Q: How to Remove the Camshaft on 2008 Toyota Highlander?
A: The first step to replace the 2GR-FE camshaft involves removing the engine assembly after engine stand installation. Next, take out the ignition coil assembly, No. 2 engine mounting stay RH, intake manifold, exhaust manifold sub-assembly RH, No. 2 engine oil level dipstick guide, No. 2 manifold stay, No. 2 exhaust manifold heat insulator, exhaust manifold sub-assembly LH, transverse engine mounting bracket, generator assembly, V-ribbed belt tensioner assembly, No. 2 timing gear cover, No. 2 idler pulley sub-assembly, No. 1 engine front mounting bracket LH by removing the 6 bolts, radio setting condenser, No. 1 vacuum switching valve, knock control sensor wire, knock control sensor, crankshaft position sensor, No. 1 oil pipe, oil pipe, crankshaft pulley, oil cooler assembly (w/ Oil Cooler), No. 1 oil cooler bracket (w/ Oil Cooler), water inlet housing, water outlet, cylinder head cover sub-assembly (for Bank 1), cylinder head cover sub-assembly (for Bank 2), No. 2 oil pan sub-assembly, oil strainer sub-assembly, oil pan sub-assembly, timing chain cover sub-assembly, timing chain case oil seal, set No. 1 cylinder to TDC/compression, No. 1 chain tensioner assembly, chain tensioner slipper, chain sub-assembly, and idle sprocket assembly. First raise the No. 2 chain tensioner assembly and fix it with a 1.0 mm pin before using a wrench to remove the 2 bolts on each Bank 1 camshaft timing gear assembly so the cylinder head remains undamaged. Remove the No. 2 chain tensioner assembly by first evenly loosening the specified sequence of 8 and 12 bearing cap bolts then the 5 camshaft bearing cap. Remove the camshaft and No. 2 camshaft and then extract the camshaft housing sub-assembly RH with extreme caution. The inspection requires clamping the vise onto the assembly then setting the key groove and straight pin alignment while applying pressure that turns the assembly against the camshaft before torquing the bolt to 100 Nm (1,020 kgf-cm, 74 ft-lbf). Inspect smooth rotation and check locking at the most retarded position. The inspection process should be repeated for the camshaft timing exhaust gear assembly which needs to be properly aligned while its tightness is verified before the removal of the flange bolt and camshaft timing exhaust gear assembly.
