Important:
• Do not reuse the exhaust manifold-to-cylinder head gaskets. Upon installation of the exhaust manifold, install a NEW gasket. • An incorrectly installed gasket or a leaking exhaust system may affect the performance of the On-Board Diagnostics (OBD) II system.
- Clean the exhaust manifold (1) with solvent.
- Dry the exhaust manifold (1) with compressed air.
- Inspect for a loose heat shield or for a damaged heat shield.
- Clean the exhaust manifold mating surface.
- Use a straight edge and a feeler gauge, and measure the exhaust manifold mounting face for warping.
- If the warping is greater than the maximum, repair or replace the exhaust manifold.
Important: For vehicles equipped with a PUP catalytic converter, do not splash any solvent down into the converter element.
Caution: Wear safety glasses in order to avoid eye damage.
