  Q: How to remove and reinstall exhaust manifolds on V6 engine for 1997 through 2001 Toyota Solara and 1997 through 2001 Toyota Avalon?

  A: Disconnect the negative cable from the battery. Spray penetrating oil on the exhaust manifold fasteners and allow it to soak in. Remove the heated oxygen sensors from the front and rear manifolds. Remove the EGR pipe from the rear exhaust manifold and Cylinder Head. Remove the nuts retaining the exhaust pipes to the front and rear exhaust manifolds. Disconnect the electrical connector from the oxygen sensor at each manifold. Unbolt the exhaust manifolds from the cylinder heads and slip them off the mounting studs. Carefully inspect the manifolds and fasteners for cracks and damage. Use a scraper to remove all traces of old gasket material and carbon deposits from the manifolds and cylinder head mating surfaces. If the gasket was leaking, check the manifolds for warpage on the cylinder head mounting surface by placing a straightedge over the surface and trying to insert a feeler gauge. If the clearance exceeds the limit, have the manifold resurfaced at an automotive machine shop. Position new gaskets over the cylinder head studs. Install the manifolds and thread the mounting nuts into place. Working from the center out, tighten the nuts. Reinstall the remaining parts in the reverse order of removal. Use new gaskets when connecting the exhaust pipes. Run the engine and check for exhaust leaks.

  Q: How to remove and install an exhaust manifold on V4 engine for 1997 through 2001 Toyota Solara and 1997 through 2001 Toyota Avalon?

  A: Disconnect the negative cable from the battery. Unplug the oxygen sensor wire harness and the clamp over the harness. If you're installing a new exhaust manifold, remove the sensor. Remove the upper heat insulator from the manifold by removing the exhaust manifold heat insulator bolts. Apply penetrating oil to the exhaust manifold mounting nuts/bolts. Disconnect the exhaust pipe from the exhaust manifold. Remove the exhaust manifold brace (some models have two braces) and lower heat insulator by unbolting the exhaust manifold flange brace near the front engine mount. Remove the nuts/bolts and detach the manifold and gasket by removing the exhaust manifold fasteners at the cylinder head. Use a scraper to remove all traces of old gasket material and carbon deposits from the manifold and cylinder head mating surfaces. If the gasket was leaking, have the manifold checked for warpage at an automotive machine shop and resurfaced if necessary. Position a new gasket over the cylinder head studs. The marks on the gasket should face out (away from the head) and the arrow should point toward the rear (transaxle end) of the engine. Install the manifold and thread the mounting nuts/bolts into place. Working from the center out, tighten the nuts/bolts. Reinstall the remaining parts in the reverse order of removal. Run the engine and check for exhaust leaks.

  Q: How to remove and reinstall exhaust manifolds on V6 engine for 2002 through 2008 Toyota Solara and 2002 through 2006 Toyota Avalon?

  A: Disconnect the negative cable from the battery. Spray penetrating oil on the exhaust manifold fasteners and allow it to soak in. Remove the heated oxygen sensors from the front and rear manifolds. Remove the EGR pipe from the rear exhaust manifold and Cylinder Head. Remove the nuts retaining the exhaust pipes to the front and rear exhaust manifolds. On the front manifold, remove the two bolts securing the manifold support bracket. Disconnect the electrical connector from the oxygen sensor at each manifold. Remove the bolts and the heat shield over the exhaust manifolds. Unbolt the exhaust manifolds from the cylinder heads, working from the ends toward the middle, and slip them off the mounting studs. Carefully inspect the manifolds and fasteners for cracks and damage. Use a scraper to remove all traces of old gasket material and carbon deposits from the manifolds and cylinder head mating surfaces. If the gasket was leaking, check the manifolds for warpage on the cylinder head mounting surface by placing a straightedge over the surface and trying to insert a feeler gauge. If the clearance exceeds the limit, have the manifold resurfaced at an automotive machine shop. Position new gaskets over the cylinder head studs. Install the manifolds and thread the mounting nuts into place. Working from the center out, tighten the nuts. Reinstall the remaining parts in the reverse order of removal. Use new gaskets when connecting the exhaust pipes. Run the engine and check for exhaust leaks.

  Q: How to remove and install an exhaust manifold on V4 engine for 2002 through 2008 Toyota Solara and 2002 through 2006 Toyota Avalon?

  A: Disconnect the negative battery cable and raise the vehicle on jackstands. Remove the lower splash shields and apply penetrating oil to the exhaust pipe bolts. Remove these bolts and separate the exhaust pipe from the manifold, taking care not to damage the oxygen sensor. Remove the lower exhaust manifold braces and oxygen sensor connectors. In the engine compartment, remove the upper heat shield and detach the manifold and gasket. Scrape off old gasket material from the manifold and cylinder head. If the gasket leaks, replace the warped manifold. Position a new gasket over the cylinder head studs, noting any directional marks. Install the manifold and tighten the nuts/bolts from the center out. Reinstall the remaining parts in reverse order and check for exhaust leaks after running the engine.
