It is easier to see these problems when things are clean. I keep my engine bays clean for this reason, and because I’m picky.I use these washers for the same reason. It is easier to prevent and identify issues which will save you money. These are easy to install.When disconnecting your battery terminals, disconnect the negative terminal first, then the positive (red). When reconnecting connect the positive first, then the negative. Depending on the car and how long you had the battery disconnected, you may have to reset memories, radio settings, and drive to regain OBDII flags for emissions tests. If you have to have an emissions inspection, wait until after your inspection to disconnect the battery or it could be a hassle.These felt washers are a good choice.
