Regassing aircon

[adpsimpson]

Has anyone had any problems regassing the aircon in a 2nd gen? It's working, but was pretty feeble in the summer past and definitely going to want it in good working order where we're going.

Do you know what type gas is in there now, R12 or R134a?

If it's the original R12 system then it can't (legally) be re-gassed.

Seem to remember there was tonnes of posts about the gas last year, sorry dont have the time to weed through them...at work.............

If the system is done properly they dont just regas it.
Don't they recover the old gas and dispose of it properly, vac the system, check for leaks then refill with the newer gas?? Or is it now illegal for them to recover the gas? or cant the old system take the new gas?
Usually a local mobile guy that goes around most areas should be around Ł45-65 I would think. (unless disposing of the old gas costs more)

Think the system has to be re-done to work with the new gas...

Only if the system has been converted to R134a.

Correct, plus the newer type fittings.

Or is it now illegal for them to recover the gas?
Not if they're a professional outfit, but I doubt any Surfs will still have any of the old gas in their systems, it would have all evaporated by now.

or cant the old system take the new gas?
New gas won't work in the old R12 system.

Thats just a basic re-gas price. Updating the system costs nearer
Ł200.

See if you can get someone to put in some r413a.
Might be cheaper, this gas will still mix with the mineral oil and carry it around the system.

I had a quote of Ł130 last autumn to change over from old gas, full clean out, check for leaks, replacement seals where necessary and re-gassing with currently legal gas. Didn't get it done in the end because the air con rads had been removed from my Surf and I can't afford to replace them!

If your system can take the newer system, you can buy recon refill in a can, which screws onto the input nozzle.

I did it in the war departments' freelander, and it worked fine.

Not all good news... How would I find out what gas is in it, whether it's had the conversion, etc? Another unexpected cost if we need to get the conversion done.

If it's 134a then they are usually 'push' on type fittings. If it's R12 then it's a 1/4" flare type screw fitting.
It should say on a plate somewhere.
As previously said, if it's 134a then you can buy a can and put it in the low pressure (bigger pipe) yourself.
If it's R12 then you either.
get it converted to 134a (seals oil change etc)
fill it with R12 (if you can find someone with some)
fill it with a 'drop in' replacement (that will work with mineral oil etc)

When adding refrigerant to a system where a leak is suspected then a thorough leak check should be undertaken of the system.
You can do this with the engine off, spray all Air con connections/pipes etc with a soapy water solution.
Of course this check can only be done when there is gas in the system.

Thanks. Where are the fittings, and where would there be an info plate? It's a 3.0 2nd gen.

There are some pictures of an R12 compressor.
I've just been out to have a look but the Surf's not there.

R12 ports are dark red and grey.

R134a ports are red and blue.


If it's been converted there should be a yellow sticker somewhere under the bonnet stating it.

What year did Toyota stop using R12?
