Coolant flows through the engine anytime it is running, it might not be passing through the radiator at idle, but through the bypass hoses and heater cores. It's my understanding that idling the motor after long runs prevents hot spots from developing in the coolant passages in the heads and boiling the coolant at that point.

It was my understanding that the engine be allowed to idle for a minute before shutting off after a long trip for cooling reasons. If no coolant is flowing at idle then there is no reason to do this. Is this necessary? Darren |
