It does seem to work until something on my air-con starts to squeal, then the air-con is very weak.
![Roll Eyes (Sarcastic) :rolleyes:](./images/smilies/rolleyes.gif)
I wonder if it's a problem with just a belt, a pulley or the condensor itself.

Have you done this yet? The longer you leave it the harder it will be to convince them they didnt do it properly...RSR 555 wrote:Definately a loose belt. I would drive back and get them to check, also tell them about the intermittent issue. I suspect it's cutting in and out because the belt is loose and the sensor is picking up different RPM than the engine is really doing. You could tighten the belt yourself but really need to know the correct tension otherwise you could were out you idler pulley bearing prematurely. Also get them to make sure the inner belt is tight.. I see so many loose
Or there's crap in the system and the compressor is chewing on this and thus damaging itself. That'd be the worst case scenario.Smash1911 wrote:If they have overcharged the system it is possible too much liquid refrigerant is getting to the compressor causing it to hydraulic, causing your belt to slip. The over pressure in the system might be then causing the pressure sensor cut the compressor out. Just a guess
yes its definately loose.2nd Hand Yank wrote:^^ Ouch! I'll call up the shop soon.
I had a poke around the engine and it seems the inner V-belt is slacker than the outer one.
Is that probably the reason I'm having A/C difficulties?
...and the belts as most responders have advised?2nd Hand Yank wrote:I just did a test today...
My condensor stays on at low rpm + low engine load.
Examples:
- 70 km/h in 5th on a flat road
- 50 km/h in 4th on a flat road
- 30 km/h in 3rd on a flat road
Most likely IMO. I would check their condition and replace if needed.2nd Hand Yank wrote:^^ Ouch! I'll call up the shop soon.

I'm guessing you mean compressor. Low RPM or load wont really show you much. It's how hard the A/C is having to work to keep the inside cool. I would definately tighten the belts or replace as mentioned.2nd Hand Yank wrote:I just did a test today...

If buying new belts, just ensure you are getting the correct sizes. Don't always go off the old ones, as the previous owner may not have. There is 2 different sets available for the L.Series... with or without powersteering.
The best piece of advise I can ever give you is.. NEVER believe what supercheap say2nd Hand Yank wrote:Yes I meant compressor.
My A/C won't work at all... unless there is low RPM + low load.
It squeals like hell before quiting when it isn't low load + low RPM.
SuperCheap says
"...there is only one belt for an L Series..."
Same with other parts stores.
I have never seen a "set" for sale for my car.
Where can I find this "set?"
Thanks.RSR 555 wrote:The best piece of advise I can ever give you is.. NEVER believe what supercheap sayMost of the time they employ 16yo kids who have never worked on cars.
There is actually 4 "sets" available for the L.Series (EA82) model.
1. Inner and Outer Belt for EA82 without A/C and without P/Str
2. Inner and Outer Belt for EA82 without A/C and with P/Str
3. Inner and Outer Belt for EA82 with A/C and without P/Str
4. Inner and Outer Belt for EA82 with A/C and P/Str
When I say "set" I'm talking about the 2 front belts for the accessories (not the Timing Belts). You wont find a "set" at any store because most places sell them individually because they sell them for all models/manufactures.
I can't remember if your car comes with or without powersteering?
Let me know and I'll advise you what belts you require.
