Do not rotate the camshafts or crankshaft when the timing belt is removed or damage to the engine may occur. Begin by removing the timing belt. Rotate the crankshaft counterclockwise until the crankshaft sprocket is three notches BTDC to prevent engine damage if the camshaft sprocket is inadvertently rotated during removal. While keeping the camshaft from rotating, remove the camshaft sprocket bolt, then use two large screwdrivers to lever the sprocket off the camshaft. A strap-type damper/pulley holder tool is recommended for this procedure, but if the old timing belt is not being reused, wrapping a piece of it around the sprocket and using a chain wrench can also hold the sprocket in place. Carefully pry out the camshaft oil seal using a small hooked tool or screwdriver, taking care not to scratch the bore or damage the camshaft, as damage will cause the new seal to leak. Clean the bore and coat the outer edge of the new seal with engine oil or multi-purpose grease, also lubricating the seal lip. Using a socket with an outside diameter slightly smaller than the seal and a hammer, carefully drive the new seal into the cylinder head until it's flush with the face. If a socket isn't available, a short section of pipe can be used. If engine location makes it difficult to use a hammer, fabricate a seal installation tool from a piece of pipe cut to the appropriate length, a bolt, and a large washer, placing the pipe over the seal and threading the bolt into the camshaft to press the seal into the bore by tightening the bolt. Install the camshaft sprocket, aligning the pin in the camshaft with the hole in the sprocket, and using an appropriate tool to hold the camshaft sprocket, tighten the camshaft sprocket bolt to the specified torque. Finally, install the timing belt and run the engine to check for oil leaks.

Do not rotate the camshaft(s) or crankshaft when the timing belt is removed or damage to the engine may occur. Begin by removing the timing belt. Rotate the crankshaft counterclockwise until the crankshaft sprocket is three notches BTDC to prevent engine damage if the camshaft sprocket rotates during sprocket bolt removal. Hold the camshaft sprocket and remove the camshaft sprocket bolt; using a strap-type pulley holder tool is recommended for this task. If unavailable, two large screwdrivers can be used to pry the sprocket off the camshaft, or the valve cover can be removed to access the camshaft wrenching flats. Next, remove the idler pulley and the bolts holding the rear cover to the engine block and cylinder head, then take off the rear cover. Pry out the camshaft oil seal carefully to avoid scratching the bore or damaging the camshaft, as damage will cause the new seal to leak. Clean the bore and coat the outer edge of the new seal with engine oil or multi-purpose grease, lubricating the seal lip. Use a socket with an outside diameter slightly smaller than the seal and a hammer to gently tap the new seal into place with the spring side facing inward, ensuring it is flush with the face of the cylinder head. If a socket isn't available, a short section of pipe can be used instead. If space is limited, fabricate a seal installation tool from a piece of pipe, a bolt, and a large washer to press the seal into place. Afterward, install the rear timing belt cover and idler pulley. Install the camshaft sprocket, ensuring the pin in the camshaft aligns with the hole in the sprocket, then hold the camshaft sprocket and tighten the sprocket bolt to the specified torque. Finally, reinstall the timing belt and run the engine to check for oil leaks at the camshaft seal.

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.

Install the rear timing belt cover, tensioner pulley/bracket, idler pulley, and tensioner pulley as applicable.

Carefully pry the seal out with a small screwdriver, ensuring not to nick or scratch the camshaft or seal bore, as damage will cause the new seal to leak.

Carefully tap the seal into place using a large socket or piece of pipe and a hammer. If a suitable socket is unavailable, tap around the outer edge of the seal with the large end of a punch, taking care not to cock the seal in the bore.

Reattach the inner timing belt cover.
