I agree.

I still want to assume that they probably NOT do this in order to save on building costs. Because if you look at the whole car itself, there isn't another part that is insulated. So I imagine that they probably thought "why purchase insulating foam (or other material) for one stretch of pipe" and just left it at that?

I'd like to do this. My a/c at a level 4 is no cooler than a friend's (old buick) a/c at a level 2.

Well now, those old Buick ACs could be used to freeze a hockey rink. Probably draw off half the power the Yaris engine's capable of producing, too.

I've ony had my Yaris for a couple of weeks now, however it's becoming rapidly evident that Toyota left no stone unturned in its effort to cut cost to a minimum.

I'm not complaining as I wanted an inexpensive, no frills car.

As to why no TSB on this issue.... If they had one, that would be like admitting that there is a problem.

Not sure yet, as I only checked for clearance with the insulation.
I did check my wife's Baja, and the sister-in-laws Aveo today - neither of them has any insulation whatsoever.

I can't see how this mod could possibly hurt anything at all! (other than a few cuts and bruises.)

Are you kidding me? I can't work with gloves. I get cut up if I even look at the underside of a car.

Besides that --- what's a little mod without a little blood?

That is definitely true. Besides, gloves were useless to me when I was smelling some burned arm hair.

If you don't mine, stick a meat thermometer in the air vent and let us know what temp you're getting when driving.

I noticed that mid-morning and after around 17:00 my temps go as low as 37-ish degrees.

If there’s not blood then you didn’t do anything.



I truly don’t think there’s a big issue with the AC as it is stock. I have looked at other cars still sitting on the lot and they use metal lines that are not insolated for part of the run also. I have driven plenty of other cars, SUVs, and trucks but I think the Yaris is as good or better with it’s cooling capabilities. Could the problem start after mods have been done that changes the temp under the hood?

If you have your AC on and you’re not running the fan wide open then why run the compressor and make the motor work harder for no reason?

The cooling was good before, but after doing this mod and driving for about a week, it is a night and day difference.

I’m sure there is a good difference in doing this. I’m just saying that with the car stock it is as good other stock cars that are on the market.
