Replacing a Hyundai's timing belt requires a set of wrenches and sockets, as well as a screwdriver and a torque wrench. The process requires the removal and loosening of many components in the engine that get in the way of replacing the engine.
Remove the negative battery cable. Loosen the accessory drive belt tensioners and lift the belts of the pulleys. Remove the water pump and crankshaft pulleys as well as the timing belt cover. Rotate the crankshaft until the timing marks are aligned.
Loosen the tensioner pivot bolt and the tensioner bolt. Lever the tensioner toward the water pump with a screwdriver, remove the old timing belt and tighten the tensioner bolt just enough to hold it in place. Place the new timing belt in, working counter-clockwise starting at the crankshaft sprocket. Realign the timing marks once the belt has been installed by turning the crankshaft sprocket slightly counter-clockwise.
Loosen the tensioner bolt and allow it to put tension on the belt. Rotate the crankshaft until the marks align again. Loosen the tensioner pivot bolt and tensioner bolt again. After this, tighten the tensioner bolt and pivot bolt to about 17 foot-pounds of torque. Check the belt by applying about 11 pounds of force on the belt between the crankshaft and camshaft sprockets.
Align the belt and crankshaft one more time, and reinstall the parts. Once installed, tighten the crankshaft according to the model of the Hyundai; about 115 foot-pounds for models from 1995 to 1996, and 107 foot-pounds for models from 1997 to 2000.
