Insulating Airconditioning Lines

[JimX]

I was thinking, would it be worth the effort of insulating the air conditioning lines, especially the ones that go along near the exhaust area? The main reason I'm thinking about it is I have a whole lot of thermal wrap which I pulled off my rusting dump pipe recently, and it's kind of in bits and pieces and not really useable for much else. I was thinking I might salvage what I can and try wrapping it around some of the aircon lines. Anywhere else I should try wrapping it?

My brothers R31 has silver, alfoil type sleeve over the lines that run up past the exhaust manifold.

Don't think it would be standard factory fitment, but it may have been, anyone clarify?

Protecting them from the radiant heat from the exhaust manifold is a worthwhile proposition.

Its not going to effect ac performance a great deal, but it will extend the physical life of the rubber hoses.

I've got that foil stuff in that area too, but I think there are lines which run past there forwards. There's probably not a whole lot of difference insulation can make while the car is moving, but it might make the air a little cooler when idling in summer traffic. I guess I'll just try it and see, I think the only other use for this stuffed heatwrap is to throw it out.

I did it on my last car (Berlina V8). I didn't notice any difference in the A/C efficiency, but I don't see why it can't help? My lines were thin metal pipes that went from the gas cylinder to the A/C compressor and condenser.

Heck... why not!? =-]
