Re: Help needed. A/C blowing hot air

This car has a Delphi CVC compressor and a TXV. A particularly low refrigerant charge might still show seemingly ok static pressures, enough to allow compressor clutch engagement, but it will seriously hamper correct compressor displacement regulation by starving the evaporator, and this means warm ...

Re: 1996 Jeep Cherokee A/C trouble

Recovery, leak test and proper recharge by weight into vacuum procedure + new receiver dryer + new TXV (and any o-ring that got disturbed) is the way i'd go here IMHO. TXVs are precision metering devices that suffer wear and tear, and their design often gets improved overtime.

Re: 2004 honda Accord low/high sides same preasure

Ice32, among other claims, seems to improve oil return, i.e. more oil will be in the compressor rather than elsewhere across the system, according to what the product claims. Definitely won't cause sealer like issues.

Re: Options to fix this compressor, 2001 Honda Insight?

I'd say new aftermarket comp. Flush, new double end capped PAG 46 oil, new condenser, new TXV, new o-rings, new valve cores, new caps. Everything has a beginning and an end. Do it once, do it right. Remember that's a 20 year old car.

Re: 2014 Silverado 1500 AC Trouble

Some TXV designs are inherently noisier than others (i'm quite sure the OEM mfg for my car's TXV, TGK, updated the design sometime around 2003 in order to fix a noise issue caused by a too thin operating shaft that vibrated too much under high HPs IIRC; they changed it to a thicker shaft, encased th...

Re: Murray AC Compressor Questions

Looks like a single sided swashplate variable displacement compressor. With these ones, usually ( some Denso 5SE units are an exception apparently ) the compressor housing features a drain hole that allows the entire crankcase to be both drained and refilled with oil. The one on my car has one point...

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

See? Vent temp climbed down as heat load (humidity is also additional heat load) increased. I'd have turned AC on for a few mins during any warm spell. Rather than adding one ounce or so, i'd recommend you visit an RRR equipped pro and have everything recovered, weighed and restored to proper spec. ...

Re: 2007 impala ac issues

With the refill i was going to have a full evacuation, vacuum test, reoil and refill. As JohnHere said, ensuring the proper amount of oil is in the system is a way more time consuming process than just hooking a machine to the system. The "reoil" the RRR stations usually do is actually in...

Re: 2007 impala ac issues

A combo of a dirty condenser and a worn/malfunctioning condenser fan drive system can do that. Perhaps the weather warmed up after the first week. By the way that's a CVC compressor and the one on my Euro car has an overpressure valve (a little nut looking thing; that colored dot thing held in place...

Re: 2002 Civic Si – Evaporator temperature sensor

Your 2002 Civic should have the block type expansion valve. In that case, there's no equalizer line, yet the valve is still, technically speaking, externally equalized, since the refrigerant is directly able to exert force upon the diaphragm as it leaves the evaporator. Depending upon the valve's de...
