Be certain to specify the model year and application of the engine. Also include a small tube of gasket sealer in the purchase. Local parts stores typically have these items in stock and may have balancer puller and installation tools available for rent.
You can also order the parts online from parts vendors. Remove the fan from the water pump. Before you remove the water pump, be certain all of the water from the cooling system has drained completely. The goal is to avoid getting any coolant in the engine crankcase once you've removed the timing cover. Loosen and remove the water pump four bolts attach the water pump to the front of the engine block.
Scrape and clean the gasket surfaces of each. Remove any pulleys attached to the harmonic balancer. Remove the balancer bolt and attach the harmonic balancer puller to the front of the balancer and tighten the center bolt to pull the balancer off the crankshaft. Remove several of the front oil pan bolts and loosen the remainder so that the oil pan can be partially lowered away from the timing cover. Remove all timing cover bolts and gently pry the cover away from the engine block. Scrape and clean all gasket surfaces.
Remove and replace the front crankshaft seal in the timing cover. Rotate the engine by hand so that the two timing marks on both sprockets are aligned. Remove the three cam sprocket bolts and slide the cam sprocket off the camshaft. Install the new chain and camshaft sprocket, making certain both timing marks are aligned at their closest point. Tip: Crank sprockets rarely fail or wear. If no damage is visible, you can save time by not replacing it.
Slide the lower timing gear onto the tip of the crankshaft, then wrap the timing chain around the lower gear. Wrap the timing chain around the upper timing chain gear, then press the upper gear onto the tip of the camshaft. Note that a metal dowel on the camshaft slides through a hole next to the center of the upper gear. Apply gasket sealer to each side of a new timing chain cover gasket, then position the gasket onto the back of the timing chain cover.
Apply gasket sealer to each side of new water pump gaskets. Position each of the two water pump gaskets onto the water pump, then press the pump into place against the cylinder block. Connect the heater hose and the upper radiator hose to the water pump and tighten the clamp on each hose with a screwdriver.

Step 3 Loosen the clamps that secure the heater hose and the upper radiator hose to the water pump with a screwdriver, then pull both hoses off the pump.
Step 5 Unfasten and remove the bolts that surround the outer edges of the timing chain cover, then pull the cover off the cylinder block to expose the timing chain. Step 6 Turn the bolt at the tip of the crankshaft with a wrench until the circular indentation on the face of the upper timing chain gear points straight down and the circular indentation on the face of the bottom timing chain gear points straight up.
Step 1 Slide the lower timing gear onto the tip of the crankshaft, then wrap the timing chain around the lower gear. Step 2 Wrap the timing chain around the upper timing chain gear, then press the upper gear onto the tip of the camshaft. Step 4 Apply gasket sealer to each side of a new timing chain cover gasket, then position the gasket onto the back of the timing chain cover.
