Thanks, I took it to had it at Northwest Freightliner in Palitine,Il and they put it on the machine. Was not the turbo, but a sensor that was faulty. The truck would loose power from time to time and wouldn't get over 45mph. I hope this is the last of my problems with this truck. And,the moter is cat 3126. Thanks for the info Larry

If one ever needs to be replaced, turbos cost between $500-700.
Get maximum turbo life by letting your diesel idle for 2 or 3 minutes after running before shutting the engine down. This is not to let it cool, as some think. It is to let the impeller slow down before stopping the engine and killing oil pressure. The impeller spins upwards of 100,000 RPM during operation. If left spinning without oil pressure to its bearings, the oil left there "cokes" or heats up very quickly and turns into solid carbon which eats up the bearings quickly.
Another thing I see kill turbos is small leaks in air intake hoses that let dirt in to bend impeller blades and kill it that way.
Turbo problems, unless related to the wastegate, are rarely intermittent- when it dies, the engine will have no power and pump out a TON of black smoke.

Very good advice from Weave,I have had 3 trucks and all went over 700,000 without turbo problems.I religiously idle for at least 5 minutes before I cut the engine off,especially if I have been running highway speeds. Now after I bragged I will probably blow the turbo tommorrow.
