Re: Replaced compressor, failed again 9 days later. Advice sought

Thank you, I will update again once it's been inspected by someone who knows what they're doing :) Another theory I was told was that potentially the freewheel clutch pulley on the alternator is failing (not slipping properly in one direction) and putting undue stress on the compressor pulley. Or so...

Re: Replaced compressor, failed again 9 days later. Advice sought

Thanks for your analysis! This is probably the avenue I’ll take.

Those pressures were measured at idle speed though, not at 1500rpm. Can’t imagine it’ll make much difference though.

Re: Replaced compressor, failed again 9 days later. Advice sought

Just realised the pressure readings are written on the piece of paper I have!

Ambient temp: 21c
Vent temp: 5c
Low pressure S/R: 2.0
High pressure S/R: 7.5

Presumably these readings are in Bar!

Re: Replaced compressor, failed again 9 days later. Advice sought

Thanks!

So I’ve had a bit of a look around with a UV light, and the only evidence of any leakage I can see is on the LP valve, here’s a photo:

Although this is probably just where it was filled?

The HP valve had no trace at all.

Re: Replaced compressor, failed again 9 days later. Advice sought

Thank you!

So, am I right in assuming that the compressor, erm, compresses in the direction that the condenser is "first", so any debris pumped through the system by the compressor will only reach the condenser, and not flow to any other more remote parts of the system?

Thanks again.

Re: Replaced compressor, failed again 9 days later. Advice sought

Thanks again for your replies! The compressor wasn’t OEM - well, it probably was once upon a time but I’m afraid I have to admit I went for the cheapest option of a refurbed unit! I am thinking that I’ll spend a bit more on a new aftermarket one this time around - are even the cheaper ones usually a...

Re: Replaced compressor, failed again 9 days later. Advice sought

Thanks very much for your comprehensive reply. That all makes sense. The technician did state that he measured 100g of oil in the new compressor. Is it likely that there is debris in the system if its the variable vane type of compressor with a failsafe shear on the pulley? Will it still chuck debri...

Replaced compressor, failed again 9 days later. Advice sought

Hi folks, I do enjoy working on cars but AC really is not my area of expertise (or ability, since I don't have the tools to work with the gas!). The problem is with my girlfriend's car, a 2007 Toyota Auris. A while back, we noticed that the AC no longer worked. It gets used all year round with the c...
