How long should I wait for the cooldown when I idle before shut off?
On a modern vehicle, about 0 seconds.How long should I wait for the cooldown when I idle before shut off?
I can’t see what vehicle you’re asking about.How long should I wait for the cooldown when I idle before shut off?
Early 80s and 90s vehicles tended to use bushings instead of bearings for the turbo. Add that alot were air cooled not water cooled hence why many people put turbo timers on their vehicles. If the vehicle was turned off without cooling down you could get coking on the bushings.On a modern vehicle, about 0 seconds.
- they will be designed for either passive cooling techniques or run a small pump
- the last few minutes into a residential area are usually pretty tame
- with as many turbos as there are out there now, there would be widespread knowledge if this was a problem.
the cooldown problem stems back from the 80s when turbos were new and add-ons didn’t have the engineering we have today. Or maybe (I have no firsthand experience here) if you are bringing the car in off a hot lap at a track.
OR (I do have experience here), if towing heavy and they are barely glowing soft red, 30 seconds off the interstate. In that case I’ll let it idle a few minutes.
Doesn't matter. This issue is taken care of in modern turbo motors.What car? lacking that information 0-300 seconds depending on how it was driven in the last few mins before idling.
they usually either do it by convection or with an electric pump.I thought newer turbos run coolant through them on some sort of thermostatic switch so the turbo can properly cool.
Gas engine egtd don't really cool down. Hooefully it has coolant surrounding the bearing.How long should I wait for the cooldown when I idle before shut off?
No, not always. There is a guy who rebuilds Mini Cooper turbos and he said he gets a high # of them with coked turbo shafts, some really bad ones. They are water cooled and I can assume the extreme Mini's, the owner's know how to babysit their turbos. Yet he still gets coked turbos in on a regular basis he said. He is an advocate of cooling down "pushed" turbos.Doesn't matter. This issue is taken care of in modern turbo motors.
