Re: Trouble in paradise. Thanks in advance!

Scott, A few questions. What make and model of vehicle are you working on, and does it have factory A/C? You said that as you began charging it (through the low side), the low pressure shot up to 115, but the can wasn't emptying. Since you then immediately shut everything down, how do you know the c...

Sorry...accidentally hit submit before cleaning up my previous post. Buttons on my phone are just too small.

Re: Toyota pickup AC questions

[ Rented the equipment and checked pressures. It was low on refrigerant as expected, but not low enough to not kick on the compressor. Do you know for sure that it was low on refrigerant? I ask because it's not possible to tell how much is in it by pressures alone. Recovering the charge and weighing...

Re: Peanut not sitting flush

If it sits flush when fitting it by hand but not when you tighten the nut, it seems to me that the threaded stud isn't perpendicular to the matting surface, as Mr Bill suggested. Try tightening two nuts (jam nuts) against each other on the stud, then turn it 180 degrees. Now, remove the jam nuts, re...

Re: A/C Compressor Issues

The specs that I have for 2003-2006 Tahoe, all engines, are as follows: Config. 1: Without rear A/C, 25.5 ounces R-134a, 8.0 ounces PAG-46. Config. 2: With rear A/C, 43.0 ounces R-134a, 11.0 ounces PAG-46. A little guesswork comes into play here. But if you have Config. 1, you probably already have ...

Re: Toyota Sequoia poor AC performance

I don't think it's the compressor, which seems to be putting out sufficient pressure. In fact, both high-side and low-side pressures are elevated. The pressure on the low side, 55 PSI, corresponds to evaporator temps in the high 50's. So I can see why you aren't getting enough cooling. In addition t...

Try this site's sponsor for an R-134a compatible receiver/dryer. Tim at ackits.com might have just what you need.

Re: Toyota pickup AC questions

Thanks John. I texted my neighbor this morning and she said the AC still in fact is working, although still not as cold as it should be. I want to assume the system is now reliable (even if I’m a hair low on oil... ) Good news that the system is still working, although not as cool as she would like...

Re: 2008 Honda Pilot A/C problem Help PLEASE!

Larry, my references say that the capacities for your vehicle are 24.7 to 26.5 ounces of R-134a and 9 ounces of PAG-46. How much oil did you put in it and where? Did you distribute it among the new components or put it all in the compressor? Did you use a manifold gauge set and refrigerant scale to ...

Re: 2008 Toyota Yaris 1.3vvti fitted with Denso 5SER09C compressor!!!!

I can't find any specs for that compressor, either. But as for the air gap, .020" is the standard that I see most mobile A/C techs going by and is the one I use. Any wider than that and the clutch might not engage, especially an older unit having a somewhat weakened coil. You can go tighter as ...
