Davehods Posted June 25, 2021 Report Share Posted June 25, 2021 Hi All. I have just had a mobile aircon guy check over my aircon as it was not blowing cold. He has done a pressure test up to 177PSI and found no obvious leaks in the pipework/condenser etc. However, there was a leak via the dash vents which he has attributed to the Evaporator. He had never fitted one to a Boxster and reckoned that it was probably a dash out job. Have any of you replaced one and if so how big a job was it? Many thanks in advance...

Davehods Posted June 25, 2021 Author Report Share Posted June 25, 2021 Hi @Gutley thanks for the link….if I am honest that link scares the bejesus out of me 🤣 I can imagine a) never getting it all back together and b) the dash rattling for ever more!

Davehods Posted June 29, 2021 Author Report Share Posted June 29, 2021 (edited) Just out of interest...I have been quoted 2 days labour to fit the evaporator! Confirmed by my man in the garage that it is a complete dash out job. Shame as the rest of the system is leak free with newish condensers and pipe work.

Bradders59 Posted June 29, 2021 Report Share Posted June 29, 2021 Set a weekend aside, two weetabix for breakfast, get your spanners out and get stuck in. Its only nuts / bolts and block connectors. Not brain surgery. 👍 1 Quote Link to comment Share on other sites More sharing options...

Just be methodical and take pictures as you go just in case you forget what goes where. 1 Quote Link to comment Share on other sites More sharing options...
Davehods Posted June 30, 2021 Author Report Share Posted June 30, 2021 Hahahahaha...it is a lot of nuts and bolts! I would not have the time to set aside for a job of that magnitude, playing with cars is in competition with many other activities (mainly involving horses) and at the moment it is my daily driver having handed company car back. I think it can sit on the back burner for now...I'll just keep the roof down! Quote Link to comment Share on other sites More sharing options...
Sanky Posted July 2, 2021 Report Share Posted July 2, 2021 Is the evaporator different to the heater core? Quote Link to comment Share on other sites More sharing options...

Yes but both live in the same heater box. I purchased Dave's car and the dash is currently stripped out. As above, this is not a quick job and I would not recommend anyone taking it on without fully understanding what you are doing. 2 days is good going.

Toddie Posted August 6, 2021 Report Share Posted August 6, 2021 Odd a mobile guy changed my evaporator & the heat exchangers & vacced it out, pressure tested it, and regassed it in about 2-3 hours. Quote Link to comment Share on other sites More sharing options...

Fingers crossed this was indeed the issue Will keep you posted I really hope it is the evaporator at fault after all the work you have done. Just in case, look around for oil misting on as much of the system as you can see (especially the high pressure side) and have it pressure tested with nitrogen, before putting it back together. Good luck Quote Link to comment Share on other sites More sharing options...

Good luck Really kind of you, thank you. It is indeed a big job, The dash removal itself is not to bad but then the scuttle panel has to come apart to disconnect the heater matriculates etc etc Finally the heater box itself, it is a tight fit tbh but I am hoping I have done the hardest part. I have a mobile AC guy out next week and he will test etc 🤞 If I were booking this job in as with other work, I would probably say 2-3 days ish 1 Quote Link to comment Share on other sites More sharing options...
Davehods Posted August 7, 2021 Author Report Share Posted August 7, 2021 @TROOPER88 the guy had look at it was 100% it was the evaporator! Sounds like you have worked bloody hard on this. Funnily enough my ‘new’ 987s has no aircon at the moment either 🤣 Quote Link to comment Share on other sites More sharing options...
GmanB Posted August 7, 2021 Report Share Posted August 7, 2021 Probably a silly question, but why do you need to have operating air con on a convertible car in the UK? It's 30 celsius + for approximately 1 week of the year, other than that you have a roof to put down or you just need the heater for 9 months of the year! 1 Quote Link to comment Share on other sites More sharing options...

My brother took your view & didn't bother to replace the condensers. Now that I own the car, the aircon is fully functional. It just doesn't sit right when something isn't working. I do find it more comfortable when I can control the environment in the car, especially on a longer run. 3 Quote Link to comment Share on other sites More sharing options...
