Automotive Engine Repair Fundamentals (II) Hours 45

In this course the student will learn general engine vacuum tests and to perform general cylinder tests and determine necessary action. Students will cover gaskets and seals on pans and covers, an how to prime the lubrication system. Students will also learn to perform oil pressure tests, as well as to test and replace thermostats, water pumps, radiators and fan clutches. Students will also learn to inspect test and replace oil and water sending units and switches.
