Have a new 6.0 crew king Ranch on order..never had a diesel truck before..will be towing a 30' Citation...8000 pounds wet weight.....am confused about a couple issues..(great forum)
1)_ where can I get the pillar post 3 gauges for "pyro,.turbo, auto trans temp...( in Canada) and how much $$$ to buy and install...they seem a good investment???
2)diesel starting /idling..some posts seem to say " start your diesel truck and limit your idling to just a couple of minutes at most and slowly drive off..once warm...normal ops.prevents "STACKING "ON VALVES
THEN WHY DO THE BIG DIESELS IDLE FOR HOURS AT TRUCK STOPS?
3) when you shut down..check turbo temp and let cool before shutting down..how can you tell temp w/o aftermarket turbo temp gauge ?
4) what are the pyro, turbo , auto trans .."redline numbers"
Letting a diesel idle for a long period of time is not good at all. A diesel engine will drop it's temp at idle below optimal running temps thus cause premature wear & tear. It's good to warm up when first starting but not to let it run too long. Unspent fuel can load up and actually fuel-wash the cylinders. The loaded up unspent fuel will also cause "black stacking" which is a large gust of black smoke blown out of the tail pipe. This can sometimes make a diesel run rough until all of the unspent fuel is blown out.
Most of the diesels that you see parked at idle have some type of apparatus that raises the idle to a higher rpm. This allows the engine to keep the running temp up to normal.
It's always good to let a diesel run for a few minutes after running it to allow for the turbo to cool down. Most people will let it idle for a couple minutes just for cool down then shut it down. This is normally after a hard or long term run.
Diesels do like to run and run for long periods of time but just to let it run at idle for a while really has no purpose. Jake.

Are you sure you have enough truck for the trailer you are pulling what does the 30' Citation weigh you might be overloading the truck. I'am a fellow B.C.er and you don't want tobe overloading the truck with a trailer you will run out of brakes those trailers brakes have tobe perfect working order. I know one thing you wouldn't want togo on the killer road going into Bella Coola Valley my uncle used to live there no he lives in Williams lake.
JAKE is right about idling diesel trucks its not good for them you let the turbo cool down a bit by idling the engine for a minute or two and shut the engine down. A diesel engine isn't going to stay any warmer idling at a low rpm compared to it being shut off there should be no worries about starting in the cold.
You will definatly need a pyro it measures the exhaust temps if it starts getting over 1100 you will melt things it means your pushing it too hard so take your foot out of it.
To find some gauges look here www.bd-power.com a place in Abbotsford that carries lots of good stuff for newer P/U trucks.

The simple answer is they don't. More specifically, if they are idled for extended periods, it's done using an auxillary idle control that raises rpm in order to maintain engine temps. If it's real cold out, you may see trucks running, but more likely you're hearing the auxillary heater (ProHeater), a small diesel engine that is used to warm the engine coolant and the cab during cold weather stops.
when you shut down..check turbo temp and let cool before shutting down..how can you tell temp w/o aftermarket turbo temp gauge ?
You can't. Watch your engine temp gauge. The key to this is to allow the oil to circulate through the turbo to to cool it. If you shut the engine off immediately you have a hot turbo, still spinning at very high rpm, with no oil flowing to cool or lubricate it. It's a real quick way grenade your turbo. Let the engine return to idle speed and run a minute or two before you shut it off, especially after a long, hard run. A pyro is the best way to measure engine temp and ensure max. life.
Kenworth..have lived and worked in Williams Lake for 24 years( Paramedic)..may know your familly? My travel trailer is rated to weigh7700 pounds..probably 8500 wet going to the lake..the truck is 9900 gvwr and probably is going to be 8500 "on the road".. so truck and trailer are about same weight roughly.. my last truck was a gasser 1997 Ford f-250 light duty gvwr 7700 pounds had 5.4 motor auto trans with3.73 rears and it pulled the Citation no problems..now I am going 1 ton srw new 6.0 turbo diesel with tow/haul trans..3.73 rears and rated for 12,500 pounds towing..what more can I do?? going with the 3 gauges pyro/trans /boost to watch how things are doing..and by the by the old 97 gasser took that trailer in and out of BELLA COOLA several times no heating no problems...let my know..
Thats no problem pulling 8500lbs the trailer must be a lighter constructed unit or I have my thoughts on what a travel trailer weighs out of whack. The thing you need to watch when towing is the Pyro,Boost, Engine temp and if you get a gauge for the automatic you keep a eye on that.
Supposidy the new 6.0 is better than the 7.3 I haven't seen one yet but I would like to I'am usually not a beleiver in getting more power out of a small engine but gotta trust International on this one.
I never been to Bella Coola my mom and my other aunt have gone to see their youngest brother when he lived there and I heard about the road going into the valley is pretty scary with all the switch backs and narrow lanes.
Good Luck on the truck I hope it works out for you.
Srupp,
In all things moderation! Idling won't hurt your engine as long as it's not excessive (5 or 10 minutes at most). As for cooling down the turbo it's not turbo temp that your worried about. This is a misnomer. If the engine is shut down right after a hard pull the turbo is still turning very quickly. Many thousands of RPM's. When the engine is shut down now the turbo has NO lubrication. This prematurely wears out the bearing and will ruin the turbo. This can in turn ruin the intercooler and ultimately in extreme cases the engine. It's worth 2 or 3 minutes of idle time to slow the turbo. Even under normal circumstances when you shut the engine down you can hear the turbo wind down. This is normal. I worked as a journeyman diesel mechanic for 17 years with the last 8 years being for the International dealer in Portland Oregon so take it for what it's worth. You say you are a Paramedic? Thats funny. I have been a paramedic for the last 12 years. I live and work on the North Oregon coast. EMS is a small world isn't it?
My 6.0 has an automatic idle adjustment feature. After idling for about one minute, it automatically kicks into a higher idle. I assume to keep the engine at temp.
As far as waiting before you turn it off, I never seem to have that problem. By the time I pull off the road, find a place to park, and park, the truck has idled for some time anyway. I would follow your advice and idle the truck if I ever had the reason to pull off the highway such as an emergency, and shut down.
No need to worry about the newer fords left to idle they all have an idle gizmo in the cold that kicks the idle up to prevent any problems.Such as wet stacking. My brother lets his sit all day at times when the temp gets low the idle goes up automatically to raise temp and then goes down when its up to temp. Most big rigs are setup to do that now also. At our local truck stop they never shut em off...
