    Update: I was pulling my travel trailer (32' 9k) up a 4 mile upgrade (maintaining 60 mph) over Easter outside temp was about 75-80. My temp gauge went past 210 by two of the marks. I pulled this same trailer with my 2005 3/4 ton suburban up the same grade many times and never had it get that...

    Knocking and blowing black smoke then white

    Update: So far so good I have put about 300 miles on it and it seems to be running fine. I still can not believe that just dumping a can of additive in the fuel tank was the fix.

    Knocking and blowing black smoke then white

    Update I picked the truck back up last night. The new shop they took it to said that they can find nothing wrong with the truck. No codes and seems to run good. They also did a coolant dye & press test and a injector cut out test no problems found. They put a can of fuel treatment in it and said...

    Knocking and blowing black smoke then white

    Update: They have now had the truck for 6 days. They now say that it might be a injector problem and they want to send the truck to another shop to have them check it out. They say there tech is not able to do anymore. I thought all the injector problems were with the early duramax engine (lb7 I...

    Knocking and blowing black smoke then white

    I told them this morning that if they can not find a problem I want it in writing that if there is a problem in the next several months that they will fix what ever it is free of charge to me. I did not get a straight answer back from them yet. I am also thinking I may take it over to my local...

    Update: The used car dealer has had it for two days now and they have not found any problem. They say the truck is running great and having no problems for them. They are keeping it for one more day at this point.

    No I have not checked anything at this point. I called the dealer I bought it from and they asked me to bring it back over to them tonight. so I just night dropped it for them to check out Monday morning. They are a used car dealer not a gm dealer so I want to make sure they do not feed me some...

    Temp Gauge fluctuate's

    Thanks! It sounds like it is not that big of a deal at this point. I will wait and see what happens when it gets hot around here.

    Temp Gauge fluctuate's

    I have a 2006 2500HD LLY It is new to me and I have noticed when driving around the engine temp gauge fluctuates between 180 mark and just under 210 mark. It does this even when I am not hauling anything. It also takes a long time to warm up. The heat works very good it just takes a while. I...

    I have become a new owner of a 2006HD LT crew-cab LLY Duramax Allison 6 speed. Found this forum to be very good at giving me answers to some of my questions about the truck. I am in the mid atlantic area and will be using it to haul our 32' travel trailer around for the most part. This is my...
