Do not rotate the
Camshaft(s) or crankshaft when the
Timing Belt is removed to avoid engine damage. Begin by removing the timing belt cover and timing belt. Rotate the crankshaft counterclockwise until the crankshaft sprocket is three notches BTDC to prevent damage if the camshaft sprocket is inadvertently rotated during removal. Use a strap wrench or a chain wrench, with shop rags to protect the sprocket teeth, to remove the camshaft sprocket bolt, then lever the sprocket off the camshaft with two large screwdrivers. Next, remove the timing belt tensioner assembly and the upper, rear timing belt cover, noting that 2001 and 2002 models with hydraulic tensioners have a timing belt pulley assembly and a separate tensioner. Carefully pry out the camshaft seal, ensuring not to nick or scratch the camshaft or seal bore, and clean the bore before coating the outer edge of the new seal with engine oil or multi-purpose grease, also lubricating the seal lip. Use a socket with a slightly smaller outside diameter than the seal to gently tap the new seal into place, ensuring it is installed squarely and to the same depth as the original; a short section of pipe can be used if a socket is unavailable. Install the upper, rear timing belt cover, followed by the timing belt tensioner assembly, torquing the bolts appropriately. Align the pin in the camshaft with the hole in the camshaft sprocket during installation, using an appropriate tool to hold the sprocket while tightening the bolts to the specified torque. Finally, reinstall the timing belt and run the engine to check for oil leaks at the camshaft seal.
