Introduction/Context / This lesson will instruct the student on how to diagnose and repair water leaks, dust leaks, and wind noise. 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 an automobile accident or create customer satisfaction issues.

Content/Presentation/Demonstration Outline

Instruct students that water leaks are noticed when moisture or rain enters the passenger compartment and collects on the carpeting. Air leaks nominally cause a whistling or hissing noise in the passenger compartment during driving. Tell them the principal methods used to locate air and water leaks are spraying water on the vehicle or applying a soap-and-water mixture that will bubble up when compressed air comes into contact with it, driving the vehicle over very dirty/dusty terrain, using a listening device, and directing a strong beam of light on the vehicle and checking for light leakage between panels
Tell students that before making any actual leak test, they should remove all applicable interior trim from the general area of the reported leak. Let them know that the spot where dust or water enters the vehicle might be some distance from the actual leak. Therefore, students should remove all trim, seats, or floor mats from the areas that are suspected as possible sources of the leak.
Inform students that entrance dust is usually noticed at the point of entrance. Tell them that these points should be sealed with an appropriate sealing compound and then rechecked to verify that the leak is sealed. Let students know that plugs and grommets are used in floor pans, dash panels, and trunk floors of a vehicle to keep dust and water from the interior. Tell students that these items should be carefully checked to ensure they are in good condition.
Instruct students that rattles and squeaks are sometimes caused by sheet metal that is too loose or rubbing adjacent parts. They are also caused by loose bolts and screws and improperly adjusted doors, hoods, or body panels. Tell students that other simple things, such as a broken or loose exhaust mount, an improperly secured jack or tire, or articles in the trunk, can also cause a rattle.
Tell students that oftentimes, a noise will be pinpointed by the customer to be in a certain area of the vehicle when in fact it might be caused by something in another area of the vehicle. This is caused by sound traveling through the body. Let students know that a thorough investigation and a test drive of the vehicle is recommended so that the rattle or noise can be located.
Inform students that most rattle noise repairs involve readjustment or replacement of parts, tightening loose attaching hardware, and welding broken parts. Many areas on the body of the vehicle can also cause rattles, noises, and squeaks. Let them know that the most susceptible areas are the dash, doors, steering column, and seat tracks. Tell them that all attaching hardware should be checked for tightness, especially in the area of the suspected noise source.


Applications/Practice

1 / Refer to content


Evaluation and feedback Prior to Testing or Lab Work

1 / Objective 1. / Formative assessment / Instructor will observe students as they practice the procedure to assure correct procedure and safety practices are being followed. A checklist will be utilized to chart 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.)
