proper temp of turbo for shut down

[ralbert]

My daughter and son inlaw have just purchased a 2004 3500 and installed gauges over the weekend. Got a call tonight wanting to know at what temp it is ok to shut truck off. I waite to 300 degrees on my 99 but need the info on a 04. Thanks Rob

I shoot for 300* on my trucks also, probe is located pre turbo... . where it belongs !

I try to let it get down to near 300 also. Most often, with this '07 it's probably a bit above that mark, after around a minute or so of idle time and I just shut it down.

... groan.



The last couple days I've been running a Case International Magnum-series tractor, with the C8. 3 engine. It has an EGT gauge from the factory, and the probe is mounted after the turbo.

i have my timer set to 340. Sensor pre turbo in the EM.

If I have time I let mine idle til the pyro says between 350-375*F. Once in a while it gets shut down arround 400*F. I had my turbo off after running this way for about 3 yrs and it was clean as new in the cartridge. Even after the temp falls to below 350*F. after switching the motor off the temps will rise back up a bit.

FWIW, on my 05, I usually shutdown when the temp is in the 300* range.

The probe is pre turbo.

Havent had any probs.

:-{} Comparing a piece of farm equipment to a road vehicle is kinda like saying, grapes are fruit and so are pears. :-{} Think of the way these run, the tractor often will get set at speed and stay there for hours. The road vehicle on the other hand may have curves, hills, traffic or lights to deal with, some are used on the highway similar to the farm equipment. When I run farm equipment it is continuous and steady. When I run road equipment it is rarely steady state, EGTs can zip from 600 to over 1100 faster than you can say, "tractor. " I have never seen this type of radical change in a piece of farm equipment. The intended use is different and the need to closely monitor the temp preturbo just isn't there on the tractor IMO. Either position is useless if you don't know what to do with the information collected.

Like I've always said, if your goal is to protect the engine from melting down, the probe should be pre-turbo.

If your goal is to monitor turbo temperature for cooldown, the probe should be after the turbo.

Jeff, what is the usual pre-turbo running temperature on a tractor? With my very limited experience I've never seen one with a pre-turbo EGT probe. I would've figured depending on the implement and the ground conditions that pre-turbo EGT would vary about the same as a truck at steady-state towing a trailer.

When you're cutting a big field you want to plow as fast as the tractor can pull. So you are running at a heavy load all day and you want to keep a eye on coolant temps. If your tractor has a egt gauge I would keep a aye on it too. As far as cool down on a farm tractor you usually drive it back to a shed with out much load and it will idle while unhooking things or cleaning up before shutting down.
