Absolutely !!! And likely the new R4 compressor would last a ton longer. It's lower lifetime in dual-AC vehicles has been documented due to liquid refrigerant from the rear getting back into the compressor.Wyattgc wrote:Would I need less r12 if I did seal off the rear ac?

Re: 1990 suburban r12 to r134.
Someone here will know if this vehicle is able to be converted successfully to R134a. Original R4 compressors worked OK, had marginal lifetimes when used with rear evaporator, so blocking off the rear should help. There are conversions to use more-modern compressors in this however. My guess biggest...

Re: 2002 Suburban Correct Compressor
2.5 years ago when I needed to replace the compressor in our 2005 GMC Yukon Denali I installed a brand new Denso one, OEM supplier, was bout $200. Not worth saving $20 to install a rebuilt. Make sure to get one set up for dual or front-only air, they typically are different. I installed a Four Seaso...

Re: Can someone check my cooling stats please?
Vent temperatures get lower when driven. Try it out on the road on a hot day.BOON250 wrote:If I rev to about 2500 the high side goes to 200 and the low side stays at 19-20 . Never moves. Vent temps stay the same.
Your 2500 rpm pressures seem a little on the low side.

Re: ac problems
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.srkreutemazda wrote:2000 Mazda b2500 with 2.5L engine. I'm in Fl.

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...
