the timing cover gasket is leaking (I think coolant) on my 2005 chevy equinox. on 2005 Chevrolet Equinox

I keep having to add coolant. I'm told I need a $12 piece but the job will cost $490. Can this be right? How can I get it done cheaper?

The way to do it cheaper is to buy the $12 part(s), and do the work yourself. Gaskets are not expensive, but labor is not cheap. Sorry not to have a better answer, but the truth hurts.
