    Q:
    How can you check for warpage on the Exhaust Manifold if the gasket was leaking for the 2007 Toyota Highlander? Posted by Cesar F.
    A:
    Place a straight edge over the cylinder head mounting surface and try to insert a feeler gauge. If the clearance exceeds the limit, have the manifold resurfaced at an automotive machine shop. You can Select Your Vehicle to see complete installation and repair tips.

    Q:
    What is the procedure for removing the Catalytic Converter for the 2007 Toyota Sienna? Posted by Gayland B.
    A:
    Before removing the catalytic converter, spray the nuts on the exhaust flange studs with penetrating oil. Disconnect the flange at the rear of the converter; the front of the converter is welded to the pipe and must be cut for removal. Then, remove the nuts and separate the catalytic converter from the exhaust system. You can Select Your Vehicle to see complete installation and repair tips.
