Greetings to all my fellow chevy owners. I have a 1999 Silverado LS, 5.3L. This is my first post here so please steer me to the right page for my problem. Short story, I took out my gauge cluster to clean it and replace the stock bulbs with blue led lights. I'm embarrassed to admit that I removed the needles for all the gauges without marking their position. I have put the needles back to where I "thought" they should be but of course after 3 tries of starting, then off, and pulling the needle up and moving it a little, then repeat the process. Even if I get the rpm and speedometer set correctly I can't be sure about the other gauges. Sooooo, I was hoping there is some magical combination of tasks to do to get a factory reset or something that will calibrate the gauges for me. your help is much appreciated.

 

Do you have and OBDII code reader/live data scanner that you can use to monitor engine temperature, engine RPMs and volts? Those three can be set by monitoring the live data stream. While the engine is running,you could set the oil pressure indicator to the middle position, and for fuel, the next time you fill up, remove the instrument panel and set the needle to the full mark.

Unfortunately, I do no believe that there are live data streams or sensors that report either the oil pressure or the level of fuel in the fuel tank which can be read via the OBDII port.

If you do not have access to an OBDII code reader/live data scanner, and you have an Android device, I would suggest you spend about $25 and get this Bluetooth OBDII dongle and the Torque Pro app from the play store. It will read and display just about everything you will ever need to know about your engine and emission system.


Good Luck!

 

Thanks for the tip. OBDII to be delivered today, got Torque Pro installed, waiting on delivery.

 

Good Luck! By the way, my oil pressure at idle is about 55 psi.

 

A/C died so I dropped my truck off to replace compressor, evaporator, fan, and belt. Ouch! 2k. I'll hook up the OBDII this afternoon and post my results.

 

Ouch! I how that hurts.

 

ouch is right! Think you need to find a new shop! As for the gauges, you're on the right path, obd2 to the rescue
