  • Remove the old gasket by scraping it off of the intake manifold with a razor blade. Do not get any of the old gasket into the hole that the thermostat was removed from.

  • Place a bead of RTV silicone gasket maker onto the gasket surface of the intake manifold and allow to to dry for 10 minutes before moving on.
