Turbo squelching.

[Typhoon]

O.K, odd title. When I shut the car down (yes a few minutes idling, and mild throttle before parking) the top turbo coolant line will make a squelch sound for a few seconds, a couple of times.
Is this just the hot section of the turbo overheating the coolant locally after shutdown, turning it into vapour? Anyone else's do this? Both the turbo coolant lines are in good condition, with new rubber sections. Rest of the cooling system A1, good pressure, no overheating etc.
Should I worry, or is it just a turbo thing?

Regards, Andrew.

there is a small leak in the line, touch it with a screwdriver and it will either blow out harder or it will stop.

I hope there is clamps on these lines otherwise they will leak, if there is clamps tighten them down.

but if you really want to find the trouble area touch each line with a screw driver like i said
