How do I determine if I have a Phase I or Phase II 2.5 L engine? And
what distinguishes an early Phase II from later Phase II?

I'm thinking about buying a Chevy Equinox with the old venerable small
block engine. Subaru seems to have an engine design problem.

Thanks mrputer for your response. A minute after I submitted my
request it dawned on me to use Google. I had a senior moment.

Have a good day.
