I have a dead battery on a 05 chev equinox. where is the battery located, i cant find it?

check your coolant levels, and your thermostat, also check that your radiator fan(s) are operating properly. check the fuses for the fans if electric.

sounds like your battery is dead try jumping it

It should be right on top of the battery on the drivers side of the engine compartment. They may be a plastic cover over it.

PCM's are the last thing I consider when diagnosing a vehicle. In the last 20 years I have replaced less than 10 PCMs or "computers" that have failed to operate as intended.

PCM replacement on your vehicle is expensive and it will need to be reprogrammed with special equipment once it is installed. Making sure this component is the true source of your problem will not only save you money but also headaches in the long run.

The Chevrolet Equinox instrument panel fuse block is located on the passenger's side of the center console, to the left of the glove box near the floor.

Hello
Possible heater core located inside cabin underdash is leaking.Or coolant hose going in or out of core is leaking.
Recommend having system pressure tested and leakchecked.

If you don't tighten the gas cap (make it click at least four times) when refueling it will turn the check engin light on. The dip stick is located in the front of the engine and is a yellow loop.

Install the NEW cylinder head bolts. Tighten the bolts as follows:

• Tighten the bolts in sequence to 44 ft. lbs. (60 Nm).
  
• Turn the bolts in sequence an additional 95 degrees.
  

I changed air bag front sensor myself $275 it's a 15 minute job and I know nothing about cars. Unplug battery, sensor is located dead center in front of hood.

there are 2 ways to do this, use a scan tool ($50 for a basic one) to reset the light, the other is to disconnect the battery for 5-10 minutes, be advised if the problem is not corrected that set the light the light will come back on in about 20 miles, also if the system is not ready u will fail smog, this means they (person doing the smog) know there was a problem.

you might have to dismantle the key ignition assembly on your steering column. Have you tried getting some channel locks or some pliers to swiftly yank out the key? Is the key bent inside the ignition? If so, you have a problem on your hands and you'll have to remove the assembly and most replace it.
