Accepted Answer

Prepare tools and disconnect the battery's negative terminal. Remove the drive belt, alternator, valve cover, ABS actuator, right front wheel, and drain the cooling system. Position the number one piston at TDC, aligning the timing marks. Remove the crankshaft pulley/vibration damper, passenger-side engine mount, drive belt tensioner, and crankshaft position sensor. Remove the oil pan, main wiring harness junction, and timing chain tensioner. Inspect all components for wear. Clean the timing chain cover and apply RTV sealant. Reset the timing chain tensioner to its "zero" position, lubricate the O-ring, and install it. Reinstall the crankshaft pulley/vibration damper and set the chain tension. Confirm TDC alignment and tighten the timing chain cover fasteners before proceeding with the reinstallation process in reverse.

Question 4

How to remove the Timing Chain and Sprocket on V6 engine on 2007 through 2015 Toyota Avalon?

Accepted Answer

Caution should be exercised during the removal process of the timing system, as any mistakes can lead to severe engine damage. It's advisable not to attempt this procedure without substantial experience in such repairs; consult an expert if uncertain. To initiate the removal, it's recommended to remove the engine/transaxle assembly and the drivebelt, including the drive-belt tensioner and idler pulleys. Set the engine to TDC and remove the crankshaft pulley with care to prevent any damage. Proceed to remove the timing chain cover bolts and the water inlet, along with its O-ring and gasket. Afterward, detach the timing chain cover, ensuring caution in specific removal spots to prevent cover damage. Remove the old crankshaft seal meticulously. Verify the No. 1 piston's position, setting it near TDC on its compression stroke. Ensure alignment of the timing marks on camshaft timing sprockets and the crankshaft sprocket. Following this, manipulate the No. 1 tensioner to lock it and remove it, subsequently removing the chain tensioner slipper. Proceed to remove the idler sprocket shaft and the chain vibration dampers. Take note of the timing marks on each sprocket before removing the No. 1 timing chain and the crankshaft timing chain sprocket. On the right (rear) cylinder head, compress chain tensioner No. 2 and insert a drill bit or punch to lock it. Remove the camshaft timing sprockets and chain assembly, ensuring components are kept separate. Repeat the process for timing chain No. 3 on the left (front) cylinder head. Inspect all timing chain assembly parts for wear or damage, checking the chains for stretch and sprockets for appropriate diameter. Measure idler sprocket oil clearance and evaluate the condition of tensioners and vibration dampers. Ensure correct operation of the chain tensioners. During installation, lock chain tensioner No. 2 with a drill or punch, then proceed to install the tensioners, followed by the timing chains on the camshaft sprockets. Align yellow marking links and timing marks as specified. Install chain guides, the crankshaft timing sprocket, and the idler sprocket collar. Verify alignment of timing marks on camshaft sprockets. Install the No. 1 timing chain, ensuring proper alignment of marks, and lock the No. 1 tensioner with a drill or punch. Remove the drill or punch and confirm tension. Clean surfaces, install a new crankshaft oil seal, O-ring, and apply RTV sealant on the timing chain cover. Slide the cover into place, reinstalling all bolts sequentially and ensuring proper torque. Finally, follow the reverse procedure for the remaining installation steps, refilling fluids, reconnecting the battery, and checking for leaks upon starting the engine.

Question 5

How to remove the timing belt and Sprocket on Four cylinder engine on 1997 through 2001 Toyota Avalon?

Accepted Answer

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.

Question 6

How do you remove the timing belt and Sprocket on V6 engine on 2002 through 2006 Toyota Avalon?

Accepted Answer

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.
