Hello everyone,
i replaced a Chinese made Denso AC compressor on my Honda CrV and it’s working good but I hear some noise when the ac is off. My question is does anyone has the same experience with this Compressor, is it common?
do I need to check anything else?
Thank you
Happy new year to everyone of you technicians and experts , and participants

Are you sure the noise is coming from the compressor? Is the compressor engaged when the noise occurs? How old are your fan belt and pulleys?
The noise comes as the ac is working and the car is on reverse , sorry there is no noise when the AC is off , what do you think is the problem?
It could be pretty much anything that's run by the fan belt since the compressor stresses that entire system when it engages. If you take off the fan belt you can rotate all the pulleys by hand to feel for roughness in the bearings. The belt itself is also suspect if it is old, as would be the tensioner if it's weak. A mechanic's stethoscope may help you pinpoint where the noise is coming from.
