“USIZIME IMMEDIATELY”😮‍💨 Why you should let your turbo-charged Engine cool down for 3 minutes before shutting it off after a hard-drive.

Then why did they install an iStop?

This is about hard driving,after like 250kms and above,for the istop to function,you must be in a traffic jam or completely slowing down,so it will have cooled down before ut shuts off completely

Most modern cars with turbos have systems to cool the engine even after it's turned off. Letting the car idle for a minute or two after a long drive is good but usually not needed especially if you run on superior synthetic oil.

Eric,true that,but it was about turbo cooling,engine is all good

From my experience, you can leave the engine run even 5mins. Have you wondered why buses or trucks are left to idle for a longer duration even 15+ mins?

Hello sir,same concept☑️

How does a running engine cool? A running engine heats up

It cools by letting the oil pass kwa turbo taking away the excessive heat

Most modern turbos are water cooled and have no need for this procedure. '...water cooling eliminates the destructive occurrence of oil coking by utilizing the THERMAL SIPHON EFFECT to reduce the Peak Heat Soak Back Temperature on the turbine side piston after shut-down...'
