2012 Yaris a/c pipe leak

Recommended Posts

Hi, I have found a leak on the liquid pipe in my engine bay. Can anyone recommend a source of aftermarket pipes or is a main dealer the only option?

I'm fairly certain the car is a NSP130 (2012 Yaris 1.3 5dr CVT) and part number 88706a.

Thanks.

If you are certain that there is a leak on one of the air con pipes (and in which case the air con will not be working at all at this time as all the pressurized refrigerant will have escaped to the air) then its either a dealer or independent air con specialist.

Are you 100% certain about the leak and the pipe? If the air con works its not what you think it is.

Hi, there is definitely a leak on the liquid pipe. I'm quite happy to make the repair myself but need the spare part to fit to the car.

Only original parts from a dealer.

At the risk of sounding daft, can you tell us exactly what pipe you are referring to?

The aircon system has two obvious 'pipes' both of which connect to the compressor and both of which carry the same refrigerant as it circulates around.

Is it like an oily leak you see? or do you mean something else.

But it's as a gas going to the condenser and liquid from there to the evaporator inside the car. So the liquid line would be the latter pipe.

Both pipes at the compressor will be gas.

I'm a bit curious about this liquid leak - The air con gas will only turn into a liquid when very cold or pressurized - Under normal atmospheric pressure and temperature it will revert to a gas.

I don't know of another source of the AC pipes apart from Toyota, but a good AC specialist can fabricate some, usually using AC-grade rubber pipes rather than the normal aluminium ones though.

When you say you can change them yourself, do you have something to remove all the gas first and put it back again afterwards?

Yes, the compressor does not pump liquid... I didn't go into the 'state' of the refrigerant at various arts of the process... what I was really trying to get at is simply 'what is actually leaking'?

Once a leak in the pipework occurs the liquid refrigerant will vent and boil off to the atmosphere very quickly indeed without trace and the only clue would be some of the compressor oil that get pulled out with it. 

As @Cyker says:

So am I.

I also wondered if the op was seeing the drain tube (pipe) dripping and thinking there was a leak.

The OP didn't say it's a liquid leak.

The liquid line pipe. Like he said.

It's hard to tell on these forums whether a new entrant knows what he's talking about, but I try to at least begin by believing they might.

Ah indeed they didn't! I wonder what the nature of this leak is...
