WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
  • To avoid the danger of being scalded, never drain the coolant when the engine is hot.
  • The gasket for intake manifold collector (upper) is secured together with intake manifold collector (lower) bolt. Thus, when replacing only the upper gasket the lower gasket must also be replaced.
  1. Remove the cowl top. Refer to COWL TOP .
  2. Remove the windshield wiper assembly. Refer to REMOVAL AND INSTALLATION FOR WIPER MOTOR .
