Help with oil pressure sending unit
 

I have a 2002 Olds Alero with 3.4 engine. I need to change the oil pressure sending unit. I see it's located next to the oil filter and shouldn't be much of a problem. Can someone tell me the best way to remove the old sensor? Should I use a socket and if so what size is it or can I use an open end wrench and just remove the oil filter?

I used an open end wrench and removed the oil filter for more clearance only because I did not have the right size socket. A socket is easier if you have one that fits.

its a real big size. im wanting to say 13/16 or something. i didnt have a socket big enough. you can remove it without taking off the oil filter but it takes alot of wrench flippin

I think the one on my Bonneville is 1-1/8".

Theres a specific socket that has to be used. ull have to ask the parts store if they carry it but theyre not hard to take out. jus a little hard to get to in some case. i had to take my tire off and the fender well to be able to get to the unit.

and theres no reason to take ur oil filter out and have oil going everywhere... try taking the tire off first.

i have a 98 boneville and its an 11/16 .. i literally just changed it a week ago

i hv an app that i can look up the part and the specifications on it.. what make and model is it? i can tell u what size socket ull need

YOUR PART INFORMATION 2002 OLDS ALERO Sending Unit
 

this is at auto zone . i bet u anything its an 11/16 but it has weird notches in the socket to fit the shape or ur unit. call auto zone n give them the part number for which unit u want and ask them about the socket. they carry them.
