DIY: A/C Insulation - Page 8 - Toyota Yaris Forums

Lafiro · 07-09-2009, 01:03 AM

Now im trying to figure out if the cold line we are feeling on the top of the exhaust/left of the motor is actually going into the cabin, or coming out?

The pictures above show it coming out, meaning what is the point to keep something cool thats not going to the cabin to make us cool!?

Someone has to explain this better, or maybe there is another place to insulate this?

Also has anyone looked under the steering wheel, right side of the floor, and also seen how close the two pipes come to each other? Seems like that needs insulation as well!

Yes, that explination worked out great. Thanks.

I will try doing this tomorrow, couldn't today because I was in the process of installing fog lights.

What does the dryer do?

The dryer removes moisture that may have entered the system to protect the compressor.

So....I would assume that the dryer has some type of rating on it, meaning the amount of moisture it can remove out of the air in a given amount of time. With this new mod, more moisture will be present in the line. How do we know that the dryer will do it's job with the extra moisture. It might work for now, but a year from now, or 2, or 3, will it still be able to work correctly or will it break prematurely due to having to work harder?? Anyone have any longterm data?

The drier will trap moisture and debris that entered the system when it was assembled and charged. As the a/c system is a sealed system you will not be getting any new moisture in the lines until a leak develops and then you have a whole new problem... no cooling. If you replace a compressor you change the drier too.

So whats the point of a dryer?? The way you describe it is that once it dries the initial moisture in the air when the AC is used for the very first time, then dryer is useless?

When you charge an AC system, you first draw a vacuum on it to pull out as much moisture and particulate as possible. It's impossible to get every bit, so that's where the dryer comes into play.

Thats why they need to have a removable dryer. Has a shut off valve before and after the dryer. After the dryer has done it's job, shut the valves off and remove the dryer. Clean the dryer out and reuse it on the next car coming down the belt.

So I took a digital thermometer and at a standstill in the shade the temperature goes to around 42f. And when I drive it goes to a low and steady 35f. The temperature outside was 78f. This was done with the fan on 2.

I will be wrapping the pipe today hopefully and will let everyone know what happens.

I am not sure if the mod will benefit you. If you're already getting 35-degrees then thats not too bad. Of course, NYC is around 78-degrees whereas Houston is running around high 90's. That can make a difference between A/C.

Who knows, maybe the mod will drop yours down to 33-degrees!

I got some large size heater core tubing (that rubber stuff that connects your radiator to your motor. Going to wrap the AC pipe with foam, then cover the foam with this rubber tubing. Its oil/fluid resistant, and also hi-temp. Should work well, and the dull black color should make it look fairly stock/stealth.

will do... might not be till next week... I got soccer tonight so I probably wont pick up the foam until tomorrow... and then to make sure it looks nice I want to take my time... so my work will most likely be slow.

I'll be cutting a slit down the tube (think split loom) and then either zip tie it closed... or better yet... maybe silicone sealant.

ok... started working on this... The rubber heater core tube fits perfectly over the pipe.... except when the pipe bends. Going to stop by home depot or lowes on the way back to see if I can find a thin type of foam to cover the pipe. There are a few corners which which are too tight for me to get the hose to bend around, so I'll have to cut weird wedges to cover the corners. Then i'll just have to wrap black electric tape neatly around that to make it stay in place well. Even if I don't find anyfoam... I'm sure the rubber heater core tubing will insulate it fairly well. Will post pics when i'm done.

Ill be honest, I wrapped mine up in fiberlass(dads idea), and then aluminum tape, and it did pretty much Nothing to lower the temps.

Im about to remove it cause its a messy look. I will go the foam route though soon.

And like I said, it only drops to that temp at the lowest. Usually when the car is moving, and the compressor is active, it will drop to the upper 30's. And as soon as the compressor stops, it can go as high as 47degrees. If the car is sitting doing nothing, it will go between 40 and 47degress. This is all in farenheit.

Hmmm...I guess do try the foam approach. But even hi-30's with no insulation seems about fair. You tell me, what's considered hot weather in NYC? Do you do a lot of stop-and-go traffic or are you actually able to cruise a longer periods? Because if mid-80's is about average and since the our A/C systems vary according the the weather and driving conditions, you might be able to get that sucker down to 35-ish?

Heck, anyone from Arizona or New Mexico try this mod and still get colder air?

Lafiro · 07-23-2009, 04:08 PM

It ranges, the past couple of days have been 78-84degrees. And the temperature remains around the same levels.

Now thats a silly question about cruising, or stop and go. Where do I live? lol Its all stop and go, even the highways 80% of the time.
