AC Line

[crimsondragon]

What is that steel tube that runs along the firewall for? There's a twist cap on it that has the letter H on it. I need to know if this line gets hot or anything like that. If it does I'll need to relocate my pressure sensor.

Thats the High side of the A/C lines. And yea, its gets warm... I wouldn't say hot.

Not hot enough to burn right? Does it heat up when the AC is on or when the car is on?

It's the output line of the compressor. It's how air conditioning works: the compressor crushes the refrigerant down to a hot gas, it's run through the condenser to cool and liquefy it, and it's allowed to expand and suck up heat in the evaporator, then back to the compressor. The high pressure side should be just about hot enough to burn you. If not, you may be low on refrigerant.

? so if i removed my ac condensor and i wanted to remove all the lines, i didnt take out my AC compressor yet, i could take out the output line with no effect.
thanks,

Yes, if you're taking out your compressor and condenser, you can remove the hard lines as well (as they obviously won't be used since you have no A/C system).

i didnt remove my compressor yet

You can still remove the lines.

It's against Federal law to open the 134A to the atmosphere, but I've yet to see a freon cop on the street. As far as the car goes, it won't care.
