for information.
denso repairs aircon compressors using brand new parts. so you don't have to worry about compatibility or something.
its cheaper than buying brand new ones and more safe than buying surplus ones.

based on the brochure that i have, they are:

a. quality guaranteed;
b. original and brand new shaft seals and gaskets are used
c. out of spec parts are replaced with brand new parts.

just visit their branches to inquire. afaik, they have branches in Makati, Alabang, Caloocan, E Rodriguez QC, Pasig, Paranaque, Binan and Quezon Avenue.
