Over the last few months my family has acquired 4 Aveos (2004-2006) and I get to keep them all running. I have discovered that seemingly all Aveos need the plastic thermostat housing replaced with a metal one, a valve cover seal replacement, plugs, wires, and the automatics need shift lock solenoids. Now that I've done all that, what else should I watch out/plan for? Any other super common issues? Or stuff I should just deal with now instead of on the side of the highway later?
