930 Air Con

Hi Guy's

Has anyone installed new barrier hoses in their 930, a job I was thinking about doing over the winter months.

I did it last winter. It's not difficult in a technical sense, but unless you have a lift, you spend a lot of time on your back with gravel falling in your face while removing the old system. My motor was out too, so that did help a bit.

I used Griffiths and also got his evaporator, front condenser, dryer and center console vents. My decklid condenser and compressor were fine.

It was worth it to me as I now have 41 degree vent temps.

just did it with motor in.
not hard.
the big issue is trying to figure out "slack" at the ends.
also save the old dryer for fitting purposes. you don't want to leave the new dryer open to air while fitting the lines.
also don't tighten anything until they are all in.
leave the caps on the hoses until done., you don't want dirt in them

start at the evap. these are the tightest fit. run TO the dryer and comp.
run from front cond TO the dryer.
run from front cond to rear cond.
you can use any slack in the hoses in the engine bay.

its not hard. hose down the underside of the car, it will help with dirt falling in your face. I wear safety glasses for jobs like this. its not that big a deal on jack stands. I have a tall jack and 2ft stands so I get the car really hi.
I also have a spare dolly I pull around under the car with tools and bolts/clamps on it. much better than laying tools on the ground.

not hard at all, but messy and not a particularly fun job

I'm having my local Porsche specialist do my install even as we speak. Maybe I could have done it myself, but I have zero experience with AC systems.

BTW, I got the Mac Daddy Griffith system.

Smart on both accounts.

Doing a/c properly takes good ($$$) tools and a willingness to perform many, time consuming "do-overs" (this I know well! ), and Griff's gear, and customer service, is second to none.

Since I have the good fortune of living within about 20 minutes of Charlie, I did all of the install and then let him evac, charge and test it for me. Saved a bundle by doing the dirty work and got the tough part done right by the expert. Win/win, in my opinion.

Jeff, I woulda' thunk that you could have pulled a serious vacuum on the system with that super duty vac pump you have built in beneath your nose! Coulda' saved Griff some work and showed up at his shop with that bisch sucked down proper like!!!

LOL. This coming from a man whose screen name describes the injuries caused by all of his sucking!

Oh yeah, I went there.

I did mine with hoses and a new compressor from Griffiths. I removed both condensers and my evaporator and cleaned them thoroughly too. Do the seals inside the evaporator housing. There is a kit from Porsche for the seals on the outside, including the trapezoid sponge on top of the evaporator housing. Change out both blowers.

I am very happy with everything from Griffiths, including support. The 3.0 Turbo has a unique compressor discharge hose. We went back and forth to get it right so as to fit the new Griffiths compressor. They were super helpful. I enjoyed my AC all summer, but then again I live in New England. I have access to quality AC service equipment, which helps a lot, but you can save some money by changing out the hoses on your own. Be patient. Cleanliness is essential. Clean the underside of your car with a high pressure washer before you start. It will still be a mess.
