Toyota 13529-20900 Gear, Camshaft Sub

To remove the timing belt, start by disconnecting the negative cable from the battery and removing the coolant overflow tank and windshield washer tank. If applicable, remove the front suspension upper brace from the strut towers. Then, remove the drive belts from the alternator and power steering pump. Loosen the lug nuts on the right front wheel and raise the front of the vehicle, supporting it on jackstands. Remove the right front wheel and inner fender apron. Position the number one cylinder at TDC and support the engine with a jack. Remove the engine movement control rod and its bracket, as well as the spark plugs. Remove the upper timing belt cover and check for installation marks on the timing belt. Rotate the crankshaft pulley counterclockwise 60 degrees BTDC and remove the timing belt tensioner. Relieve tension between the camshaft sprockets and remove the timing belt from the sprockets. If necessary, remove the camshaft sprockets and the upper idler pulley. Remove the crankshaft pulley bolt and remove the pulley. Remove the lower timing belt cover and slip the timing belt guide off the crankshaft. If reusing the belt, check for a mark on the belt adjacent to the drilled mark on the crankshaft sprocket. Remove the no. 1 idler pulley and plate washer using an Allen wrench. If needed, remove the crankshaft sprocket. Finally, remove the lower sprocket retainer.

At the start, remove the engine's ground wire. Pull down the fluid tank and windshield spray tank. On Solara models, take off the four area nuts and the upper front suspension connecting brace. Use these steps: remove the drive belts from your alternator and power steering pump, loosen only the right front wheel's lug nuts, raise the front end of the vehicle, place it on jack stands to securely support it, set the parking brakes, block the rear wheels, and take off the right front wheel. After removing the lower fender on the right side of the engine bay, manually turn the first cylinder to its peak opening point, raise the engine on the jack from underneath, and take off a bar that keeps the engine from shifting. First, pull out the three spark plugs on the engine. Then remove the cover, the upper timing belt gasket, and timing belt. Make sure the camshaft pulley's two key marks match before you loosen the timing belt tensioner. Lower tension between the rear and front camshaft sprockets first, then pull the timing belt off from both camshaft sprockets, and take off the camshaft sprockets if needed - loosen the sprocket bolt while holding the camshaft with a wrench. Take off the upper idler pulley, the crankshaft pulley bolt, and look to see where the crankshaft's top position is. You should be able to take the crankshaft pulley off with hand strength, but if not, get two prybars to remove it. Take off the lower belt cover and gasket, put the crankshaft instruction through the timing gap, and look closely for a factory dot on the belt that matches the marked spot on the crankshaft gears. To find out if the idler pulley and plate washer need replacing, take off the idler pulley and plate washer. If they look worn or damaged, remove the crankshaft sprocket carefully. Look for oil leaks on the belt tensioner, check for moisture inside the valve, measure the pushrod tip, and make sure the idler pulley turns without trouble. Wipe the timing belt area clean, correctly position the crankshaft timing sprocket keyway over the crankshaft key, and put the sprocket into place. Before fitting the idler pulley to the car, apply thread-locking substance to hold the bolt in place. Then place the idler pulley and its washer, and screw in the bolt. Start putting the timing belt on at the crankshaft sprocket, push a belt guide over the end of the crankshaft, and put on the lower timing belt cover with its gasket. Put the crankshaft pulley onto the shaft and attach its bolt. Hold the crankshaft still to keep it from moving. Put the top idler pulley into place, tighten the bolt, and make sure it spins effortlessly. Place the front camshaft sprocket, and attach its bolt before double-checking engine timing. Attach the rear sprocket to its bolt, and check if the timing marks align properly. Gently rotate the front camshaft sprocket until the belt fitting imprint lines up with the camshaft timing pointer. Slide the belt onto this sprocket. Feeding the belt around the rear sprocket, you push down on the timing belt tensioner rod, put the tensioner in place, and secure its bolts. Rotation the crankshaft two full circles while checking the timing markers. Replace the bracket for the engine movement control rod, put back the upper timing belt cover and its gasket, mount the rod with the brackets, and tighten all the bolts firmly. Put back the parts in the opposite order you took them out.

Disconnect the cable from the negative battery terminal.
