Engine/Transmission (1994 - 1998) Oil pressure switch on 95

[KOG]

Just replaced one today and what at PITA! There must be a special tool for this. I have the correct socket for the sending unit, but it can't be used until the PS pump is moved. Finally figured out after I was done that if I'd put a 45 degree street ell in the block I could have gotten the socket on the sending unit with no problem.

15/16" wrench?

Or whatever the right size is. .

Yeah even with the correct size wrench, you don't get much room to tighten it up. It's a slow tedious process. I did mine late last year.

 

[KOG]

It's a 1-1/16. That's not the problem. You can't get an open end on it because of a depression in the block where it sits. And it's too close to the PS pump to get a socket on it.

Just a thought for future referance and if the sender is not leaking. It might be easier to find a different pressure source and install the sender there.

I think that is a great idea, maybe a 90 so it points straight down. The '98s have a fitting between the block and the sender that makes the job easier but I wish I had thought of the 90 when I had the engine out.

 

[Cosmo]

Maybe that's why I don't remember it looking like that big of deal.

I swapped one out in a parts store parking lot, hundreds of miles from home, with a pair of Channellocks. I wouldn't usually consider Channellocks special tools but it was pretty easy on my '97.

Is there enough engine vibration to eventually break a 90 degree fitting?

Bill

I don't think so. The straight fitting I have now is one I stole from a '98 block about 170k ago. The sensor is pretty light.

Could a tubing wrench be used? Or a deep of-set wrench, how about a go-through socket retachet? Havent done one so just asking questions that intered my mind.
