ok ive been looking and searching but just dont have a clue.

i should go to the dealer and get the high idle enabled right?

i read to put your truck in nuetral when letting it warm up?

when i get out of a store for instence how long before i can start driving? do i have to wait for the lights to stop dimming and volts going up and down??

and if there is anythign else i should know

thanks i have a automatic trans

 

1 yes
2 yes
3 Let the engine build oil pressure then drive.

 

Well first off I have the Mopar cold weather front, install it when temperatures stay below 50*. I plug my truck in at night with a timer also. I do not have the hight idle enabled and really don't think it's necessary IMO. In the manual it warns about idling in cold temperatures. The fuel doesn't burn as well and tends to wash into the oil. I have my oil analized every 4000 miles and it will show fuel in the oil ( winter months) but nothing abnormal. I just start it up and start driving, I stay light on the throttle till it water temperature gets to 200*. I think some say to keep RPM's below 2000 till warmed up. A cold engine will warm up faster when under a load that is why I just start driving after starting. Keep in mind this is my first diesel and have had it for two years now, so I am not an expert. But information from this site has helped me a lot.

 

I think they all should have a manual high idle feature.Its not just for cold temps but hot also.Makes a more compleate burn of fuel,keeps temps in check in hot or cold weather.Use or drive a tractor or other diesel equipment and see what a big differance a cold start is after firing it up and then ramping it up to 1200 rpm. Goes from chugging/smoke etc.to a nice even run.In hot weather after running max or near max rpm and stopping it aids in cooling it down and heat evening out through the engine instead of hotsopts.On our trucks you can leave the dog inside it,ramp it to 1200,lock the doors and not worry about cylinder wash or it loading/carboning up as much as it would at a low 750 rpm.

 

An oil pan heater on your engine AND your trans would be great...

 

cool thanks for the info guys i really appreciate your time im new to the diesel world and appreciate the help

 

My truck has an automatic high idle feature. I am not sure if it is only on Canadian trucks as everyone here talks about the manual high idle via the cruise control that can be enabled by a dealer. If cold, my truck idles up to around 1000 rpm's and then idles down when the coolant is at the appropriate temp. It may do this several times over an extended period of time.
If you need to have your truck idling for more that 5min. then the high idle feature would be good as it helps avoid cylinder washing with unburt fuel.

 

hey guys i just got back from the dodge dealer.i had them enable my high idle.i bought my 04.5 h.o. in houston and drove back to canada.it seems to be a good feature.select cruise hit the set button and she goes to 1100 rpm,if i want higher rpm i just hit the acc. button.

 

They ALL have the automatic 1000 cold rpm feature starting in 03.

 

You don;t say where you live, but consider getting and installing the cable for your block heater... it's located behind the oil filter. Did mine 2 weeks ago, man does it make a huge differnce on cold morning starts. Have it on a timer, turns on about 3 hours before I start it.

 

I think this is exactly the point of the High Idle feature. It runs from 1100-1500 RPM and puts the engine under a user controlled light load so you specifically don't have issues with wet stacking.

 

I noticed in your tag:

Computer Enabled Options - Power Off Delay.

What is that one?

I had also heard or read that there is a speed limiter setting as well?

Had my manual high idle enabled as well, service manager had no clue what I was asking for... at least the tech understood

 

Something else that hasn't been mentioned...

If you have an exhaust brake, turn it on once the oil pressure has come up and stabalized. It bumps the EGT's up a couple hundred degrees while you are scraping the windshield or whatever, and it will defog much faster (especially if it's doing the fast idle thing).

Also, if I lived where it got down to negative double digits often, I'd likely run lighter weight synthetic oil for better pumpability.

I also subscribe to the let it idle for a couple minutes, and drive it mellow until warm school, along with using the block heater when it's below freezing, and a winter front when it gets down around 0f.

 

Wouldn't the hight idle feature be used for someone (like a delivery person) who may be getting in and out of the vehicle before getting warmed up. I really just get into the truck to get going somewhere and want to move (however slower when cold). I would think geting the truck up to temperature would be better IMO, just fast idle can't warm up as fast as, could it? Am I wrong of is this just splitting hairs. I am courious (sp) on this.

 

If you notice most of these Ford Resque vehicles are high idling at Waffle house and such in the parking lots while crews eating.They don't turn them off during shifts.
