Squealing in Timing Cover Area on Cold Startup on Mazda Protege

The timing belt tensioner pulley may make a squealing noise from the timing cover area on cold startup. An updated tensioner with a thicker mounting bracket to eliminate vibration may be needed to solve the problem.

My car usually squeals during a cold startup. I just replaced the belts and the squealing persists. From reading this, I am now suspecting that its the timing belt.
