Will a 2.2 ecotec from a 2005 Saturn Vue fit a 2002 grand am?

No, a 2.2 Ecotec engine from a 2005 Saturn Vue will not directly fit into a 2002 Pontiac Grand Am. Although both vehicles use the Ecotec engine family, there are differences in engine mounts, wiring harnesses, and other components that may prevent a straightforward swap. Additionally, the Grand Am may have different transmission compatibility and other system integrations that could complicate the installation.
