If you hear light squeaking sound during cold start its probably the fanbelt as the sound will go off once you drive about 3-4 minutes.Better to change those quality Japan type of belt cause most Campro models like Gen2,Persona,Saga Blm and first batch Exora cps got only half layer of cover under the fanbelt itself thus water will easily went in during raining when u drive.Those mitsuboshi type belt is Malaysia made not Japan thus the quality is so so.As for my saga I did change to a better Japan type in 2011 and its still working fine till now.Now my 2010 Exora need to replace Liao.
