    I usally dont plug it in unless it gets below 30 degrees, but even at 30 its LOUD upon first start up. All the guys at the shop are giving me a hard time because their PSD and Cummins dont do it. Is mine worn?? or is this normal. I cant seem to remember from my days in the motor pool.

    BTW--97 GMC K2500 6.5 TD I use Rotella synthetic oil changed every 5000 miles. it has 79000 on it.

    Thanks rob

    we haven't ever plugged in our D/A...and notice when it gets chilly- below 20 it's loud for a about 30 seconds upon start up, almost crackles- I kind of like the sound of it.... One of John's workers has a 98 6.5 and he doesn't plug it in either, he said his is loud...

    We currently have a Cummins and a PSD in our fleet, both are '01's and they are loud when the start up in the winter- and those two get plugged in...

    The Cummins and PSD will start easier in general because they're direct injection engines indstead of prechamber diesels like yours. I don't know about the PSD but I've heard the Cummins will start unaided, without glow plugs or grid heaters down to 40 degrees. The 6.2 and 6.5 definatly will not.

    I'm not sure about the PSD and Cummins, but the GM diesels advance the timing quite a bit on a cold engine. The colder the engine, the more racket it makes when started cold. I think it's pretty cool. I wish mine sounded like that all the time!

    The cummins and psd don't start very easy AT ALL in the winter unless they are plugged in, sometimes the plug cycle for about 15 seconds prior to the "okay to start" signal. The longest the D/A has cycled is 6 dings on the door chime...after the 6th ding- the light it out and she starts up...I LOVE the way mine sounds cold...also like the whine the allison has when she's cold....wish it stayed that way!
