I searched for a "rule of thumb" on cool down periods but like other things everyone has a completly different opinion. I was wondering how long I should let my car idle after normal stop and go conditions or maybe little spirts of speed here and there. I live in the valley where temps are between 60 and high 90's during the summer. Some people say under normal conditions 30 seconds to 1 1/2 mins is enough. One guy said he let's his idle for 9mins! Can you help?

 

i also had this debate with myself.. so i bought a turbo timer and just set it for 2 minutes, this way i dont gotta wait around , although i think 1 minute would be enough i just wanna be safe

 

Yeah I've heard two very different sides to this topic. I've decided not to buy one. I still might change my mind though. One of these times I'll be in a hurry and wish I had one but I guess I'll just be late. Thank you for your advice. I know what you mean about wanting to be safe. Take care.

 

Buy one man. When your turbo runs hard and you shut off your car. The oil does not circulate through the oil cooler any more. The heat generated from the turbo can cake the oil allowing it to resisit flow. This can screw up oil passages, the turbo, and even the engine. its not a bad investment

 

hey thanks. That's a really good point. I think you changed my mind. I'll go ahead and buy one anyway. They're not that much so it's not really that much of an investment then is it?

 

If you've been floging it 2 minutes is enough time, if you were running low power and rpm for at least 2 minutes before to stopped, just turn it off... Turbo timers ARE worth the investment unless you don't mind sitting and waiting EVERY time you need to.
