It could be your oil pressure sending unit is sending a steady signal because its defective. If it is, they are very simple to replace.

SOURCE: oil pressure on a 2004 5.3 liter silverado at idle is around 20

The pressure to be most concerned with is the reading in gear at idle with engine warmed up...Low end really should not be below 20. If pressure wanders, change the sending unit and check actual pressure with a mechanical gauge if necessary. The age and quality of your oil, as well as temperature all play a part in pressure, as well as internal wear from time & miles of use. If pressure changes with rpm, that is normal. 40psi is good while driving.
need more info just ask.

You probably need a oil pressure sending unit it is located at the back of the engine and is a high failure

My 2003 silverado is running 80 lbs.oil preasure what should i do


need to hook a oil pressure gauge (tool) to it to actually see if it is running that high. if it is then if its a high mileage engine put a can of sea foam in the engine oil and run for 500-1000 miles. then change it and see where it gets you. pressure is resistance to flow. the only thing to cause it to get that high is tight oil clearances or a restricition in engine. this is a cheap try it solution. if the tool does not read that high replace the oil sending unit.

I take it the guage was fine untill you changed the battery? There a special policy on clusters for 03 and 04 gm ck trucks 7 years and 70k covered 100% Between 70 and 80 k warr will pay for the cluster and you pay labor.The guage needles have a problem of sticking.Call your dealer and ck with them about the special policy 1st.I hope you truck falls with in the guide lines for warr.

Trying to find out how much oil the Triton V-10 takes when I do my oil change? I cant seem to find it or anyone who knows


It should be listed in the owners manual, but because of different oil cooler setups you may have to do the change yourself and add oil until the correct level is established..... for the first oil change.
Most likely 7 liters,but start with 5,run the engine to fill the oil filter,let it sit for 5 mins and recheck and fill to full.
Note the amount needed for next time.
