Trick to make AC really really work, even in the hot summer!
A few years ago I decided to upgrade the AC lines to the newer PVC enclosed lines. This keeps freon from slowly seeping out of the system. As luck would have it, my AC fan gave out at about the same time.
The AC specialty shop replaced the standard squirrel fan in the 914 with a larger, flat electric fan. The results were spectacular. The output must be at least 3x higher. The car gets so cold that at times I have to turn down the fan/temp setting!!! I am posting now because every summer I marvel at the improvement. Dave |

If you mean the front condensor fan...
The VPC (VW parts corp?) A/C used a less efficient "squirrel cage" fan over the cond. The DPD (I forgot) uses a flat blade convensional fan. So you would have probably done just as well putting it the DPD unit. As for the evaporator fan under the dash, I think they are both squirrel cages. Is this the one you replaced? The PVC lines are they the same as the "barrior" type hoses used with R134a? Also has anyone thought about using copper tubing? Is this just a BAD idea? I would beld it and clamp it down so it wouldn't chaft, but does the car flex too much or something? It's just that my buddy spent a couple hundred re-doing his 930 A/C lines and I can't see putting that kind of money into my car right now. |

Well, the commonly-available copper tubing work-hardens. That's why you *don't* use it for fuel line. Anyway, if there is any flexing AT ALL it will eventuall crack at that point. I doubt ANY car, let alone a 914, is completely rigid, so the lines will flex at least some. And they will flex more where the rubber hoses or other components connect to them.
Use copper if you don't mind all the refrigerant leaking out. --DD |

Move to Miami, during a summer thunder storm, and as you take off your shirt to wipe the fog off the front window try telling me to roll down the window.
Seriously, the only reason I kept my 914 (the PO gave up on it...in my garage) was that the top came off like my old Vette. I really think the 914 is a better looking car than the 911 Targa. (>: |
