  Q: How to remove and install an intake manifold on V6 engine on 2002 through 2006 Toyota Avalon?

  A: To remove the upper intake plenum, release the fuel system pressure, and detach the battery cable. Drain the coolant and remove the V-bank cover and air cleaner. Disconnect connectors and hoses from the throttle body, and the throttle motor connector. Remove the suspension brace and intake plenum braces. Remove bolts and nuts holding the plenum to the lower intake manifold. For the lower manifold, disconnect connectors as well as the hoses.

  Q: How to remove and install an intake manifold on Four cylinder engine on 1997 through 2001 Toyota Avalon?

  A: Disconnect the negative cable from the battery. Loosen the air cleaner hose clamp at the throttle body and remove the air cleaner top (four clamps), resonator, and hose. Disconnect the coolant hoses from the throttle body and plug them to prevent coolant leakage. Label and detach any wire harness and control cables or hoses connected to the intake manifold. Press in on the clips to release the wiring harness retainers. Disconnect the two ground straps from the firewall side of the intake manifold, then disconnect the knock sensor. Carefully lift the wire harness over the manifold. Unbolt the intake manifold-to-engine braces. Disconnect the electrical connectors from the coil pack, then remove the mounting bolts and remove the coil pack mount/intake brace. Remove the mounting nuts/bolts, then detach the manifold from the engine. Use a scraper to remove all traces of old gasket material and sealant from the manifold and Cylinder Head, then clean the mating surfaces with lacquer thinner or acetone. If the gasket was leaking, have the manifold checked for warpage at an automotive machine shop and resurfaced if necessary. Install a new gasket, then position the manifold on the head and install the nuts/bolts. Tighten the nuts/bolts. Work from the center out towards the ends to avoid warping the manifold. Install the remaining parts in the reverse order of removal. Before starting the engine, check the throttle linkage for smooth operation. Check the coolant and add some if necessary to bring it to the appropriate level. Run the engine and check for coolant and vacuum leaks. Road test the vehicle and check for proper operation of all accessories, including the cruise control system.

  Q: How to remove and install an intake manifold on Four cylinder engine on 2002 through 2006 Toyota Avalon?

  A: Removal begins with relieving the fuel system pressure, then disconnecting the negative cable from the battery. The air intake duct and resonator are removed, followed by the cowl cover and vent tray. On models with performance suspension, the brace between the shock towers is removed. The fuel rail and injectors are removed as an assembly. The electronic throttle motor connector is disconnected and the throttle body is removed. The PCV and vacuum hoses connected to the rear of the intake manifold are labeled and detached. The vehicle is raised and supported securely on jackstands. Working below the vehicle, the manifold lower mounting bolts are removed. From above, the intake manifold upper mounting nuts and bolts are removed. The manifold, the gasket, and the manifold insulator are removed from the engine. For installation, the mating surfaces of the intake manifold and the Cylinder Head mounting surface are cleaned with lacquer thinner or acetone. If the gasket shows signs of leaking, the manifold is checked for warpage with a straight edge. If the manifold is warped, it must be replaced. A new gasket is pressed into the grooves on the intake manifold. The manifold and gasket are installed over the studs on the cylinder head. The manifold-to-cylinder head nuts/bolts are tightened in three or four equal steps. Work from the top bolts down to avoid warping the manifold. The remaining parts are installed in the reverse order of removal. The coolant level is checked, adding as necessary. Before starting the engine, the throttle linkage is checked for smooth operation. The engine is run and checked for coolant and vacuum leaks. The vehicle is road tested and checked for proper operation of all accessories, including the cruise control system, if equipped.

  Q: How to remove and install an intake manifold on V6 engine on 1997 through 2001 Toyota Avalon?

  A: Start by relieving fuel system pressure and disconnecting the battery cable. Drain coolant and remove the V-bank cover, air cleaner assembly, and disconnect connectors and hoses from the throttle body. Remove the throttle body if needed. On Solara models, remove the front suspension brace. Disconnect the EGR pipe and unbolt the intake plenum braces. Remove the bolts and nuts holding the plenum to the lower intake manifold and lift off the plenum. To remove the lower intake manifold, disconnect connectors from the fuel injectors and disconnect the air assist and heater hoses. Detach the fuel line and remove the eight mounting nuts/bolts. Replace the water transfer hose if the intake manifold is removed. To install, clean the mating surfaces and install new gaskets. Tighten the nuts/bolts. Reinstall the remaining parts in reverse order and refill the cooling system. Check for leaks.

  Q: How to remove and install an intake manifold on V6 engine on 2007 through 2015 Toyota Avalon?

  A: Disconnect the battery's negative terminal cable, all hoses, and wiring from the throttle body. Label hoses for reassembly. Remove the throttle body bracket, upper intake manifold brace, and air intake tube. Disconnect all wiring and hoses from the manifold, remove the upper intake manifold. Check the gasket's condition, replace if needed. For lower intake manifold removal, remove the fuel rail and interfering brace. Discard old lower intake manifold gaskets, clean off old gasket material from the manifold and cylinder heads. Installation is the reverse of removal, use new gaskets and tighten bolts in a criss-cross pattern from the center outward.

  Q: How do you remove the intake manifold on Four cylinder engine on 2007 through 2015 Toyota Avalon?

  A: To remove the intake manifold, start by relieving the fuel system pressure and disconnecting the negative battery terminal. Remove the air intake duct, radiator, and cowl cover assembly. For 2009 and earlier models, remove the fuel rail and injectors, throttle linkage, and throttle body from the intake manifold. Label and detach the PCV and vacuum hoses connected to the rear of the intake manifold. Raise the vehicle and remove the manifold lower mounting bolts. From above, remove the intake manifold upper mounting nuts and bolts, along with the manifold, gasket, and manifold insulator. For 2010 and later models, remove the engine cover, disconnect vacuum hoses and ventilation tubes, and remove the throttle body from the intake manifold. Disconnect the fuel intake line from the fuel rail and disconnect the electrical connectors and harness mounting fasteners. Disconnect and remove the main harness connector from the intake manifold and tumble control valves. Apply battery voltage to the tumble control valve electrical connector to close the valve. Remove the intake manifold support bracket and disconnect the vacuum switching valve assembly electrical connector. Unscrew the intake manifold mounting fasteners and remove the manifold. To install, clean the mating surfaces and check for warpage. Press a new gasket into the grooves on the intake manifold and install it over the studs on the Cylinder Head. Tighten the manifold-to-cylinder head nuts or bolts in three or four equal steps. Install the remaining parts in reverse order and check for coolant and vacuum leaks.
