Introduction/Context This lesson will instruct students on the proper procedures needed to inspect, remove and replace engine mounts. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in an automotive repair facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to drivability concerns, safety problems, or customer satisfaction issues.

Content/Presentation/Demonstration Outline Instruct students that automotive engine assemblies are generally very heavy and require the use of lifting equipment (engine hoists, transmission and floor jacks, and sometimes either a 4 or 2 post lift). All safety precautions for this equipment should be followed and safety instruction on each should be completed prior to their use. Instruct students that engine mounts are normally made of steel and rubber molded together in such a way as to isolate engine vibration from the vehicle chassis, and driver. Deteriorated mounts can cause abnormal vibrations, sticking throttle and shift linkages, damaged hoses and wiring, and possible interference between radiator/shroud and fan (rear wheel drive), broken ground straps, and interference between engine, cylinder head, transmission, or exhaust system and body or frame. Instruct students that motor mounts may be specific side to side and improper installation may cause difficulty when reinstalling the engine or abnormal vibrations afterward. Some applications may benefit from installing the mounts and leaving the bolts loose until the engine is mounted in the chassis, then tightening the bolts (depending upon application). All bolts must be torqued to specifications and in the proper sequence. Additionally the Automotive Rebuilders Association reports that numerous cases of block distortion, resulting in scuffed pistons in cylinders near mounts that were improperly tightened. Instruct students to check for a broken mount by first installing scotch blocks under the vehicle wheels, then have another person put the transmission in both forward and reverse ranges while holding the brakes firmly. This will cause the engine to lift on one side, then the other. Slight throttle may need to be applied to cause the engine to rise up from the broken mount.

Applications/Practice 1 Refer to content.

Evaluation and feedback Prior to Testing or Lab Work Objective 1/ Formative assessment / Instructor will observe students as they practice the procedure to assure correct methods and safety practices are being followed. A checklist should be utilized to chart 1 student progress on the task. Questioning techniques will be utilized as necessary to demonstrate student comprehension / Adaptations and/or accommodations for special needs students will be added if required.

STUDENT ASSESSMENT: (Assess student progress with performance criteria.) 1 Objective 1/ Summative assessment / written test questions on stated objective / adaptation and / or accommodations for special needs students will be added if required.

IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)

REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)
