The knock sensor is located about 6" behind the oil filter, mounted on the engine block.

To see it is nearly impossible, there is not clear line of sight, but I placed my laptop on the engine and and I dropped the webcam behind the engine. I attached the webcam to a wooden stick so I can turn it. I also dropped a work light behind the engine as well. Replacing it is another story. I had the car on a ramp and worked from beneath. You can't see it and worked by feeling it, and you can not use both hands, there is no room. I had to cut a open wrench (if you don't have a stubby), I believe is a 12mm. I all honesty I gave up installing it, but I ultimately appealed to God for help, right there, under the car. To thread the bolt through the knock sensor, holding it right, placing it over the threaded hole in a very crammed space and turning the bolt, mostly using your index finger because there is no room for the thumb, using only your right hand and not seeing what you do IS A MIRACLE.

Note. After I removed the old one I pulled it up (the wire harness is long enough and allows) to the top of the engine where i could disconnect the old and attach the new. Good luck. (unfortunately I deleted the snapshots I took with the webcam...)

For G20 engines-SR20DE- Go on E-bay and there are several companies that will ship you an engine with about 50,000 miles for $500 or less. Your labor costs to put it in depends on how much your mechanic charges you to install the engine.

how do you disarm anti-theft in a infiniti g20

1993.5 Infinity G20 alarm removal / disengage /disconnect. Pulling the wiring connection off of the theft module cured my problem, who needs an alarm on a 1993 car anyway? The alarm mode was on with dead key FOBS and no way to reset it, horn beeping, would not start, and the alarm would not turn off with the key or remote.

1. disconnect battery

2. disconnect theft module, the theft module (black box the size of a pack of cigs) is located next to and right of the steering column next to the flasher module (turn flashers on and you can feel the flasher module pulse). It is tucked up under, but the push tab can be reached as you pull the connection out, I took the steering column cowling off and the metal dash shield so I could get at it better (a few screws and bolts., no big deal)

3. assemble dash

4. connect battery

I've been battling with this myself. I even have the same year as you. Last time I changed the fluid I special ordered the Type-J that the owner's manual calls for. Now I am replacing my tranny and my dad being in the auto parts biz most of his life got me Dextron III cause his books says that's what it callse for. He swears that it will be allright. If he is wrong then I'm going to make him buy me a new tranny. I guess I have heard from a few different sources that Dextron III is OK, so. I've been battling with this myself.

warped flywheel and/or bad clutch

We are having that problem with our 1999 G20t. My honey first had the alternator and battery checked (he removed them ad took them to Advanced Auto). Those were in great shape. We were told it could be the ignition starter switch or starter fuse. Those two parts are only available at the dealership and not too expensive if you can replace it yourself. We are looking fro pictures on the net that might show us were those are located in the car. Hope that works a little.

It is quite easy actually! First off you need to loosen the tension bracket from the top, it's a longer bolt slightly above the alternator, now you need to get under the vehicle, there are only really two bolts holding it on, one very long one and a shorter one. After those are removed you can unplug the alternator from its power source on top...now to remove it..a little tricky! You now have to remove the A/C motor which prevents you from pulling the alternator out from the bottom..it is held on with 4 bolts..once it is off you can drop the alternator..

I don't actually follow the second part of the above answer because removing an an a/c motor is not quite easy. I removed the alternator from the top by removing the big radiator hose and its housing unit from the engine. When you put the housing back, just make sure you seal it good so water won't leak.

I have recently been researching the same question and the consensus is that the headlight switch needs to be replaced. Several people have said this solved their problem.

do you have avideo

all i know is that most functions of the shifter are actuated by the brake pedal and until the brake is applied the shifter will not move

<<take a wrench and crawl under the car, there should be a few colored wires next to right front wheel. take the red wire and cut it close to its starting point, the alarm will start. then cut the blue and yellow wires immediately afterwards

That is a crap answer...

In the fuel tank

NOt sure 100% how we did it. Me and my neighbor took it all apart, and had a problem getting the axles out. Then, in a stroke of brilliance, I figured out that the reason we couldn't get the axle out is the fact that Park is a gear. When you are ready and have most everything taken apart and are ready to pull the axle, put it in nuetral. Neutral isn't a gear and they will slide right out. Hope this helps!

The 1995 Infinity alternator can be replaced by removing the alternator belt. Removing the wiring harness from the back of the alternator. Removing the alternator retaining bolts. Put the new alternator on and reverse the process.
