Opel meriva 1.6 AC compressor replacement

Well done ,is it the same way to replace it in zafira b

Excellent oil choice, Errecom's PAG 46 is the closest to the OEM oil. Most shops use PAG 100 or Ester and that's not good. However, two months ago i replaced the same compressor model on my Vauxhall Agila A car and filled the oil through the drain hole located right behind the clutch. That way, nothing spills out, and it gets straight upon the internal swashplate mechanism where it's really needed. Two months have passed by and it's still alive and kicking. Can also tell you that if the condenser/radiator fan (whatever is responsible for blowing air through the condenser) has a weak/worn electric motor, this compressor will become really noisy.

Would the oil be the same for the Astra H 1.4 2006?

@@jeffersonelias81 Yeah. You can safely refill that car's AC compressor with Errecom PAG 46 oil. The original factory fill oil spec is an Idemitsu double end capped PAG 46 by the way, but Errecom product is totally on the same level. In fact i flushed a system and fit a new Delphi CVC compressor two years ago using this oil as the system's oil charge and it's still running quietly and smoothly.

Great, thanks for your reply. Can't seem to find the oil online, would you have a link? Also, when compressor replacement is done, won't the regassing process add oil to the compressor anyway? Or it it important to oil it first as you did in the video? Just trying to understand as I've heard they would do so. Thank you

@@jeffersonelias81 Ebay->Errecom PAG 46, or Google for the same. When you replace the compressor you're supposed to flush the entire system and remove the oil from the other components by means of a suitable solvent. Or, at the very least, you're supposed to drain the oil from the old compressor and add the same drained amount back to the new compressor, but that's not recommended because the leftover oil in the remainder of the system can be contaminated, or simply degraded and no longer able to lubricate the compressor properly. Adding the oil back through the regassing machine isn't correct when dealing with large amounts of oil and compressor replacements because the compressor needs to have enough oil inside when it runs for the first time. So all in all the best course of action is to flush all the parts of the air conditioning system and pour the entire system charge inside the new compressor (through the drain hole on the compressor's body), install the compressor on the car and manually rotate the clutch hub (the shaft has to rotate) 10 times so that the oil is moved around the compressor, then charge the system with refrigerant. Did all of this with my car, 2 years have passed and the new compressor is performing perfectly

Fantastic. Thanks for taking your time to write this. I am doing it as a DIY job, do you reckon it's possible without this machine? I mean, to flush the system you'd need the machine right? Also, how much oil in ml would the compressor take? Not clear in the video when you're measuring it. Thanks pal!
