To begin the removal process, first, disconnect the negative battery cable and proceed by removing the coolant overflow and windshield washer tanks, and if applicable, the front suspension upper brace on Solara models. Then, remove the drive belts from the alternator and power steering pump, followed by loosening the lug nuts on the right front wheel but leaving them in place. Raise the front of the vehicle, ensuring secure support on jack stands, and remove the right front wheel, inner fender apron, and the spark plugs. Position the number one cylinder at Top Dead Center (TDC) and support the engine from below, removing the engine movement control rod and its bracket, using a wooden block on the jack head for support. Additionally, remove the upper timing belt cover and gasket, ensuring the wiring harness is unclipped and pushed back. Verify installation marks on the timing belt or make new ones if obscured, and ensure proper alignment of the camshaft pulley timing marks. Remove the timing belt tensioner, release tension between the rear and front camshaft sprockets, and detach the timing belt from the camshaft sprockets. If needed, the camshaft sprockets can be removed after removing the valve cover. Next, remove the upper idler pulley, the crankshaft pulley bolt, and the crankshaft pulley itself, being cautious not to disturb the TDC position of the crankshaft. Remove the lower timing belt cover, the timing belt guide, and the timing belt itself, ensuring alignment marks are present or adding new ones. Remove the no. 1 idler pulley and plate washer using an Allen wrench, and if necessary, the crankshaft sprocket, taking care not to damage the crankshaft sensor portion. Inspect the belt tensioner for leaks and proper protrusion, and check the idler pulleys for smooth rotation. For installation, clean the timing belt area thoroughly, align the crankshaft timing sprocket keyway with the crankshaft key and install the sprocket, being cautious with the crankshaft sensor portion. Apply thread-locking compound to the lower idler pulley bolt and position the idler pulley and washer, tightening the bolt. Install the timing belt, starting with the crankshaft sprocket, ensuring alignment with marks on the belt, sprockets, and covers if reusing the original belt. Place the belt over the lower idler and water pump pulleys, slip the belt guide over the crankshaft, and install the lower timing belt cover and gasket. Fit the crankshaft pulley onto the crankshaft, aligning the keyway, and tighten the bolt while preventing the crankshaft from turning. Reinstall the upper idler pulley, ensuring smooth rotation. Place the front camshaft sprocket on the camshaft with the flange side out, aligning the pin hole with the camshaft pin, and install the retaining bolt while preventing camshaft movement. Double-check timing marks for alignment. If applicable, adjust the rear camshaft sprocket to align with the mark on the rear cover and place it on the camshaft with the flange side in, aligning the pin hole with the camshaft pin, and install the retaining bolt, again preventing camshaft movement. Slightly turn the front camshaft sprocket clockwise to add tension to the belt, then slip the belt onto the rear sprocket. Compress the timing belt tensioner pushrod, insert a pin, drill bit, or Allen wrench through the holes, and release the pressure. Install the timing belt tensioner, tighten the bolts, and remove the retaining pin. Rotate the crankshaft clockwise through two complete revolutions to recheck timing marks. Finally, reinstall the engine movement control rod's mounting bracket, upper timing belt cover and gasket, engine movement control rod and braces, and all other previously removed parts in reverse order.
