Renew the coolant every 24,000 miles or 2 years which ever comes first.
If your battery is in good condition, there is no need to change it.

04 Trailblazer oil percent at 23 percent. I changed the oil and reset it now it's says 100 percent, I turn off vehicle and turn back on and it says 23 percent again and again.


Just a Gadget-forget about it,
don't need it

You change your oil when you want to

I would suggest every 4,500 miles

3 or 4 times a year

Nothing there tied to the vehicle oil

How do I reset the PCM on a 04 chevy trailblazer


I disconnected the battery, removed fuses 10 and 28 adjacent the battery and waited twenty minutes. I then hooked the battery back up reinstalled the fuses and started the vehicle. The battery light went out and the battery not charging message did not come back on. I then went for a test drive. I had a celebratory adult beverage because it worked.

How to reset the oil change button


I have a 2004 Chevy Silverado. With the vehicle in neutral look on the right side of your dash you will see a black round button press the button until you get to the prompt for oil and mileage. Press the button it will clear it back to 0 again.

I hope this helps you out if so please leave me some feedback.
