Letting the Turbo Cooldown vs Just Shutting the Truck Down.

Is there a Pyrometer in the gauge cluster? We had timers & set it for 3 mins.

 

I don't shut down until the pyrometer hits 300*. During the winter it's usually already there by the time I'm off the highway and backed into a spot. During the summer it can take 3-5 minutes after parking. I personally high idle with the fan on to get there because I hate low idling an engine, but low idling works just as well for the turbo.

The reason you need to do it is because if the turbo is 600+ degrees and you shut it down the oil left in the turbo is going to be super heated onto the turbo bearing surface which will lead to premature failure.

 

Same procedure here.

 

Couple of minutes and shut it off. Once the pyro has dropped back.

 

I sure wish I could find shut down timers (mechanical) to purchase. I had them in trucks previously and used them every time.

 

I always idle for around 5 min after I park t9 let everything under the hood cool down and stabilize. It's better for the turbo and all the rubber hoses
