texastrophies Posted December 7, 2012 Report Share Posted December 7, 2012 While driving my "Low Coolant" light flashed, I immediately glanced at my temp. guage and noticed it was starting to climb. Pulled over and called for help. My mechanic from work came and brought some anti-freeze. Put a gallon in and could not find any leak. Decided to get out of the 70 mph traffic flying by us, so I cranked it up and got off the freeway and pulled into a station with good lights. It ran fine. We started putting water in it and shortly after that the water came pouring out the back side of the engine it looked like it was near the top but couldn't tell for sure. It was not running at the time. It is an '06 Duramax. Left it parked, and went and got my trailer, cranked it up and loaded it on the trailer and took it home. Will hopefully get a chance to look at it early next week. Any thoughts? Quote Link to comment Share on other sites More sharing options...
Ravin R10 man Posted December 8, 2012 Report Share Posted December 8, 2012 Head gasket Quote Link to comment Share on other sites More sharing options...
texastrophies Posted December 8, 2012 Author Report Share Posted December 8, 2012 Don't think so, as fast as it is coming out there would have to be a hole in the head. With the engine off, we put a gallon of water in it, and within about 10 seconds it was all on the ground. The information I am getting online makes it sound like there is an o-ring for the oil cooler right above the oil filter that goes out. I am taking it in tomorrow for our mechanic at work to take a look at it. Quote Link to comment Share on other sites More sharing options...
LETMGROW Posted December 8, 2012 Report Share Posted December 8, 2012 Sounds like it would be something like an "o" ring or hose. Tough to say without a thorough look at it. There is alot of things in the way which might have to be moved to find the source. I really don't like guessing. I wouldn't get too excited until I knew for sure.

Ravin R10 man Posted December 8, 2012 Report Share Posted December 8, 2012 was the engine running when you added water? Chevy's are known for that head gasket failure..could be that O ring too I forgt about that Quote Link to comment Share on other sites More sharing options...
texastrophies Posted December 8, 2012 Author Report Share Posted December 8, 2012 No, it was off. It had been setting about an hour or so. Man, I hope you are wrong about the head gasket. I will keep you posted. Quote Link to comment Share on other sites More sharing options...
LETMGROW Posted December 8, 2012 Report Share Posted December 8, 2012 Check your warranty. Some of these had a 100,000 mi. powertrain warranty. Lynn Quote Link to comment Share on other sites More sharing options...
Shaun_300 Posted December 8, 2012 Report Share Posted December 8, 2012 Usually if it's a head gasket on a Duramax it leaks internally and puts pressure into the cooling system but you never know. One time the diesel mechanic in our shop took the cap off the surge tank and it sounded like a shotgun going off there was so much pressure in the cooling system. I agree with Lynn it does sound like some sort of a seal or hose issue if it's leaking out that fast. Quote Link to comment Share on other sites More sharing options...
texastrophies Posted December 9, 2012 Author Report Share Posted December 9, 2012 Check your warranty. Some of these had a 100,000 mi. powertrain warranty. Lynn I think it may be out at 238,000 +/- I hauled it into work this morning, but he won't look at it in depth until next week. Not real excited about it, yet. Really don't think it is a head gasket. It runs just fine, no smoke or steam out the pipe and the oil looks fine, also. I hear you about a lot of stuff in the way, we changed the glow plugs a couple months ago and found that taking the time to remove the inner fenders made the process a lot easier. Looks like we may have more the same this time. Thanks for the replys. I will let you know what we find and what it takes. Quote Link to comment Share on other sites More sharing options...
535hunter Posted December 9, 2012 Report Share Posted December 9, 2012 Idk if its like the equipment I have worked on but it just be a heater hose popped free. Either way keep us posted. Good luck hope its not to pricey. Quote Link to comment Share on other sites More sharing options...
texastrophies Posted December 10, 2012 Author Report Share Posted December 10, 2012 (edited) Preliminary inspection shows a busted water line that connects to some type of radiator on the top right behind and under the alternator. The hose is only about 3 -4 inches long and about 3/4" diameter. Looks like a lot of pieces have to come off to get to it, though. Dismantling has begun. Part is now off, hopefully it will go back together fairly easy. Edited December 10, 2012 by texastrophies update Quote Link to comment Share on other sites More sharing options...
texastrophies Posted December 10, 2012 Author Report Share Posted December 10, 2012 Fixed. Thankfully it wasn't anything serious. Couple hours labor and a few pennies worth of rubber hose. Quote Link to comment Share on other sites More sharing options...

Shaun_300 Posted December 12, 2012 Report Share Posted December 12, 2012 Glad you got it fixed up! And for cheap too. And yes anything on a Duramax is labor intensive! Quote Link to comment Share on other sites More sharing options...
