I have a 2006 rx330 with belt squeaking noises on after warming up for say 10 mins on cold mornings, while reaching home I could hear the noises on cold days, the outside temperatures usually 35 to 40 F
happens. While driving no noises, only happen on cold days when temperature is above 50 no problem. what do the experts think, should I replace the belts, how many belts are involved ? Tensioner problems ? thanks

Could be either or both of the belts (there are two separate drive belts). Check the slack, they could just need to be tightened up. It could be the tensioner(s), and if none of the above fix the problem, check for pulley alignment and ensure all bearings allow proper movement.
