No owners manual 2005 chevy equinox...

Did you check your owners manual? If you do not have it check online to see if you can find one.

Symbol for a "Check engine" light. If vehicle is 1996 or newer, you will need a OBDII scan tool to access the computer for codes.

Alternatively, you can go to a National auto parts store such as "Autozone" and they will access it for free and tell you the code(s).

Using the codes for that vehicle, you can identify the problem area. Most common are O2 sensor codes, usually meaning to replace the O2 sensor.

Knowing the code, you can access the internet for more information on the code and particular vehicle.

their is a wrench next to the oil light and the engine light stays on what is the problem with the equinox it is a 2005

That means its time for an oil change, possible it was'nt reset at the last oil change

I know of no such warning light on the 2006 Chevy Equinox that shows a wrench with an engine. The wrench with an oil can beside it means that there is scheduled maintenance required as listed in your owner's manual. You will see this when it it time to change the oil. The light that shows an engine is the Check Engine light and comes on when there is a problem with the emissions system. It requires that the ECU be scanned with a scan tool to retrieve the code that has been set. A trained professional will use this code to repair the problem.

I believe that would be your "maintenance due" light. Most GM vehicles as of 2005 or so have a program built in to the vehicles computer that will let you know when it is time for your normal service to be performed. It measures this by how many times the vehicle is started, how long it is run for, etc. Sometimes it will come on after 3000 miles, sometimes 5000 miles and sometimes more. GM says that once the light comes on, they recommend you have an oil and filter change and any other necessary work done within 500 miles of the light illuminating. On average the light will come on about every 5000 miles but it can go to 8000 miles. I would suggest no matter what that the oil and filter be changed every 8000 miles at most with regular and not synthetic oil. You can always do the service sooner than that. Transaxles should be serviced at 30,000 miles or less on front and all wheel drive models on the Equinox. Please rate me on this answer.

5W30 it is printed on the oil fill cap

Hi to reset the oil life monitor
turn the key on engine off
push the gas pedal to the floor 3 TIMES WITH IN 5 SECONDS
the light will flash then go out

If the service light is on in your TrailBlazer, open the door, turn the key to ignition position and push the accelerator pedal 5 times, the service light will flash. flash your high beams and you're done.

Well if it s like most the chevy cars trucks turn the key on and depress the gas peddal 3 times within 5 secounds and it should reset if not look in youre owners manual
