On my classic uk turbo i have a/c (needs gassing if i wanna keep) but doubt i will ever bother using as in the sort of bloke who has to drive with my window down. Is it worth the effort to remove the pump ? For weight and just not having it sitting there for no good reason ?

Funny enough I keep looking at mine and thinking about taking it out, pump went last summer I cut the belt off and never really got round to replacing it. I do like the aircon but doesn't bother me too much either.

i like the idea of air con but i'm the type of guy that likes to have the windows open so the world share share in my music so don't see the point in having it hence my wagon didn't come with air con and i'm quite happy with that as for how to remove it i'm not sure but i'm sure someone will be along to help soon enough ;)

My Outback aircon was a tad feeble when I bought the motor.

After scaring myself with a main stealer's quote to service and regas I started to look into using a DIY regas kit.

Got one for £25 delivered complete with charging hose and pressure gauge :).

Followed the idiot proof instructions and now my Doris is complaining it blows too cold.

Took 20 minutes from start to finish and its still going strong two weeks later.

Got the kit from these peeps although their prices seem to have gone up during the hot weather.

I have no affiliation with them just saying it worked for me and saved a bundle of beer tokens as well.

Haha funny this thread should appear now. Don't know weather to get rid of mine or re gas

I've been to Halfords and ats today to see how much they'd charge to re gas mine. £49 & £45 respectively no test though just gas. Seems like the £80 Bits subaru want at the mo good value as they'll pressure test and change any seals and re gas. Just wondering how lomg the weather will last,

Subaru quoted me £299 hence the diy job. For £80 quid I'd get them to do it.

Wow ! Must have been a special offer big sign above the parts counter last week when I went in.

Did you take any pics when you were doing yours ? I'm half tempted to have a go myself but got a bit confused with the high and low bobbins.

Only wnat it done for the babies benefit as I prefer windows down too

Not sure how the car would start better lol.Do you leave the aircon on when you start the car in the morning lol.I do agree with the other person post about better airflow through the rad if the aircon rad wasn't there

Mine is totally useless too....need to establish if pump has failed first, but this seems a good idea and has been added to the list to do [emoji106]

Easy way to check compressor runs is to disconnect the power cable and apply 12v so the compressor clutch operates. If you hear a loud clacking then it is working. If the engine is running when you do this the compressor should turn when voltage applied.

Next find the aircon gas pressure switch and disconnect it. If the system is low on gas then it stops the compressor turning. The connector will have four wires. You need to short out one of the two opposing pairs to fool the system into thinking it has enough gas pressure. Imagine the wires are located north south east and west on the connector you need to short either north and south or east and west and the compressor should kick in if all fuses are OK. One of the pairs is the coolant temp and shorting them mimics coolant overheat so the compressor wont spin. If the compressor still wont spin then check the aircon relays.

 

Once you are happy its not an electrical or compressor problem you are ready to regas.  Find the low side connector which on my Outback is next to the bulkhead with an "L" on the dust cap. The regas hose wont fit the high side as it is slightly bigger. Follow the instructions on the can. Basically purge the connecting hose, connect it, add gas with the engine running and air con set to max. If the compressor is running then good, if not it will kick in once the pressure gets to about 20psi. You are looking for a stable pressure of 25-45psi low side. Dont go above 45psi under any circs. Assuming you dont have a major leak it should take about 10-15 mins for the low side to stabilise with the compressor running. Turn the compressor off and the pressure should gradually start to climb towards 90psi. This is normal so dont panic. Restart the compressor and check the pressure. Once it stabilises somewhere between 25-45psi you are done and should have ice cold air coming from the air vents. Disconnect the regas can and fit the dust cap. Just a warning if you do manage to connect the regas can to the high side it will likely go pop if the compressor kicks in as most aircon systems run at 250-300psi high side. Also wear gloves and eye protection as the gas will freeze skin and eyeballs virtually instantly if spilt. I'm no expert so as in all things you do this at your own risk should you decide to have a go. It sounds more scary than it really is though.

Holy crap lol and there's me thinking it was a DIY job for relative novices such as I haha [emoji33]

It really is easier than it sounds. Plenty of how-tos on youtube which may explain things better than me.

I just like having a bash myself before splashing the cash.

Stripped and rebuilt my first engine when I was 14. Gearbox shortly after that. Only way I could keep my beloved Escort Mexico on the road all them years ago. Wish I'd kept it as I'd be minted now. They go for silly money even for a shed these days.
