I think his short cut is to practice on a half dozen other cars first!

I think the quickest I've read about is 1-1/2 hours by two guys (DI.net I think). Not sure I'd want it done that fast on my car - maybe a few screws were left out. :)

But 5 hours by Bob - I'd trust.

Well that was the either #5 or #6 so I have loads of pracitce :( Good news is I know exactly where every clip, screw, harness, ground, is and what tool it takes to do the job. Seats stay in as does the glove box, console. Once the HVAC box is out, again the little tricks to open it up are familiar ground. Once the evep is back in, system goes on vacuum. While I button up the dash and interior and refill coolant etc, system has been in vac for an hour or so. Charge it and enjoy. ( when I am on a mission, lettle to nothing slows me down. Ask Keith :lol: )

I used to do them in 5.5hrs but turned over the reigns to my brother who can do them in 3. I haven't told him he is doing it on mine soon!

So I went to a shop to get pressure readings out of A/C system, and no wonder, 0 psi. They found no obvious dye streaks or leaks either. Guess why I posted this to a EVAP-thread.... :shock:

Updated this thread for my 2 300M's. My 1999 has no record of the evaporator being replaced, and the dash has no signs of removal. My "new" 2002 Special however has the telltale A/C Oil smell that indicates I will be pulling my first LH Dashboard. It's upsetting that there was that change in the 2002 model year because I have an older style evaporator in my parts stock because I misdiagnosed my 1995 (needed a condenser not an evaporator).

My 99 has 127k on it. I remember the evap going out at around 70k. At that time we paid a mechanic to replace it, but he/they left out a bunch of screws and cracked some plastic. From then on I vowed to do my own work, since we tend to do better work when we ourselves do it. It went out again just recently at 120k. I did all the work myself, replacing the whole system ( comp, lines cond, actuators.) The job took all weekend and was actually quite pleasurable since I enjoy auto repair. It cools great and this is the last time I have to repair the system.

All week end is right! I see these speed fix in 5h or less and that means serious focussed business!
I am at my 4th evap work and I may be the slowest of all of ya!
Day1: rip appart the whole think, clean every nooks and crany then go get drunk from exhaustion.
Day 2: dismantle the HVAC clean it up to a point of being able to eat from it and put new parts then go get drunk to forget the mess I cleaned.
Day 3: put everything together, clean more and when done go get drunk to celebrate.
Day 4: in bed all day with massive headhache from drinking.
So that is a long weekend.. :D
