If you are on the eastern side of Washington then yes you will need to plug it in. Temps in the teens at night this week. Ahh here comes winter. I have mine on a timer and set to come on 3 hours before I leave for work.

 

mytrook....i'm on the west side...a little south of olympia on the I-5. it's been cold here but not into the teen's kinda cold yet. i'm thinkin i may invest in a timer just to help get things goin in the morning....even if it's not completely necessary. thx.

 

I would take JohnsDiesel's advice, it is not no big thing. I am from Southeast Idaho, once it gets to about 20 degrees plug it in. If you have a timer than its just a plus, you don't need to have it plugged in all night, but if you do, it is not a problem and it won't hurt you or your truck. It just saves on your electric bill and is alot easier on your starter (that i heard is expensive)! Also a little bit of Howes Diesel additive for those cold winter days would'nt hurt either, it is an anti-gel and helps with water in your fuel. Just my $.02's

 

Ok

I am new to this forum but not new to diesel. The cold morning noise (similar to a hissing sound) is the EBPV. It's sole purpose is to restrict the exhaust gasses to speed engine warm up time only to increase cab heat up time. It is there for your cold weather comfort. It acts as an engine brake unless you step on the petal then it comes off allowing free flow of gasses. You don't really need it unless you don't like to sit in a cold truck. You can disconnect it (only plug on the side of the turbo) or you can rewire it with a switch in the cab to create your own engine break.

You should plug your truck in when it is cold (freezing or below). I live north of the border so to me that is zero. I rarely plug mine in and when I am hunting up north it will dip to -40 degrees C. It is a little grumpy to start but it will. It doesn't like to run until it gets some heat in its bones. Make sure you use winter diesel in that kind of cold. DO NOT LET IT IDLE TO WARM UP!!!! Unburned fuel washes the cylinder walls of the lubricating oil which is not a good thing with low sulphur diesel. No oil, no lubrication and scratchy, scratchy rings on cylinder walls. You won't get more than 400,000 miles out of the thing.

Friends in the far north put on about 70k miles a year and they all run the idle control at about 1500 RPM.

You can leave it plugged in all night if you don't mind paying the power bill. Buy a timer.

Good luck and happy dieseling.

 

THANKS---This hiss sound will stop and start like every 5 to 10 seconds ??? as you tried to accelerate???----what it was doing was not a solid type noise,--- is this what a exhaust valve would sound like?? But the one thing everyone is saying is to drive off, not to let it idle, and that is what I always do, not a big one for just letting a vehicle set and run.

 

The hiss is present on deceleration and constant rpm. The EBPV will open on acceleration to allow the exhaust gas to move freely causing the hiss to stop. Watch the temp guage and you will find (providing the guages do act the same) that the hissing will go away when the needle reaches the second veritcal line.

 

Silence: I think I might have the same problem that DANDYoDAN had. Except when I drove to work this morning the engine was warmed up and it bogged down and made a hissing sound. From reading all the replys in this post it sounds like my back pressure valve is stuck. Cause it goes away when I hit the gas, but comes back again. Can someone confirm my suspicions? and how do I fix it besides disconnecting it? thnx

 

this thread answered my question Now Ill have to watch the temp gauge to see that.
