my truck recently got lauder its only in the morning when its cold out it sounds. like its comming from the intake?? and its also alost faster in the morning then in the afternoon when its warm outside is that just because the weather? its a day and night diffrence and my belt recently started sqeaking ive replaced it before about 10,000 miles ago because of the sqeaking it just started again. does it maybe need to be tensioned??
