Hello, my name is Mark Blocker, in this segment we're going to cover definition of preventative maintenance. OK, preventative maintenance is a term that briefly describes replacing a component when it's exceeded it's wear limits or exceeded it's life expectancy. Most all of the rubber components, belts, hoses, things of that nature have a certain life expectancy and if you replace those when they reach their life expectancy, you can prevent from replacing them after they've broken down. In most cases these items provide you with essential services like running the alternator, power steering, keeping the cooling in the cooling system. If you wait until they actually break or become defective and leak, then you're going to run into a problem where your car is broken down and your stuck on the side of the highway possibly blocking traffic or in a bad situation and usually requiring the use of a tow truck to get emergency assistance. If you replace these items when they reach their wear limits or expected life expectancy, you can prevent a breakdown thus that's how I came to the term of preventative maintenance. So preventative maintenance is maintenance done to prepare or to prevent breakdowns.
