Need help w/ gauges!

[igbig]

I'll make this the short version. I installed white face gauge insert on my 2000 Silverado. They didnt come with instructions so i figuredi would take offf the gauge pod and do everything up to the point of removing and replacing the insert or sticker or whatever you want to call it. well i didnt know you were supposed to write down the location of the  needles before you start moving them.well guess what ? i moved them. i have no idea where they were before i jacked with them ??? now i have re-installed the gauge cluster and all of my readings are wacky! does anybody know how to re-calibrate the needles so that they are reading correctly?????

Oh man.  Sorry, I don't know what to tell you.  Someone else may be able to help though.

If you give us the motor size and rear gear ratio I know we can help you...

 

I think on all GM trucks RPM on warm idle is about 600-650.

 

Fill your gas tank up and reseset the fuel needle.

 

Your Alternator should read between 1/2 and 2/3 when the truck has been run and the battery fully charged.  Probably closer to 2/3.

 

We all know what our stock gauges read so let us know what you need...

My Oil Pressure reads 40 at idle.

As far as the speedo, this is what I would do. Install the needle resting on the black point. Drive the truck. If the needle doesn't go up as soon as you start moving forward, keep reinstalling it until it does.

leave the window of the gauge cluster off and then start the truck... the internal springs of the cluster will move the needles,  easy pry off the needles and push them on this location... but only push easy because if you push them down all the way  they will drag

 

Fuel:  try to remember what you had, or fill up and set it at F

temp: 100 cold idle

volt: 14-16 idle

mph: 0 idle

rpm: 1000-2000 idle

oil: 40-60 idle

 

if you have the tranny temp gauge just set it at the lowest setting at cold idle.

I think your RPM is a tad high.  It should be around 600rpms once its warmed up at idle.

thats all cold idle and that was the factory setting before I installed my platinum gauges

[Z71GUY]

I dont mean to get off topic here, but I've NEVER had my truck idle over 1000 rpms when cold (below 30-40 degree's).  Even when I start it in the morning with temps around 0 degree's its still around 1000 then kicks down to about 600.  Has your truck actually seen almost 2000 rpms while when at idle?

[LarryE]

no

My truck idles

 

warm - 500 rpms

cold (30 degrees and lower as of late) - 700-900rpms

[silverado3500]

Last week when it was about 10 degrees, my truck ran at 1800rpm briefly, then quickly dropped to 1200 rpm, hovered there for about 2 1/2 minutes then dropped to about 850.  

 

Then i started driving.

[Z71GUY]

Thats odd.  I wonder what makes the truck idle at 1800 rpms vs 900 rpms when cold (10 degree's or colder).  I've started mine below zero and it always idles "high" at one RPM range 900-1000rpms.  Anyone know what conditions must be present for a very high idle????
