I've had my car put in for air con check twice. They gased it up and second time cleaned the fins(??) Still not as cool as my old (99) Hilux and runs warmer when standing still idling. Any advice please. It also takes a long time to cool sufficiently. Car only done 80,000kms.

Well i have had holdens ever since my ass sat in one for my licence..Had them all my life but you will not see my ass in one again as an owner..

I believe from new if you get a good one your troubles wont start for about 4-5 years then its all down hill..My brother in laws Rodeo is three or four as a guess and the central locking system is crapping out,he has had it since new..




Cheers

I reckon it's something to do with the "new" environmentally friendly gas used these days.

Older vehicles kept the temp right down.

Check that your hot water switch completely closes.
As well if the car aircon has been serviced they are required to ensure that it reaches 5 celsius at 1500 rpm.
If they haven't done this then ask them to recheck, and fix the problem

Hi Bushtrek. Where is the 5 degrees measured? Would that be in the cab with recycled air? Who says they have to do this so I can quote? Thanks for your advice.

If it needed gassing up then doesn't that mean it has a leak? As far as I know air cond units don't "use" gas. ? take it to another air cond mechanic for second opinion. Something sounds suss.

Thanks all. The older Hilux had the same gas system. I'll check heater lever and get them to check temp.

Twinkles, the new gas they have to use nowadays isn't as good as the older (I think R12) gas they used to use a few years ago.
Unfortunately, but that's the way thinks are going now.

I was told not so long ago that the next generation of engines we get in our trucks, you will be able to wipe a white cloth inside the exhaust pipe and not get it dirty, that's how good the emission control will be.

Downside is that we will use more fuel. Work that out.
At 1.6 Kms per litre at the moment, it doesn't sound good!!

the newer refrigerants in a r12 system is a little less efficient..

but in systems designed for r134a the aircon system should be just as effective as any other..... if designed correctly of course and one assumes they have been

cant help you but i can tell you 2 things
1) new gas works just fine
2) when you take your vehicle in with dodgy aircon the first thing they do is regas it wheather it needs it or not and give it back - hopefully you wont return.
you need to take it to an aircon repairer not a regas merchant.

i took mine back and spelt it out that i specifically said i want the aircon fixed not regassed and any further repairs there wasnt a hope in hell i was paying for another regas.
.... i got it back fixed and even thought the gas would have had to be purged there was no regas charge

We had problems with our 80 series, they ended up putting a dye in the system. after a week or so they had a look at night and that found the leak. the dye shows up under UV light and is best viewed at night....

While it is true the new refrigerant is not as good as the old R12, it is still very effective -- certainly keeps the cabin very cool despite 40° outside.

If the system was "regassed" as claimed, that indicates the old gas leaked out. And that means an existing leak which will allow the new gas to go the same way. Regassing is not good enough -- the source of the leak must first be found and repaired.
