How do i change spark plugs on 2.4 2012 equinox

Is your security light on?? Then go to this site and read the info.. I seen that your car is one on this list. hope this helps

unscrew the clamp from the air box of the mas air flow sensor and engine on hose. remove the oil fill cap . also pull out the little vent line by the engine clamp them take thecover off and the cover under it you should see the sparck plugs

Coolant level full? Rad fan operational? Possible defective thermostat. Worse case plugged rad or head gasket

As with any no-start condition, you first need to know if it is no spark or no fuel.
You could try spraying carb cleaner or starting fluid into the air cleaner hose to check for no fuel. Or pull 2 or 3 plugs and check for spark.
Also take a look at the ECM for trouble codes.
It could be anything from a plugged fuel line to the gas tank to a bad relay to a dead ECM.

First, I think it highly unlikely that a 2011 Chevrolet Equinox would be due for spark plugs yet. They only have to be changed every 100,000 miles.

Second, you could spend the rest of your life trying to change the spark plug wires on that vehicle and never accomplish it. 2011 Chevrolet Equinox is not equipped with spark plug wires.

Then, if the spark plugs were somehow in need of replacement at this time, I highly recommend that you do not try this at home unless you have access to compressed air to clean the debris out of the spark plug tubes. Otherwise, severe engine damage can occur. (I have replaced many cylinder heads because of DIYers attempting to change their own spark plugs without the proper methods and equipment.)

With all that said, you must remove the ignition coils to get to the spark plugs.

6 Spark plugs. Sorry cant answer you second question.

The easiest way to change the back plugs on a GM V6 is to pay someone else to do it. You need good light, good tools, lots of various extensions, swivels, and universals. A good vocabulary of curse words also comes in handy.

What does your spark plug look like when you took it out? Was it black/fouled out? If so, you may have bad rings on that piston/cylinder allowing crankcase oil into your cyclinder, thus fouling out your plug.

its a real pain spend the $ and get a mechanic to do it i have one and no fun
