  Q: How to remove the cylinder head gasket on 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.

  Q: How to install the cylinder head gasket on Toyota Matrix?

  A:

  A new gasket installation for the 2AZ-FE engine consists of setting the gasket on the block surface where the Lot No. stamp points upward followed by oil removal from contact areas while watching installation alignment. Install the cylinder head on the gasket before applying light engine oil to the threads and under heads of cylinder head set bolts. Use a 10 mm bi-hexagon wrench to evenly tighten 10 bolts and plate washers to 70 Nm (714 kgf-cm, 52 ft-lbf). Paint the front part of the bolts then increase additional torque to 90 degrees until the paint marks show a 90-degree relationship with the bolt fronts. After installing the No. 1 and No. 2 Camshaft bearings it is necessary to fit the camshafts before securing all hoses including inlet and outlet heater water and the No. 1 radiator hose. The ground cable of the engine wire must be torqued to 8.4 Nm (86 kgf-cm, 74 in-lbf) while all relevant sensors get connected. The No. 2 chain sub-assembly installation requires the crankshaft key placement then the alignment of yellow mark links at timing marks before tightening the oil pump drive shaft sprocket to 30 Nm (301 kgf-cm, 22 ft-lbf). Proper alignment of timing marks is necessary while installing the crankshaft timing gear or sprocket and the No. 1 chain vibration damper with a torque of 9.0 Nm (92 kgf-cm, 80 in-lbf) and the chain sub-assembly. After installing the chain tensioner slipper and timing chain guide the service technician must position the No. 1 Crankshaft Position Sensor plate. The installation of the timing chain or belt cover sub-assembly requires the additional step of the No. 1 chain tensioner assembly followed by the V-ribbed belt tensioner assembly which all need to be installed using the stated torque requirements. Place the crankshaft pulley under the restraint of Special Service Tool: 09213-54015 91651-60855 while applying 180 Nm (1835 kgf-cm, 133 ft-lbf) of torque. Subsequently install the oil pan sub-assembly with seal packing and tighten its bolts and nuts to 9.0 Nm (92 kgf-cm, 80 in-lbf). The crankshaft position sensor with specified torque values should be installed together with the idler pulley sub-assembly as well as the engine mounting insulator sub-assembly RH. The exhaust manifold converter sub-assembly needs a new gasket and its nuts must be tightened to 37 Nm (377 kgf-cm, 27 ft-lbf). Proceed with component installation that includes Intake Manifold followed by camshaft timing oil control valve assembly and fuel delivery pipe sub-assembly and engine oil level dipstick guide while maintaining proper torque standards. To complete the repair you should put on the V-ribbed belt before installing the front Exhaust Pipe assembly, the center exhaust pipe assembly and reconnecting the negative battery terminal at 5.4 Nm (55 kgf-cm, 48 in-lbf). Next, add engine oil and coolant then inspect the system for leaks.
