How to replace the camshaft on 2005 Toyota Highlander?

Question

Accepted Answer

The replacement of the camshaft starts with removal of several components including front wheel RH, front fender splash shield front RH, front fender apron seal RH, engine cover sub-assembly No.1, ignition coil assembly, spark plug, ventilation hoses, engine wire, and cylinder head cover sub-assembly. Proceed with the removal of chain tensioner assembly No.1 while the first cylinder is set to TDC/compression. Attach a wrench to the No. 2 exhaust camshaft before unscrewing its sprocket bolt yet maintain the valve lifter from harm. Unfasten bearing cap bolts through the specified order before raising the camshaft with its sprocket bolt to disconnect the camshaft timing sprocket from the timing chain during service. The intake camshaft removal process requires bearing cap bolt loosening in order along with subsequent removal of the camshaft followed by string-based timing chain securing to prevent items from falling into the timing chain cover. The process for removing the camshaft timing gear assembly includes fixing the intake camshaft in a vise while taping all paths except the advanced side and applying air pressure of 150 kPa (1.5 kgf/cm2, 21 psi) to the advanced angle port and containing any oil spray residue with a shop rag. You should be able to turn the camshaft timing gear to advanced angle position by hand before removing the fringe bolt which must not touch other four bolts. To assemble the camshaft timing gear assembly properly fit it to the straight pin and key groove then spin it while using pressure on the camshaft until the fringe part of the gear aligns with the camshaft. The technician should secure the fringe bolt at a torque of 54 Nm using engine oil on both threads and beneath the bolt head. The camshaft timing gear receives the timing chain once its painted feature matches the camshaft timing sprocket timing marks before bearing cap installation accomplished by torquing bolts according to specs. Synchronize the No. 2 camshaft (exhaust) to the camshaft timing sprocket timing mark before securing the sprocket bolt with moderate force then add bearing caps and bolts that require precise torque values. Complete the procedure by checking paint mark alignment, installing chain tensioner assembly No.1 followed by the cylinder head cover sub-assembly then connecting the engine wire followed by installing the ignition coil assembly with 9.0 Nm torque (92 kgf-cm, 80 inch lbs.) and spark plugs held with a torque of 19 Nm (194 kgf-cm, 14 ft. lbs.) along with the front wheel RH installation and inspection for oil leaks.
