A well respected repair shop owner in the area reminded me of something to be aware of with the older model Subarus. He’s been seeing a lot of them coming in with blown head gaskets lately. It’s important especially with the colder weather coming to let these cars warm up before taking off for the day. Everything works better when it’s warmed up. If the gasket does blow, it’s best to find a shop that has experience replacing them-it will save you in the long run.
