You should let your turbo cool down for at least 5 minutes after driving before turning off the engine. This will help prolong the life of your turbo and prevent it from over heating.
If you’ve ever driven a turbocharged car, you know that they require a bit more care than your average vehicle. One important thing to keep in mind is how long to let your turbo cool down after driving.
Most experts agree that you should let your turbo cool down for at least 15 minutes after driving.
This gives the engine and turbo time to slowly cool down and helps prevent any damage from overheating.
So next time you’re done driving your turbocharged car, be sure to give it a few minutes to cool off before turning it off. Your engine will thank you for it!
5 Things You Should Never Do in a Turbocharged Vehicle
If you own a turbocharged vehicle, there are a few things you should never do if you want to keep your car in good shape. Here are 5 things you should avoid doing:
1. Don’t turn off the engine immediately after driving – Let the engine cool down for a few minutes before turning it off.
This will help prolong the life of your turbocharger.
2. Don’t start the engine without oil – Make sure there is enough oil in the engine before starting it up, or else you could damage the turbocharger.
3. Don’t let the car idle for too long – idling can put unnecessary stress on the turbocharger and shorten its lifespan.
Try to avoid letting your car idle for more than a minute or two at a time.
4. Don’t use low-quality fuel – using lower quality fuel can lead to deposits forming on the turbine blades, which can eventually lead to turbo failure. Stick with good quality gasoline or diesel to help keep your turbocharger healthy.
5. Don’t forget about regular maintenance – just like any other part of your car, regular maintenance is important for keeping your turbocharger in good condition.

Do You Need to Let a Turbo Cool Down?
Yes, you need to let a turbo cool down. If you don’t, the heat from the turbo can damage the engine.
How Long Should You Idle a Turbo before Turning It Off?
When you’ve been driving your turbocharged car around, you might be wondering how long to idle the engine before turning it off. After all, those turbos can get pretty hot after a hard day of work.
Here’s what you need to know: it’s generally recommended that you idle a turbocharged engine for 3-5 minutes before shutting it down.
This will help the turbo cool down gradually and prevent any potential damage.
Of course, there are always exceptions to the rule. If your car has been running particularly hard or is significantly hotter than usual, you might want to give it a few extra minutes to cool down.
And if you’re really in a hurry, 1-2 minutes of idling should be sufficient. Just keep in mind that doing this regularly could shorten the lifespan of your turbocharger.
Should You Let a Turbo Diesel Cool Down?
It is generally recommended that you let a turbo diesel cool down before turning it off. This gives the oil time to circulate and cool the turbo, preventing premature wear.
How Long Does It Take for a Turbo Diesel to Cool Down?
It takes a turbo diesel engine longer to cool down than a gasoline engine because the turbocharger is located between the engine’s exhaust manifold and the atmosphere. The turbocharger forces more air into the combustion chamber, which increases the temperature of the exhaust gases. These hot gases can take a long time to dissipate, which in turn keeps the engine warmer for longer.
Always WARM UP & COOL DOWN your TURBOCHARGED Car
Conclusion
It is important to let your turbo cool down after driving. You should let it cool down for at least 15 minutes. If you don’t let your turbo cool down, it can overheat and cause damage.
