There is only one serpentine belt on the 9th Generation Corolla, 2003 to 2009 model years, all have the same engine, the 1.8Liter 1ZZ FE and has spring loaded tensioner, the only reason the belt can become 'loose' is the tensioner has become weak or broken. Yes, inspect it, but Toyota has no set mileage interval for replacement. It will last at least 60,000 miles or more. There is an exception to the 9th Generation, the XRS Trim was available for the 2005 and 2006 model years with a High-Performance 2ZZ GE 1.8Liter, but still with a single belt.
