aftermarket A/C
Hi ,
my 75 911 didn`t have the knee pads when I bought it and had installed an aftermarket A/C which was removed. I bought for nearly nothing a complete aftermarket A/C including the dash and underdash elements so I can make my interior descent again. The question is what īd I do with the other components? There`s a Sanden 505 compressor-how do I know or control in what kind of state heīs in? Thereīs a condensor for the motorcompartement Thereīs a frontblower make cccoool seems to be from the volkswagen group. ok ,the tubes and drier I will replace. The parts look pretty good but is it worth using them? Id like to keep the blower at least while he fits the underdash elements... I`m also told that with the new refrerants they are compatible with the old R12,so thatīs a plus. thanx in advance |

I think if any of your old components used R12, you will have to replace all the fittings on them because R-134 requires different fittings to handle the pressure differences.
The old lines are useless, they're actually perforated and can't handle R-134. You need 'barrier' lines. |

yes, off course thank you.
But what I`m interested in if anybody has some information,such as electrical schema,installation guide,etc...anything. I think this system is from the seventies and perhaps Coolair ?? I can`t find much info on the net about it. I`ve seen comments passing by that it is useless, still Iīd like to use it because it looks simple and I`m not living in a very hot climate.... |

The only place that gets changed to new ports is at the compressor where the gauges are connected. The old hoses are just non barrier hoses, used in a era when R-12 was 30 cents a pound. That is why you need the new barrier hoses, so you don't have to charge the system every year or even more often. Once you have the brackets and blower motor enclosures gathered up, then you will need a lot of new parts. Unless the old condensers you buy have been capped and sealed (unlikely) they are not really worth trying to use. Same for the evaporator. The Receiver-dryer HAS TO BE replaced.

See? There you go. New lines, new fittings on the compressor, and old parts not worth re-using.

ok, at least I can keep the compressor...
but still this one for sale at ebay has the same A/C as I have,does that mean that all the cars that have it can`t use it? |
