Pickups Diesels Cold weather diesel issues

You are in the Diesels Forum. Your Host is kcram
I recently bought a 1995 international with a dt466, I am wondering about plugging it in in the colder weather, why is it done etc. ? And can you tell me about the water separator I don't know alot about the stuff, I've heard a little about them but don't even know if I have one on my truck. Any information to get me ready for winter would be helpful. I live in central wisconsin.

This is also a good check of your fuel supplier (gas/diesel station). If you see you are draining a lot of water regularly, the fuel you are buying has too much water in the holding tank and you should look for a new fuel source. A drop or three of water is not a big deal when draining the separator, but that's all. kcram - Pickups Host

| Can anyone help me? I have a 2005 Duramax and I have a K & N Cold Air intake. I recently have been having problems with it. It is running fine until I get on it a little or get up around 55-60 and it acts like it does not want to shift and makes a backfire noise or something. Then it shifts. I changed the fuel filter and it seemed to help a little but it still does it every once in a while. I took it to the local dealer and they said that it was water in the fuel. I drained the tank and used some supplement but still does not run right. Can anyone Help? Thanks | |

You'll need to get a service manual for your truck for the location and operation. kcram - Pickups Host

| I have a 2007 2500 HD duramax with 50,000 miles on it that has had a problem from day one that the local dealer has been unable to diagnose after running test and talking to GM tech support on mutiple occasions. They claim there is nothing wrong and that this issue may be inherent or possible caused by the 35" tires. My opinion is that the problem has to be caused by some kind of sensor issue. This is my third personal duramax since 2002 and I also have two others in my business fleet. I also bought another 2007 3500 at the same time. The problem has never come up with any of these trucks and I have had larger tires on trucks before. An finally the problem is when air temp drops below around 60° the engine really starts clattering or what could best be described as extreme detonation or spark knock and the colder it gets the worst it seems to get. When it is hot out you never hear a thing. You mainly notice it when at low RPMs, the engine is lugging and low turbo boost. Please help. | |

| Cranks fine when first starting then after driving about 15-20 min it won't crank until it cools off. | |
