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

  A: A proper procedure to remove the cylinder head gasket of the 2AZ-FE engine begins with fuel system pressure discharge followed by battery cable disconnect from the negative terminal then removal of the front wiper arm head cap together with the left and right front wiper arm and blade assemblies. The hood to cowl top seal should be removed together with the right and left cowl top ventilator louvers and the windshield wiper motor and link assembly. The worker should detach the outer cowl top panel followed by the suspension tower damper assembly (only if the front strut bar is present) before removing the right front wheel. The engineer needs to remove engine under covers from both sides and drain motor oil and engine coolant from the No. 1 engine cover sub-assembly. The repair technician should detach the center exhaust pipe assembly for both 2WD and 4WD vehicles together with the front exhaust pipe assembly, V-ribbed belt and generator assembly. The radiator reserve tank assembly can be separated before removing the air cleaner cap sub-assembly with hose and the throttle body assembly and ignition coil assembly and spark plug. Proceed by removing the cylinder head cover sub-assembly before disconnecting the fuel main tube and then taking off the fuel delivery pipe sub-assembly. The technician must take away the camshaft timing oil control valve assembly together with the intake manifold and the No. 1 intake manifold insulator as well as the manifold stays and the No. 1 exhaust manifold heat insulator. Disconnection of the air-fuel ratio sensor connector followed by 5 nut removal allows separation of the exhaust manifold converter sub-assembly. The right side engine mounting insulator sub-assembly can be removed under support of an engine floor jack. The replacement process starts with removing the idler pulley sub-assembly followed by the oil pan sub-assembly using new bolts to install the No. 1 and No. 2 engine hangers under sling device control while careful sealing sealer cutting procedures must be observed. Set the No. 1 cylinder to TDC/compression by appropriate timing of the crankshaft pulley timing mark with the timing chain cover while also checking the camshaft timing gear and sprocket alignment. First remove the crankshaft pulley then proceed to eliminate the No. 1 chain tensioner assembly, V-ribbed belt tensioner assembly, crankshaft position sensor and timing chain or belt cover sub-assembly from the system. Extraction of the No. 1 crankshaft position sensor plate along with timing chain guide and chain tensioner slipper and No. 1 chain vibration damper must occur. The crankshaft timing gear or sprocket and chain sub-assembly need to be detached together after which you should remove the No. 2 chain sub-assembly by aligning the adjusting hole through crankshaft rotation followed by gear locking. The service procedure starts with disconnecting No. 1 radiator hose and margin and inlet heater water hoses followed by the engine wire separation by disconnecting multiple connectors while untying the ground cable. It is time to remove the cylinder head sub-assembly together with the No. 2 camshaft, camshaft, No. 1 and No. 2 camshaft bearings using a uniform tightening pattern of 10 cylinder head bolts and plate washers while following a specific sequence. Afterward, carefully remove the cylinder head from the contact surfaces and take off the cylinder head gasket.
