Q: How to Remove the Camshaft on 2008 Toyota Highlander?
A: The first step for removing the 2GR-FE engine camshaft requires engine assembly removal along with 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, 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, and set No. 1 cylinder to TDC/compression. Extract the No. 1 chain tensioner assembly together with the chain tensioner slipper as well as the chain sub-assembly and idle sprocket assembly. Before removing the Bank 2 camshaft timing gears with No. 2 chain the technician should push down the No. 3 chain tensioner assembly and fix it with a 1.0 mm pin while using a wrench to hold the hexagonal camshaft portion then remove the 2 bolts and 2 camshaft timing gear assemblies without damaging the cylinder head. The camshaft bearing cap removal process starts with uniform and sequential bolt removal of the 8 and 13 bearing cap bolts followed by removal of the 5 bearing caps and latterly the No. 2 chain sub-assembly and No. 3 chain tensioner assembly. Use a screwdriver to pry off both the Number 3 and Number 4 camshafts with appropriate care for the contact surfaces. Insert the camshaft timing gear assembly into a vise while aligning the key groove with the straight pin. Press the assembly while turning it and tighten the flange bolt to 100 Nm (1,020 kgf-cm, 74 ft-lbf). Rotate the assembly smoothly while evaluating if it will operate in the most retarded position before unfastening the flange bolt and camshaft timing gear assembly. Perform the same steps for the camshaft timing exhaust gear assembly by first aligning all components correctly and then proceeding with proper pressing and tightening to match the specified torque before removing the flange bolt. Lastly, check for smooth rotation and locking at the most advanced position.
