Hour meter.

[BrokenBoots]

I know they're on diesels but I have on on my 8.1 gasser too.

 

I guess it was easier for GM to use one display instead of making two?

I think the hour meter is one of the calculations used by the computer to determine when you're due for an oil change, so it's in all of the trucks.

the hour meter has been on all the 99+ trucks (i dont know if the 4.3s have em but the 4.8, 5.3, 6.0, and 8.1 all do)

Shazam. I had an 02 2500HD and never noticed an hour meter.

Yep..my 2002 HD has one too !!! - Its actually kinda cool !!

 

 

Remember our fallen heros !

Me neither! Where is the hour meter on my 02 2500HD CC 4x4? Or how do you access it? Through a computer scanner or something?

 

I know the 03 Z71 my buddy owns has that computer deal on the cluster. 

 

thanks.

Just hold down the button on the odometer for several seconds. The hours should pop up.

Wow, I'm going to go try it now... Although it was 75 degrees yesterday, its 28 out now and my truck is covered in ice and it's sleeting. (Thats central Texas' snow, maybe once or twice a year)......

 

 

.....OK back. #### its cold out!   Took 5 minutes to get my door opened!

 

I Tried everything and couldn't get hourmeter to  work. Truck on, truck off, in-gear out-gear, push 4 times like headlight override, nada. 'Bout to give up and you have to turn off engine and put in accessory postion and then hold it down!!

 

Cool!  672hr in exactly a year. Only 15,xxx on the truck so I guess not too much. Averages to about 23 mph. Or 1.8 hours a day in the truck.

 

Thanks for the cool new feature.  :thumb:

I guess we coulda been nice and mentioed that it is with the key off, or even removed.  When the odometer is dark push the trip button...miles will  appear, if you hold for about 4 seconds hours will appear.  I fyou try this with the key on you will reset the trip meter. (Oops!).

28 degrees cold?

 

Id take that over the blistering 5 degrees (minus 10 windchill) this morning

 

last friday it was 55 (rare warm day)

Yeah, found that out this morning. Hourmeter Works w/ key off or in acc.

 

Kinda joking about the temp here. The city is basically shut down! Still 28 at 1pm, and all schools closed, and a lot of major buisnesses! I did slip on my a$$ going out the front door.    But only 1/2 inch of ice pellets on the ground and road for the most part are fine.

 

I grew up in MD and it was sweet, we weren't far enough north to have all the plows and stuff so when the 1/2" snow came got out of school.

 

 

Anyways thanks for the info on the hourmeter.

Does anyone know how the hour meter works?  I have heard that an hour meter does not really work in the sence of 60 minutes equals 1 hour.

 

For instance, if your hour meter was brand new and read 0 hours and you started your truck and drove for 1 hour, the hour meter might show something like 1.75 hours.

 

Anyone know if this is true?

 

Thanks.

I'm not sure what they use on the pickups but on tractors, I think the engine hour is based on one hour of operating at 1750 RPM.  If the motor is running slower than that, it will take longer than 60 minutes to make an engine hour.  If your runnning faster, you'll get an engine hour in less than 60 minutes.  Really it is a measure of total engine revolutions in a certain number of hours rather than a measurement of time.  It is also a better method of determining when to service the engine than miles.  That said - does anyone know how often (in hours) a truck engine should be serviced.  I am guessing around 150 - 200.

I record hours and gallons after every tank, and it seems to me that the hours recorded are the hours in clock time that the engine ran....when went roaring across Wyoming into the wind the meter clocked up 4.6 hours (265.8 hours/10,456 miles in Longmont,CO and 270.4 hours/10,780 miles in Rock Springs, WY) 70.4 MPH and 19.7 MPG.  The times on the pump receipts are about 5 hours and  20 minutes apart...did I mention we stopped for Breakfast at Johnson's Corner near Loveland, CO?...Highly recommended by the way....have the Cinnamon Roll...:thumb:

 

4.6 hours = 4 hours and 36 (+ or - 3) minutes...44 minutes for breakfast sounds about right to me.  

 

Now on single engine airplanes there is an hour meter built into the tachometer, and it really records engine revolutions instead of time....only corresponds to actual time when running at cruise RPM.  Some of them also have a "Hobbs" hour meter which in signles is usually triggered by engine oil pressure...the Hobbs meter records actual elapsed time while the engine is running.  On aircraft with more than one engine Hobbs may count time whenever the master power switch is on, whenever the parking prake is released or whenever a "squat" switch indicates that there is no weight on one of the main landing gear struts.

 

I'm only guessing, but I think our hour meters record actual elapsed time with the engine running...it may be key-on time rather than runnung time, but those two will be too close to call most of the time.

does anyone know if this hour meter is capable of performing the same as the F150's where it can display battery voltage, tachometer, etc?
