What should a technician do if the upper radiator hose ruptures during an ASM test?

• A. Abort the test immediately and inform the customer about the coolant hose.
• B. Continue testing and report later.
• C. Replace the hose during the test.
• D. Ignore and resume testing.

Answer: (A)

Safety and proper procedure require stopping the test immediately when a coolant hose ruptures. A ruptured upper radiator hose can spray hot coolant, cause the engine to overheat, and create scalding or fire hazards. Aborting the test protects you and the vehicle, prevents coolant loss from skewing readings, and avoids further engine or equipment damage. After shutting down the engine and letting it cool, inform the customer what happened and what needs repair. Then replace the hose and inspect the cooling system before any subsequent testing.
