    Need to buy an oil pressure sender switch socket to remove the sender from my 89 Caravan w/ 2.5 engine. There are two size sockets available. One is 1 1/16; the other is 1 3/16.

    Anyone know which one to use?


    Thanks for the help!

    Merry Christmas!

    Depends on who supplied your sender. Can be either.

    I have found that the OEM switch socket is 1 1/16".

    Thanks so much! I had a deep socket, but have not been able to find it. This saves a LOT of time. Thanks, IC!!

    Well, I have purchased a 1 1/16 and 1 3/16 inch socket (s) and none of them work! Not deep enough. Using the Standard oil pressure switch. Anyone use the correct socket for removing the switch? Lisle and others make one. But it's pricey! Cannot remember what I paid for the one I can't find! Can't remember the brand or where I bought it. HELP Appreciated.

    Happy 2018!

    As i recall, the switch is designed in a way that a normal socket does not fit it. I believe you need the oil sender socket.

    it's on the front of the block, accessible, so I used a large crescent wrench. Worked fine.

    I agree, a crescent wrench works because of the flat spots on the sender, but a regular socket may not because the corners don’t make a perfect hexagon.

    I've used a pair of channel lock pliers from time to time over the past 45 years of tinkering with cars.

    Go to the parts store. Ask for the sending unit. Then find a socket that fits the new one. If yours is leaking then you need a switch anyways.

    Works if you get a six point socket. Hard to find one with enough depth to clear top. Crow's foot works fine.

    The OEM hexagonal oil pressure switch/sender has the 'rounded' points that a standard 6-point socket tool won't fit onto.
    A special socket is made for these switches/senders:
