Turbo Cooldown

[AlanD]

It is my understanding that after a spirited drive its advised that you let the turbo cool down by leaving the car to idle before you turn it off, is there any truth in needing to this on our KO3s turbos? And if so, for how long?

i was told to leave it for around 1min after a long or spirited drive

To be honest that's good practice with all engines, but more important on F.I cars.

The Mk5 does this for you, there is an auxillary pump which forces water backwards around the coolant system - it is a sort of failsafe and does it for c.3mins after you switch off the ignition.

yup the Borg Warner KKK K03s turbo is water cooled in the Mk5 GTI!!!!!

still doesn't mean u should rag it big time then just switch it off.

i tend to run no boost in the last mile of my journey and just cruise home!

Always best to leave it for a minute or so or end a spirited drive with an easy last few minutes, otherwise the turbo will begin to form cracks.

I always have a slow "run down" and then let her idle for 30 secs to a minute. Good preventative practice if you ask me.
