Answer 2

The oil pressure sending unit is a small roundish device that screws into the block of your engine very close to where the oil filter is attached. It's approximately 1 1/2 inch in diameter and will appear to be made of plastic which most predominantly are. Attached to the sending unit will be a wire with two conductors. The wire is attached to the sending unit via a clip so that it can be pulled gently off, the sending unit removed with the correct sized socket and replaced with a new one in reverse order. Be gentle with this as it really is made of plastic bonded to metal. Clean block surface and apply a thin coat of oil to the block contact surface of the sending unit (just as you would when putting on a new oil filter) as this assures a leak-proof seal. Do all this while the engine is cold and turned off so that you don't burn yourself or get oil all over the place. This is an easy and inexpensive driveway fix but as always, since you will be under the vehicle, its wise to chock your tires and engage the parking brake so you don't accidentally run yourself over.

Answer 3

Some require a special socket to R&R and others you can use regular deep sockets or wrenches. Also, most use a tapered pipe thread that requires thread sealant applied to the threads. If the unit uses a tapered pipe thread, do not over tighten the unit. So be gentle!

Answer 4

It unscrews. There is a socket made just for that. Probably around $4.
