I am looking to replace my oil pressure switch on my car listed above and I have not been able to find a video or a procedure on how to do it. If someone could help me out that would be great.
Do you
have the same problem?

Can you find the location?

Here is what the switch looks like:

http://shop.advanceautoparts.com/p/carquest-by-bwd-oil-pressure-switch-s4363/10433389-P?searchTerm=oil+pressure+switch+socket

Some people pull them out with channel-lock pliers, you risk "egging" it and messing up its operation.

A regular socket will not fit it.

This is what you should use, it fits perfectly. Some of these are "stepped", the step will fit other sensors with the same design but have a different diameter. (useful on other repairs)

The particular brand of sensor (first link) already has sealant on its threads.

No need to drain the oil, you may lose a little bit of oil (insignificant) when you take the old one out. (just so you might stick a rag under it to keep the driveway clean)

Start the new one in, insure it goes easy and is not cross threaded.

Tighten it good and snug. Do not get down on it with all your might.

Crank it up, get to operating temperature, look for drips or a leak, if it does, go a bit tighter.

easier to snug more if needed, than to get a broken sensor out of the engine.

This like changing the spark plug in your lawn mower/ weed eater!

Looks Good?

Hook the wire back on it.

Stick you with a fork, you are done!

Return with good news!

No, I have no clue where it is. I thought that it was on back side of block which is under the fuel rail which seems like a pain to get to then I thought someone said that you can acces it by taking the battery out and the battery tray. That is why I was looking for to be told what the whole removal process is. Lol

Right side of the block, near the oil filter.

I was able to obtain you a component location diagram from "Prodemand".

This should be a really easy repair.

Post us as to your progress,

May the force be with you!

Does it fit the new one snugly?

You do have an oil light not an oil gauge?

The tool is stepped for 2 different sizes, could it be you are on the bigger step and need to be on the smaller?

Reckon the old one was installed with pliers and they "egged" it? Now it won't slide into the socket?

The new one that I bought fits in there but it seems to have to go deep in there to fit it I bought the exact one you showed me at advanced I didn't know how it could be two sizes considering the ratchet end only fits in one side the of the pressure socket?

This ain't your particular socket but similar

Got pic below off of the net, it was clear to see

Notice the 2 sizes at the open end of the socket (like a step), the socket will fit 2 different sensors.

I thought the one I suggested (I looked it up on their site) was the same as it said it would fit 1" and 1-1/16 (if either is the size of your sender)
