Leave engine running after drive?

[Jackie Treehorn]

Hi

Quick Question

Years ago it seemed all the craze, with R5 GT Turbos Uno etc.

Then it seemed the turbo timers were available and popular. However i never really let my engines run when i came to a stop on modern cars with Turbos, as i believed rightly or wrongly, that the car will cool enough on slow down miles before i switched it off anyway.

Now I am getting back to a turbo petrol car with intergrated water cooling in the exhaust side of the engine, with the potential to have VERY high heat spots in the cooling system without flow when switching off.  Is it something i need to worry about and do i need to let the engine idle? Or does the water pump run after the engine is switched off?

Or do i just drive and switch off?

Sorry if its been answered before

It's something I worry about, only the other day I was racing to beat the traffic lights,  they changed to red before I could get there I hit the brakes then the stop start kicked in killing the engine while the turbo is still spinning, I know back in the day this was a good way the kill a turbo.

Manual makes no mention of it, plus i am lead to believe the car has a built in electric pump to keep things running after you have stopped to prevent and issues.

As above it's taken care of on the Mk7. However after giving any turbo engine some beans it's worth just having 1/4 to 1/2 a mile sensible driving just to allow everything to cool down. No need to sit parked up like some do though, arguably with no air flow it's worse for the engine...
