Counterman B says a wobbly shaft or leaks from the vent hole are indications of a water pump that needs to be replaced. Who is right? - correct answer Both Counterman A and B "Dex-Cool" antifreeze is what color? - correct answer Orange Counterman A says mixing ordinary antifreeze with Dex-Cool does not affect the service life of the coolant. Counterman B says the reserve alkalinity of a coolant is a measure of its resistance to freezing. Who is right? - correct answer Neither one A serpentine belt should be replaced: - correct answer If the V-grooves on the underside are worn; If it is contaminated with grease or oil; If it has visible cracks or damage Counterman A says most "long life" coolants usually have a service life of five to seven years or 100,000 to 150,000 miles. Counterman B says failure to change the coolant regularly can cause corrosion inside the radiator, heater core and engine. Who is right? - correct answer Both Counterman A and B Counterman A says constant velocity joints are used on front-wheel drive cars and some rear-wheel drive cars. Counterman B says a worn outer CV joint often makes a clicking noise when turning. Who is right? - correct answer Both Counterman A and B What type of CV joints "plunge" and allow the halfshaft to move in and out as the height of the suspension changes? - correct answer Crossgroove CV joints & Double-Offset CV joints The rubber or plastic boot around a CV joint does what? - correct answer Keeps out moisture; Keeps out dirt; Prevents the loss of grease Counterman A says U-joints can cause driveline clunks and vibrations if the joint is worn. Counterman B says a CV joint will soon fail if a leaky, torn, or missing boot is not replaced. Who is right? - correct answer Both Counterman A and B Constant velocity joints require what type of grease? - correct answer CV joint grease "Rzeppa" CV joints can NOT: - correct answer Operate at angles of up to 90 degrees "Rzeppa" CV joints: - correct answer Contain six steel balls; Are most often used for the outer joint on FWD cars; Are sealed inside a protective rubber or plastic boot "Tripod" CV joints are NOT: - correct answer Used only for inner joints on FWD cars "Tripod" CV joints: - correct answer Allow the halfshaft to plunge in and out; Contain three roller bearings on a tripod; Are used on many domestic and import vehicles Counterman A says a replacement halfshaft must be the same length as the original. Counterman B says some vehicles like Honda may use any one of several different halfshaft assemblies. Who is right? - correct answer Both Counterman A and B Counterman A says a worn wheel bearing make chirping or growling noises while driving. Counterman B says wheel bearing grease seals can always be reused when servicing the wheel bearings or front disc brakes. Who is right? - correct answer Counterman A only Sealed wheel bearings: - correct answer Cannot be lubricated; Must be replaced as an assembly; Are not adjustable Which components are a part of the emission control system? - correct answer EGR valve; Oxygen sensor; Powertrain control module (PCM) Counterman A says oxygen sensors monitor the engine's air/fuel mixture. Counterman B says three-wire oxygen sensors have a heater element inside for faster warm-up. Who's right? - correct answer Both Counterman A and B Counterman A says a "Check Engine" light usually indicates a fault that affects emissions. Counterman B says a car can usually pass an OBD II plug-in emissions test by clearing any trouble codes just before the test. Who is right? - correct answer Counterman A only A "sluggish" oxygen sensor: - correct answer Responds too slowly for good engine performance; Probably has a lot of miles on it; May be contaminated Crankcase combustion vapors and moisture are eliminated by which of the following emission control devices? - correct answer PCV valve Counterman A says a plugged EGR valve will cause carbon monoxide (CO) emissions to increase.
