Air con compressor: 11720-77A01 Alternator: 11720-42L01 Power steering pump: 11950-58S01 Cam belt: 13028-20P25. My car used to squeal real bad especialy at high rpm. i changed all 3 front belts and have not had any trouble. Repco can provide Dayco equivelants to the nissan belts cheap around $15 each, cam belt around $100 for the gates racing belt. Your cam belt should be done at 100 000 km.
