Toyota 13568-09041 Belt, Timing

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.

To begin the removal process, start by disconnecting the negative battery cable and ensure the rear wheels are blocked while the parking brake is engaged. Loosen the lug nuts on the right front wheel, raise the vehicle, and securely support the front on jackstands. Proceed to remove the right front wheel and fender apron seal. Following this, remove the coolant overflow tank and the spark plugs and drive belts. Take out the alternator and its bracket and support the engine from beneath with a jack (using a wood block to avoid the oil pan drain plug). Remove the right engine mount and engine support rod. Afterward, remove the upper timing belt cover screws and pull up the wiring harness, then remove the upper (no.timing belt cover and gaskets. Ensure the number one piston is at TDC on the compression stroke and verify alignment between the small hole in the camshaft pulley and the TDC mark on the cam bearing cap. Optionally, apply match marks on the sprocket and belt if reusing the timing belt. Loosen the upper (no.idler pulley set bolt and unhook the spring to slip the timing belt off the sprocket. If the camshaft sprocket requires removal, hold the rear camshaft with a wrench and remove the bolt. Remove the crankshaft pulley bolt, secure the engine from turning, and use a breaker bar and socket to loosen and remove the pulley. Proceed to remove the lower (no.timing belt cover and gaskets, slipping the belt guide off the crankshaft if needed. If reusing the timing belt, apply match marks on the sprocket and belt. Slip the timing belt off the sprocket and remove it. Inspect the idler pulleys for smooth operation and the spring for damage, and assess the belt for cracks, wear, or damage. Replace the timing belt with a new one if wear or damage is evident or if there are concerns. When installing the new belt, ensure the timing marks on the camshaft and crankshaft are correctly aligned. Reinstall idler pulleys and the tension spring, check timing mark alignment again, and fit the timing belt onto the appropriate components. Slip on the belt guide with the cupped side facing out and reinstall the lower timing belt cover and crankshaft pulley, verifying TDC marks. Place the timing belt over the camshaft sprocket while maintaining tension on one side, loosen the upper idler pulley bolt, and allow the spring to apply pressure. Slowly turn the crankshaft clockwise until the marks align correctly, then tighten the idler pulley. Rotate the crankshaft two revolutions and recheck the timing marks. If they align as required, reinstall the remaining components in reverse order, paying attention to gasket material on covers if necessary. Finally, run the engine to verify proper operation.

Remove the drive belts from the alternator and power steering pump.
