How Do You Know If A Turbo Is Bad. Very similer to when I installed new injector in another. 2000 F-450 73 375000 Miles.

Look for a Check Engine Light on the dash. The primary function of a turbo is to make your car more powerful. Keep in mind though that a bad turbo on a turbocharged car is not the only issue that will cause a check light to come on.
Its important to know the reason why the turbo failed because you may fit a new or refurbished turbo that could fail through an underlying fault.
No codes thrown either. 2000 F-450 73 375000 Miles. At 70000 miles it needed a sensor for the exhaust and I had to start adding coolant monthly. I did refill the engine and did start but smoked white.
