ASE G1: Certification Test Preparation and Review
Coolant should be tested for - correct answer ✔✔a. Proper color
b. Freezing point (temperature)
c. Specific gravity
*d. Both b and c
Two technicians are discussing a compression test. Technician A says that the engine
should be cranked over with the pressure gauge installed for "4 puffs." Technician B says
that the maximum difference between the highest-reading cylinder and the lowest-reading
cylinder should be 20%. Which technician is correct? - correct answer ✔✔a. Technician A only
b. Technician B only
*c. Both Technicians A and B
d. Neither Technician A nor B
Technician A says that oil should be squirted into all of the cylinders before taking a
compression test. Technician B says that if the compression greatly increases when some oil
is squirted into the cylinders, it indicates defective or worn piston rings. Which technician is
correct? - correct answer ✔✔a. Technician A only
*b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
During a cylinder leakage (leak-down) test, air is noticed coming out of the oil fill opening.

specified
*b. Open bleeder valve(s) during filling
c. Use premixed coolant
d. Wear protective gloves
When replacing a water pump, be sure to - correct answer ✔✔a. Torque all fasteners to factory
specifications
b. Use a new gasket/ seal
c. Check that the accessory drive belt is properly aligned and adjusted to the proper
