ENGINE WARM UP
Prior to takeoff, the engines must be run at low thrust to stabilize engine temps before takeoff thrust is selected.
After start, the engines must run at idle or taxi thrust for at least 4 minutes for cold engines or 2 minutes for warm engines.

More than 90 minutes
How long must the engines run at taxi or idle thrust before shutdown to cool down?
2 minutes
