Can a jumped timing chain cause an oil or coolant leak?
The timing chain does not have anything to do with the cooling system and would not have caused a coolant leak. Your car has a warning indicator that lights up in the dash when it is low on coolant or oil telling the driver to shut the engine off, but it will NOT shut off on it’s own.

When to turn on the cooling fan relay?
The cooling fan relay is an electromagnetic switch that controls the power supply to the engine’s cooling fans.
