The past few days when I start up my car there is a high pitch squeak/squealing sound (not continous either) but is 'coming more' often than 'going'! Almost sounds like it could use some WD-40, but I'm sure that isn't[ as simple.... Could it be a timing belt? How or when do you know?
Thanks a bunch!

If you do replace the belts, then be certain to change the tensioner and idler pulleys. I had the same issue and I just had to replace the pulley, not the belt.
