    LMM: Glo plugs

    Using right and left in many cases is problematic. Drive down the road and take 2nd drive on right. Well, what if you're coming from the other side? Same directions apply? Right and left on a car? Same problem, although there is a presumption about what is meant, IF YOU KNOW ABOUT THAT...

    '09 First fluid change, heavy towing

    Larry You have to watch those descriptions very carefully. I would make sure it says SYNTHETIC and it should say Mobil 1 and TES-295 approved. There are some similar descriptions in advertisements that may not be what you want. If there is ANY DOUBT, call the seller and find out. I't's...

    LMM: Mileage doesn’t make sense

    Lots of fans of 'hand calculating' mileage. So what is it that the truck doesn't do correctly when tuned? Fuel used? Mileage? Calculation? I've asked this question on several discussions, never a direct answer. I'm sure there really is one.

    Coolant pipe coating

    From your picture, I thought the WHITE stuff is what you were concerned with. I have no idea what the black stuff might be. Only thing I can think of being black is from a head gasket leak.

    Coolant pipe coating

    Looks like scale from hard water to me. I grew up in AZ and our water was very hard and everyone's radiator and hoses looked like that. Use a heavy duty cleaner in the cooling system to remove the scale, flush 3 to 5 times with Distilled water only, then fill with coolant and distilled water...

    LMM: Trailer brake issues

    First things first: 1) check truck's output to make sure you have electricity at the truck's receptacle 2) check the trailer by ohming out the circuits like 2004LB7 posted 3) if both check out, what's left? The connector.

    2005 Duramax starts and shuts off within 5 seconds

    When your engine turns off, is this because the key is no longer in the start position, or does it run for a few seconds while in the run position? If your battery is being drained, perhaps starting there is a good idea.

    There are several reasons for this code, including worn injectors returning too much fuel, restrictions on the fuel supply side, pinched lines, dirty tank, dirty filter, etc. If your problem seems to be more prevalent with a low fuel tank, it could be the dirty pickup problem. If same happens...

    2009 LMM Lift Pump Install

    Possibly the best thing for a diesel engine is plenty of CLEAN diesel fuel. I would never bypass the stock filter, now that you have a lift pump. If you don't like dealing with the WIF sensor, just unplug it at the electrical connection but leave it attached to the filter. I have never had a...
