Dryer installed backwards

Cletis too on Wed August 29, 2007 1:30 AM User is offline

Year: 56
Make: Chevy
Model: 3100
Engine Size: 350
Refrigerant Type: R-134
Ambient Temp: 94
Pressure Low: 7
Pressure High: 230

Being a newbie, I didn't know there was a specific in and out port for my dryer. So, as Murphy predicted, I put it in wrong. It charged and was blowing cold, around 40 degrees, but after a test drive it started blowing warm air. I put the gauges back on and was showing a vacuum on the low side. I called the Hotrod Air tech who correctly diagnosed the backward dryer.

I turned it around and recharged it to the pressures listed above. Now it only cools to about 60 at idle and about 70 when reved. The Hotrod air tech says I probably ruined the dryer and a new one will fix it.

What do you guys think?

Ehis post answered by Iceman in another thread shows the insides of accumulators and dryers. You can change it, but keep in mind, if it went into a vacuum, the disicant may have broken and you may have it thru the lines. Check very carefully for that. If it did break, you are going to need to flush the system or it will keep clogging the expansion valve..I would check the expansion valve for signs of disicant in the inlet screen...Hope this helps.

What kind of system is this? Stock, with original A5 and hot gas bypass valve? Aftermarket, with who knows what?
