• Q: How to remove the camshaft on 2009 Toyota Matrix?

  A: The first step of removing a 2AZ-FE engine camshaft requires the engineer to remove the engine under cover RH followed by the No. 1 engine cover sub-assembly. The essential step involves removing ignition coil assembly along with the spark plug. The removal process begins with detaching the two hoses for ventilation and then separating the two wire harness brackets before you can remove eight bolts, two nuts, and the two ventilation hose. Reach TDC/compression position of the No. 1 cylinder through crankshaft pulley rotation until the pulley groove connects with the timing mark "0" on the timing chain cover, while the camshaft timing gear and sprocket marks must match up with the No. 1 and No. 2 bearing caps; a single crankshaft pulley rotation is needed to achieve proper alignment. The technician marks the chain at the same position as the timing marks appear. First remove the No. 1 chain tensioner assembly after which you can loosen the No. 2 camshaft timing gear or sprocket by gripping the No. 2 camshaft with a wrench. The correct process to remove the No. 2 camshaft entails uniformly loosening and removing the 10 bearing cap bolts according to a specified sequence before extracting the 5 bearing caps while securely holding the No. 2 camshaft to detach the camshaft timing sprocket set bolt and sprocket with its timing chain. Start by uniformly removing the 10 bearing cap bolts and extracting all 5 bearing caps to retrieve the camshaft and camshaft timing gear assembly when holding the timing chain with a string for securement to the crankshaft sprocket. Ensure that no objects fall within the timing chain cover area. You must clamp the camshaft inside a vise during removal to stop movement while using vinyl tape to cover all oil paths besides the advance side path then using 150 kPa (1.5 kgf/cm2,22psi) of air pressure to operate the opened path by turning the camshaft timing gear assembly clockwise. Place a cloth across the paths before the operation to stop oil from splashing out. There are specific instructions for removing the flange bolt of the camshaft timing gear which mandates the preservation of all other 4 bolts while conducting camshaft timing gear reuse necessitates prior unlocking of straight pin lock mechanisms.
