I need the location of the harmonic balancer on my 2.2l Ecotec engine. Car is 2004 Chevrolet Cavalier LS.

From the internet search. This is on the back side of the engine. Crankshaft position sensor is near the oil filter. Camshaft position sensor is straight above.

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

well if you try to restart the car yes it does but if that happend in once with no any try to start the engine so your engine is ok and ready to run agian after reinstalling a new chain

crank is on the side of the engine just above the sump pan by about an inch or so. right side.

how old is your battery? that might be it also.

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.

Hello cmalstrom.

The sensor is mounted to the right of the harmonic balancer at the front of the engine.
On the diagram below look to the left about 3/4 of the way down.
I apologize for the size, we are limited here for amount of room.
If you need more help with this please ask me.
Thank you for using FixYa.

The crankshaft position sensor should be located on a small metal bracket very close to the harmonic balancer which is attached to the end of the crankshaft. If you are having trouble locating the harmonic balancer, it is the lowest pulley on the passenger side of the engine, in the center line of the engine.

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
