How long should you wait to turn off a turbo car?
When you drive it gently around town, 15 seconds should be more than adequate. When you drive the car hard ie. when your husband drives it, you should let it cool for 30 to 60 seconds.
Why do you let a diesel idle before turning it off?
Dan explained how you must let the engine idle a while to cool down after any long haul to prevent the manifold from cooling too fast. The exhaust manifold gets hot, really hot on long trips, especially those over steep mountain passes. In short, the quick cooling will end up warping the manifold.
Is it bad to idle a turbo car?
But due to high inertia, the turbo shaft will keep rotating, without lubrication. Again the bushes will wear out and oil consumption will increase. So its always recommended to leave a turbo-charged vehicle on idle for a little while after starting and before stopping.
Is it bad to rev a turbo car?
It does not matter if the engine is naturally aspirated or turbocharged, a cold engine should not be revved hard. In turbocharged engines, the damage can be much more. The engine oil lubricates the engine and keeps it safe from any wear and tear.
Is it better to let your car run or turn it off?
Unless you drive a vintage, carburetor-equipped vehicle, you’ll save fuel and reduce carbon dioxide emissions by turning it off. Some drivers think that idling uses less fuel than restarting, but our research has found that drivers save fuel and reduce emissions by shutting down for stops as brief as 10 seconds.
Do I need to let my turbo diesel cool down?
You don’t need to cool the engine before you turn it off, but you should cool the turbo if there is one fitted. The turbo runs very hot due to the exhaust gasses passing through it. If you turn off the engine while the turbo is still hot the lubricating oil which is normally fed by the engine oil pump stops flowing.
Why do truckers leave their trucks running all night?
Truckers, both independent owner-operators and fleet drivers, leave their engines idling for three main reasons: weather conditions, economic pressures, and old habits. In cold weather, a truck’s engine and fuel tank need to stay warm.
Can you disconnect turbo?
There’s no concept of “disconnecting” the turbo as it’s an integral part of both the exhaust and induction systems, so the short answer is NO. Longer answer is that you would have to remove the exhaust manifold and turbo and the first section of the exhaust system and replace all of it.
Do you need to warm up a turbo car?
Yes, turbo chargers in themselves need to be warmed up before driving and cooled down after driving. This is to save the bearings in the turbo assembly from deforming. Turbo chargers function at very high rpms, mostly in excess of 100k rpm. As a result, oil temperatures are quite high.
What happens if you turn off the Turbo while engine is running?
This will allow time for the oil to cool down the turbocharger while the engine idles down. If you were to rev up your engine and then shut it off, it will cause damage and wear to the turbocharger as the oil pressure drops with it is still spinning at very high RPMs.
Why does my car idle for 30 seconds before turning off?
Idling the engine even for 30 seconds before turning off engine allows the cooler idle exhaust and cooler idle oil to bring the temps down in the turbo enough to increase the life of the oil. This is also one of the reasons many people specify full synthetic oil.
Why is my turbo running so hot when idle?
The turbo is lubricated by the oil and runs extremely hot. When you are driving (above idle) the turbo runs hotter than it does at idle. The very minute amount of oil that remains inside the turbo bearings after shutdown effectively gets cooked since it is no longer circulating to and from the oil supply.
How long should I let my Turbo idle after stopping?
If you’ve taken a mid-way stop during a hard highway drive, it wouldn’t hurt to let the turbo idle for an extra minute. The holy grail of reliability – Toyota – recommends up to 2 minutes of idling after continuously driving at 100 kph, as does Skoda for the Laura.
