On your intake manifold, #3 in diagram. My info showed two wires, one is gray, the other is orange with black tracer.

You must scan the system with a code reader.

to the left of the oil filter.

If you pop the hood and look at the engine, if it says Ecotec, you have a canister/cartridge filter. It's located below the intake manifold. To get it out, loosen the 36mm head of top of the filter housing.

Your oil filter is located on the right side underneet the power steering oil. Its a black cap with a square notch on it to remove it.

Hope helps (remember to rate and comment this).

Have the alternator checked.

ECOTec 2.4 Liter engine (and all ECOTec engine blocks in 4 cylinder sizes) have a cartridge type oil filter housing on the front of the block, driver's side of the vehicle.

The cap must be removed with a wrench, and the filter pulled out, then the new one put in. Now is usually a good time to replace the O-ring on the cap.

There are several engines that will fit the 2.2l Ecotec, 2.4L high out put motor, and I have actually seen a chevy cavalier that has a 3800 V6 in it if you want to go all out but in most cases sticking with the ecotec motor or the 2.4 High Out Put motor would be best they are two of the best motors for these cars and since the Sunfire is basically the same car as the cavalier almost any thing motor wise is inner change able between cars depending on the motors i own an 2004 chevy cavalier LS sport and a buddy of myn has a 2004 Pontiac Sunfire and both have the 2.2L Ecotec and are both Manual trans and even most of the interior parts are the same except for some of the dash board components hope this helps you out
