I have 2 questions about Turbo Cooling:

1) If I am planning on driving after a quick stop, as in just got off the highway to fill up and jump back on the highway, do I have to let the turbo cool for 2 minutes before I turn it off?

2) In cooler weather (such as winter: 35F) - Do I have to let the turbo cool for 2 minutes?


I don't have a problem letting the motor run for 2 mintues, I was just wondering.

Thanks

 

I think it depends on how hard you are driving the car. I remember there being a thread with pics posted of a glowing red turbo after driving on the highway.

1) If you have to get off the highway to fill up and take some side streets maybe a 1-2 min drive then you should be fine.

2) I live in Canada, normally I just make sure when I get a few streets away from home I take it easy on the engine.

There have been a bunch of posts on this issue - probably best to do a search.

If you are really concerned about it, you can always go for a Turbo Timer.

 

If you are driving your car hard than most certantly let your car cool down. In most cases normal driving for a few minutes after a good run is sufficiant enough.

 

I think if you are driving on the highway and stop to fill up you should still allow it to cool down a bit. But obviously if you were cruising at 2000 rpms it wouldn't be too much of an issue as the turbo wouldn't be THAT hot. But if you were cruising at about 4000 rpms then your turbo would be fairly hot and how long does it take for oil to get cooked in the turbo? Because as soon as you turn off the car the oil in the turbo is stuck there getting fried in that red hot turbo.

 

Yup. All the more reason to use synthetic oil (does anyone in this forum NOT use synthetic in a 1.8T???) and to wish the company had installed an electric pump for auxiliary oil circulation after key-off.

 

I use PAM!
