Enjoy !

 

awesome will do

 

I might do that this weekend! Im also gonna re-insulate the interior too!

 

I'm totally going to try this.

 

Works on every car?

 

I would think so, at least if you have freon cooling with a compressor system.
Just do the refrigerant return line to the compressor, and it ought to get you the same results.

 

Good post. This could possibly increase one's summer gas mileage slightly too. Seeming as how the evaporator would probably stay cooler longer, the compressor would then spend less time cycled on and drawing excess power from the engine and gobbling up fuel. Definitely going to try this myself too.

 

What's up with my post disappearing? Anyway, my old car had foam insulation on the AC lines. After 400,000 miles or so, the insulation was falling apart. I replaced it with pipe insulation from Home Depot. The kind I used is like a foam tube that is split down the length of it. You just slip it on and use a few wire ties to hold it in place.

I might do this to the xD. Not a bad idea!

 

Has anybody seen any issues with this?? As far as I know, it should be OK to do with no long-term damage to any components...

 

Notnthat it matters, but i don't think our compressors kick on and off like old school compressors. These are variable displacement compressors. They stay engaged as long as the AC button is on, but they only use as much energy as is needed, depending on the load on the system.

 

I didn't know that auto a/c technology had come that far. When were the first variable displacement compressors introduced? My 2001 Echo (and every car previous to it) had a solenoid clutch that would engage when you pushed the a/c button or selected one of the defrost hvac modes. The compressor would cycle on and off from a thermal sensor on the evaporator to keep it from icing over. It would also cycle off for over/under pressure in the system and if you went to wot on the accelerator. I was wondering though why I hadn't heard the audible 'click' of the compressor on my xD. I just figured it was because all the parts were still brand new. I swear that I can still feel the compressor 'cycle' when I'm idling in gear on a prolonged downhill grade though.

 

So I looked at the low pressure line on the 1st gen xB and there's only about a foot of metal line before it goes to the hose. It goes back to a metal line below the engine, that'd be a pain to do. I'm going to try the short line and see if anything happens.
