What is the cooldown limit after completing five dry motoring cycles?

• A. 15 minutes
• B. 5 minutes
• C. 30 minutes
• D. 1 hour

Answer: (A)

Cooldown after completing five dry motoring cycles is fifteen minutes. Dry motoring spins the engine without fuel to check the start system and lubrication path, but repeated cycles raise core and bearing temperatures. The 15-minute cooldown lets temperatures and oil pressures fall to safe levels before any further motoring or starts, protecting components from overheating and wear. The timer starts once the fifth dry motoring cycle finishes.
