Regarding sectioning: ------CORRECT ANSWER---------------§ It should never be performed in a crush zone area, as this will change the crash characteristics of the vehicle. § When using recycled parts, the parts should first be checked for dimensional accuracy. Tolerance in terms of measurements can vary by as much as 5mm on undamaged models. Can it be acceptable to have a 5mm discrepancy on a control point of any vehicle? ------CORRECT ANSWER---------------Depends on the vehicle. Any point on a vehicle should vary from spec no more than ½ mm. An Improperly applied epoxy primer can lead to ------CORRECT ANSWER- --------------Sand scratch swelling, color bleeding, and peeling.

What should be used to determine vehicle centerline? ----- -CORRECT ANSWER---------------§ Centering gauges use centering pins to locate centerline. § A tram is used to make point-to-point measurements. Padded dashes can be repaired using: ------CORRECT ANSWER------------- --§ Airless plastic welder § Adhesives A wheel opening molding is located ------CORRECT ANSWER--------------- Along the opening in the quarter panel for the wheel 1.) A belt molding is located: ------CORRECT ANSWER---------------Along the belt line of the vehicle During sectioning, Tech A says that weld-through primer is enough corrosion protection for the inside of the welding joint. Tech B says that weld-through primer is not corrosion protection of the internal weld. Who is right? ------CORRECT ANSWER---------------Tech B. Weld-through primer is used in the weld joint only. The internal cavity will require corrosion protection. Technician A says to apply a two-part epoxy or self-etching primer over a repaired panel to fight corrosion. Technician B says the primer is not needed since weld-through primer was applied to the bare steel. Who is right? ------CORRECT ANSWER---------------Tech A. Two-part epoxy or self- etch primers are used as the base for corrosion protection. Weld-through primers are designed to be sandwiched between joining panels that are to be welded. In all other areas, the excess weld-through material should be removed. In a collision, battery acid is dropped on the turn signal socket. What is the proper procedure? ------CORRECT ANSWER---------------Replace the turn signal socket A technician sees that a damaged panel was replaced prior to the latest collision damage he is repairing. The seams appear to have corroded despite having been sealed with a heavy bodied seam sealer. The most likely cause of the corrosion is: ------CORRECT ANSWER---------------The 1st technician used a lacquer primer under the seam sealer. The adhesion of a lacquer primer is poor and only an epoxy or self-etching primer should be used. Severe rust and corrosion on the rocker panels could indicate: ------ CORRECT ANSWER---------------The use of frame straightening procedures may be unavailable. When performing an adhesive plastic repair, Technician A says an adhesion promoter is necessary if the base plastic is ground and it melts and smears. Technician B says the adhesion promoter is needed on plastics that do not melt and smear when ground. Who is right? ------ CORRECT ANSWER---------------Tech A. The sanding or grinding test is how the technician determines if the plastic is a polyolefin, which requires an adhesion promotor. However, an adhesion promoter can be used on all plastics. Technician A says the best way to remove an encapsulated quarter glass is to use a hot knife to soften the urethane bed. Technician B says an induction heater can be used to do the same task. Who is right? ------ CORRECT ANSWER---------------Both A & B. While the hot knife is an old method, both methods will work. A bent rim can be result of: ------CORRECT ANSWER---------------§ Curbing § Hitting a pothole § Impact in a motor vehicle accident Technician A says that a slight over-pull may be necessary to get a structural panel back to specification. Technician B says over-pulling can require panel replacement. Who is right? ------CORRECT ANSWER---------- -----Both technicians are correct. Because some metals have a spring back condition after being compressed in a collision, sometimes over-pulling is necessary. Care must be used not to over-pull beyond the spring back because it is almost impossible to repair an over-pull condition without replacement of the panel. OEM ------CORRECT ANSWER---------------Original Equipment Manufacturer 1.) Clear coat is used primarily for its: ------CORRECT ANSWER--------------- UV Protection When using centering gauges to measure height, Technician A says to measure from the base of the gauge to the frame rack. Technician B says to gauge height by comparing the outer gauges to the base reference gauges. Who is right? ------CORRECT ANSWER---------------Technician B. Gauges should be compared to the base gauges that have been preset to the correct height. The modern vehicle combines the quarter panel and the roof pillar structure into one part, which eliminates: ------CORRECT ANSWER--------------- Vehicle weight and additional parts The door striker bolt can be adjusted to set: ------CORRECT ANSWER------ ---------The depth of the door to either the rear door or the quarter panel. R & I ------CORRECT ANSWER---------------Remove and Install for seven hours to repair the rail. However, after the seven hours of labor have elapsed, the rail still shows hammer marks and signs of having been bent. Technician A says a thin coat of body filler will cover the damage and should be acceptable. Technician B says spreading body filler over damaged structural parts would only be concealing the damage. Who is right? ------CORRECT ANSWER---------------Technician B. A structural component such as a frame rail that cannot be restored to its original dimensions and appearance using metal straightening methods should be replaced. To attempt to conceal structural damage using a body filler is not only risking the safety of the repair and the lives of the vehicle's occupants, it is an act for which civil liabilities exist. When replacing a full frame, Technician A says that the old frame must still be measured and rough-pulled prior to removal. Technician B says that the replacement frame should be dimensioned also. Who is right? ------ CORRECT ANSWER---------------Both technicians are right. Before replacing a full frame, the old frame must be roughed back into position in order to bring the connected body back into position. It is recommended that the dimensions of the replacement frame be checked also, as the frame could have been damaged in shipping. Which of these is LEAST likely to cause wheel burn when buffing or polishing a topcoat? ------CORRECT ANSWER---------------§ use of an abrasive compound § insufficiently cured paint § cold shop conditions § using a high-speed polisher According to the Federal Motor Vehicle Safety Standard, a vehicle with front end damage requires the repair to include: ------CORRECT ANSWER- --------------Bumpers that can absorb an impact speed of at least 2.5 mph. Acid rain damage can appear as: ------CORRECT ANSWER--------------- water spots The identifying marks on a plastic part are so worn down they cannot be read. Therefore, the plastic cannot be identified. Technician A says you can determine the type of plastic by cleaning an area of the damaged part and seeing if one of the plastic welding rods will stick to it. Technician B says you can determine the type of plastic by making small circular wafers from the repair materials and comparing their flexibility to the flexibility of the part being repaired. Who is right? ------CORRECT ANSWER---------------Both technicians are correct Which of the following is used to form a seal and keep window glass in place in replacing the glass in a vehicle? ------CORRECT ANSWER---------- -----Filler strip seals the glass in place. The filler strip is inserted into the gasket. A car has adjustable door hinges. There is a significant gap at the top of the front top and the bottom as well between the front fender and the windshield support column of the door. Technician A says the gap can be adjusted by repositioning the hinges. Technician B says the gap can be adjusted by shimming the hinges. Who is right? ------CORRECT ANSWER- --------------Technician A is correct. Shimming the hinges would not lessen the door gap. Adjusting the hinges should solve this problem. The auto appraiser considers the extent of damage, the size of the damaged area, and the appearance. Usually, if the repair cost exceeds ____ of the cost to replace the part, replacement is appropriate. ------ CORRECT ANSWER---------------75% A late model vehicle sustains a serious front-end collision that results in both its energy absorbers being compressed. Technician A wants to immediately remove and replace the energy absorbers. Technician B says that instead, holes should be immediately drilled in the absorbers so they can be better evaluated before checking the manufacturer's recommendations. Who is right? ------CORRECT ANSWER--------------- Neither technician is right. The manufacturer's recommendations should always be checked before anything is done because the engineering of the absorbers differs from one manufacturer to another. When mounting a full frame vehicle to the alignment rack, Technician A says a T-hook slot should be used to hold the vehicle to the rack. Technician B says the T-hook slots were designed for transportation and will not withstand pulling and anchoring without damage. Who is right? ------ CORRECT ANSWER---------------Technician B is right. T-hook slots should only be used when transporting a vehicle. They are not designed to hold or withstand pulling forces. A windshield is being replaced in a vehicle using the partial cutout method. Technician A says to remove all of the old urethane except the pinchweld primer. Technician B says the original urethane should remain in place and be used as a base for the new urethane installation. Who is correct? ------ CORRECT ANSWER---------------Technician B is correct. When the partial cutout method is used, the original urethane remains in place as a base for the new urethane installation. Rail dust damage appears as: ------CORRECT ANSWER---------------Small points of rust in the finish. The first step a painter takes in preparing a car for paint is: ------CORRECT ANSWER---------------Water and detergent wash 4th Stroke ------CORRECT ANSWER---------------Exhaust stroke- as piston travels upwards, exhaust valve opens to release burned fuel air mixture. When piston reaches the top of the stroke, the intake valve opens and the cycle begins all over again. anti-freeze/coolant ------CORRECT ANSWER---------------Need to keep engine from overheating or freezing liquid that prevents engine from overheating and freezing When mixed with water, lowers freezing point and raises boiling point Includes corrosion inhibitors to prevent rust on water pumps or engine blocks If antifreeze is brown on rusty, inhibitors have broken down - will need to be replaced Specific colors of antifreeze mean certain things What does the exhaust do? ------CORRECT ANSWER---------------Brings waste gasses away from the engine out through tail pipe (rear of vehicle) Waste gas is corrosive Modify the noise of the exhaust, reduces emissions, and enhances the performance of the engine Exhaust consists of ------CORRECT ANSWER---------------Heat Shield Exhaust Manifold/Header ------CORRECT ANSWER---------------gathers the gasses from each cylinder- one pipe per header Joins to one pipe and makes its way to the vehicle EGR valve controls gasses- takes gases and mixes in intake system, mixes with intake gases to reduce combustion temp; cuts down on nitrogen oxide in the emissions Catalytic Converter* ------CORRECT ANSWER---------------middle of the car underneath; most expensive part of exhaust system Takes the pollutants in exhaust system and converts them into less harmful gasses Only works at high temp 750 F As close to the manifold as possible Rear Oxygen Sensor ------CORRECT ANSWER---------------measures amount of oxygen in the exhaust and compares to first sensor amount of oxygen should have changed Makes sure the catalytic converter is working Legal requirement on all vehicles for emissions: First Muffler/Silencer- First Muffler/Silencer ------CORRECT ANSWER---------------reduce the amount of noise coming off of the vehicle Oxygen Sensor ------CORRECT ANSWER---------------at least one or two or more; front oxygen sensor detects amount of oxygen in the exhaust system; determines how much fuel is injected into the engine GR Pipe ------CORRECT ANSWER---------------runs off the header, back of the engine, back to air intake and back to intake manifold Rear muffler ------CORRECT ANSWER---------------much bigger, more of an absorption Tail pipe ------CORRECT ANSWER---------------takes the exhaust gases and vents out of vehicle All exhaust systems ------CORRECT ANSWER---------------are sectional designs; bolted together by exhaust flanges In-between joints are gaskets Most common type of steering ------CORRECT ANSWER---------------rack and pinion Rack ------CORRECT ANSWER---------------center of mechanism- constrained and can only move in straight line Pinion ------CORRECT ANSWER---------------Makes the rack move Steering arm ------CORRECT ANSWER---------------attached to both wheels only has rotational movement connected to the car frame via roller bearing for turning Tie rod connects the ------CORRECT ANSWER---------------steering arm to the rack; can have transitional and rotational movement When rack moves ------CORRECT ANSWER---------------Wheels turn at different angles; meeting point always lies on the rear wheel line
