Air Conditioning on Turbo's

[MichaelDay]

I have not been thrilled with the temperature of the air coming out of the AC on my 03 Turbo. The dealer checked it and said it is "in spec". I checked the Service Manual and found the following:

A/C PERFORMANCE TEMPERATURES- (NON-TURBO ENGINES ONLY)
Ambient Temperature 21°C (70°F)
Air Temperature at Center Panel Outlet -2 - 6°C (29-42°F)
Compressor Discharge Pressure 999-1206 kPa (145-175 PSI)
Accumulator Out Pressure at Service Port 122-221 kPa (18-32 PSI)
Ambient Temperature 38°C (100°F)
Air Temperature at Center Panel Outlet 11-19°C (52-65°F)
Compressor Discharge Pressure 1584-2136 kPa (230-310 PSI)
Accumulator Out Pressure at Service Port 220-324 kpa (32-47 PSI)

A/C PERFORMANCE TEMPERATURES- (2.4L TURBO ENGINE ONLY)
Ambient Temperature 21°C (70°F)
Air Temperature at Center Panel Outlet 6 - 16°C (43-60°F)
Compressor Discharge Pressure 1139-1795 kPa (165-260 PSI)
Accumulator Out Pressure at Service 195-319 kPa (28-46 PSI)
Ambient Temperature 38°C (100°F)
Air Temperature at Center Panel Outlet 17-28°C (63-83°F)
Compressor Discharge Pressure 1932-2484 kPa (280-360 PSI)
Accumulator Out Pressure at Service 332-512 kpa (48-74 PSI)

So at 100 degrees, the air coming out of the non-turbo AC vent is 11-18 degrees cooler than out of the turbo AC vent. That would result in reduced AC cooling. The AC compresssor and accumulator pressures are also significantly higher on the turbo model than the non-turbo.

I haven't noticed any difference in the air conditioning temp from my GT and my wife's '01. I have to turn the air cond down in my GT as it gets too cold. I think your dealer is giving you the run around. Have it checked by another dealer.

I have found our A/C to be fairly in-efficient. Luckily I live in Oregon and A/C is only needed about 1 month out of the year (90 degrees or above). My 1989 Ford P.U. will out cool my 03 GT twice as fast and a number of degrees cooler, in-fact if I have my A/C on high (in the GT) and am sitting in the sun...it's still uncomfortably warm.

I agree...my AC isn't all that...I was gonna have it checked today when I go get my oil changed....

Our AC in Texas blows snow flakes out if put on full cold. GT, 5 Speed, no problems here.

my first gt ( electric blue) ac was ok nothing great ,havn't had to use the new gt ac yet in the ( inferno red) yet been very nice and cool here for about 2 weeks

I have had no problems with my AC. In my old 2001 PT the AC would take a while to get cold, or hot. I have noticed with the GT it works MUCH faster.

[Sturdevant]

2003 GT 5 speed. At an outside temp of 81 F, the AC on full, during cruising it gets down to 55 F, at idle it warms up to 60 F.
(Just measured)
This does not seem as good as some others I've been in but apparently within spec.

AC seems to work good for me, I've had to turn it down at times. Black car, black leather interior it gets real hot in the summer but the AC cools it off.

[dreamcruiserguy]

Yes, my family and I own lots of cars and the air in the GT PT is not the best at all. I also think the air adjustment in the vents is not that good .[8)]
