). But one needs the correct injector for this if there's still R-12 in the system, so my mechanic did this for me. If all the refrigerant is out, then UV dye can be simply be added, then the system evacuated and new R...

Re: Adding oil after full system replacement

Basically just one line and the two stubs going through the firewall to evap core need flushed. I just ordered a flush gun so I'm gonna do it myself now. George Costanza - good, flush those two lines then. Is there a risk with starting out with 9 oz in the comp? Yes, do not engage the compressor wi...
