AC outlet temp

My 4 cyl, 03 Camry's A/C does not seem very cold.

Outlet temp while driving 55 mph (control set all the way cold, recirc on, fan 3) is 41 degrees, and only stays at that temp very shortly (a few seconds). Most times the temp is around 45.

By comparison, my gen 3, 4 cyl Camry w/134a has outlet temps of 37.5, and does not cycle off as fast.

Ambient temps were 88 with the humidity around 65%

Do these numbers for an 03 Camry sound correct? Subjectively, I can tell you the old Camry feels like it will freeze you out, while the new one feels very "luke-cold", and in-effective.

Thanks

Datsun 810 Typical vent temperatures are 38-40F at ambient temp of mid 70s F. The evap runs at 5-7 degrees lower.

Finding what temp your car should run at will be a function of many variables, so a comparison with a similar car will be needed.

I agree 200%. My 92 was so much colder than my '03. And the vents were in much more convenient places. Could direct it just where needed it most.

Your new Canry's temps match what I get under similar conditions in my '03 Corolla.

my 97 4 cyl air I have to keep turned down more towards low end of the cold temp part of the dial. Even with temps in the 90's and high humidity. Turning it all the way up is very cold!

I am willing to bet the current generation 4 cyl Camry's poor A/C performance is EPA related, especially now that the car is ULEV rated. The Compressor runs less than the previous generation, or perhaps the compressor has less drag on the engine. Less idle up/drag on the engine makes for less total/cleaner emissions

Other than a mechanical defect (defect in the electronic temp control dial, etc) or low refrigerant, I can't see any other way for the poor A/C performance.

A 5 degree difference may not sound like much. But the short duration of luke-cold 41 degree air, coupled with a long duration of rather warm (by car A/C standards) 45 degree air, makes for poor performance.

I have an 2001 solara with a v6 and the ac will freeze you once it has about 10 minutes to get rid of the initial heat. I have felt colder ac, but this one is a little better than average.

I have tinted my windows too. The tint is legal (35%), and that helped.

The V6 (1MZ-FE) seems to be the key. Many folks here mention cold A/C with the 6, but the new 4 (2AZ-FE) seems/is lacking for what ever reason when compared to the previous generation.

Actually the refrigerant is the same as my 94... R134a. The compressor does not cycle on as long, and would seem the result to lower emissions/higher MPG.

Now with the ULEV rating on the Camry, despite a much more powerful 4-cyl engine, A/C performance suffers. IMO, worse performing A/C from the previous generation is B.S., regardless of the cause

About the only parallel I can think of is with Honda. Back in the mid 90's Honda was shooting for a LEV/ULEV rating, and A/C performance in my estimation went waaaay down hill. My mom's ULEV Civic has A/C performance that is absolutely pathetic. I was reading about a new Honda ZLEV engine that at times has negative emissions... ambient air is dirtier than what is emitted. Guess that A/C will be known as a heater.

the best thing to do initially is to drive with recirc off, AC on full, and windows opened for a couple of minutes. Then close windows and turn on recirc. Some people think that recirc will cool faster. It does not initally. Your ac system can only drop the temp so far per pass. It is easier to cool 90 degree out side air than it is to cool 140 degree inside air.

The manual even states this.

Is it known for certain that the A/C is required to be running during the emissions certification cycle? If so, then for consistant test results, the A/C compressor would have to be cycling consistantly or the compressor engaged all the time ... wouldn't you think? Or ... the A/C is left OFF for certification. I would not blame the LEV/ULEV/SULEV/ZLEV... blah blah blah ... just yet. There may be other reasons, i.e. the recirc loop within the condensor or "smart" electronics governing A/C operation.

My 03 Camry's AC works great. I live in California where it gets in the

100's. Even at these high temps the AC works just like all my other Camry's (Gen2 - Gen5) that is to say it will freeze you out.
