• Q: How to remove the cylinder head gasket on 2009 Toyota Corolla?

  A: The first step for cylinder head gasket removal from the 2ZR-FE starts by uninstalling the engine along with transaxle before installing the engine stand. Start by taking out the intake manifold before unhooking the fuel tube sub-assembly and removing the fuel delivery pipe sub-assembly followed by removal of the fuel injector assembly. The next step requires removal of all components starting from ignition coil assembly then moving to oil level dipstick sub-assembly, proceeding to No. 1 exhaust manifold heat insulator, and finishing with manifold stay, exhaust manifold, ventilation hose, No. 3 water by-pass hose, No. 1 water by-pass pipe, water by-pass hose, inlet water hose, inlet water, and lastly the thermostat. Detach both the radio setting condenser and the cylinder head cover sub-assembly from service. To set the No. 1 cylinder at TDC/compression alignment must occur between the crankshaft pulley groove and timing mark "0" on the timing chain cover while maintaining proper alignment of the camshaft timing gear and sprocket marks. Extract the crankshaft pulley while taking away the No. 1 chain tensioner assembly followed by the timing chain cover sub-assembly and timing chain cover oil seal and chain tensioner slipper. To release the No. 1 chain vibration damper workers must first remove two bolts and Clockwise turn the camshaft timing gear assembly by holding the hexagonal camshaft portion. The camshaft timing gear assembly requires a chain removal while the camshaft is turned clockwise until it reaches its original position. Next remove the No. 2 chain vibration damper from the camshaft assembly and proceed to inspect the camshaft timing gear assembly as well as the camshaft timing exhaust gear assembly before taking these components together with the camshaft bearing cap and camshaft out of the unit. Detach the No. 2 camshaft with additional items such as the No. 1 camshaft bearing and No. 1 valve rocker arm sub-assembly then remove the valve lash adjuster assembly and No. 2 camshaft bearing alongside the camshaft housing sub-assembly. Finished by applying a 10 mm bi-hexagon wrench to uniformly loosen then remove the 10 cylinder head bolts joined with 10 plate washers in the designated order. Afterward, carefully separate the cylinder head from the cylinder block using a pry tool. The last step removes the cylinder head gasket. The technician should conduct inspections on both No. 1 valve rocker arm sub-assembly and valve lash adjuster assembly and on the cylinder head set bolt when required.
