Oil Pressure Relief Valve Location, 96 Bonneville SE?


1996 Bonneville 3800

Can anyone tell me how to access this valve and spring?


Thanks

Jim

It'* on the passenger side of the motor. You need to pull off the oil filter adapter. It'* located behind it in the block.

Thank for your response.

Is the best way to get at the oil filter adapter through the passenger wheel well?

Just in case there is any crud in the adapter or the relief valve bore what is recommended to use and method to clean them up? Brake cleaner, parts cleaner?? Can these solvents damage anything in this area.

Thanks again.

Best way to get at it will be through the passengerside wheel well. Jack and remove the tire. Remove the splash shield and it'll be right there.

It'* held on with 4 13mm bolts. They are a pain in the neck to get at with the axle in place. Pull the oil pressure sender out first. Using channel locks and only squeezing the metal, not plastic body of the sensor.

If you are thinking about doing a transmission service (drop pan, change filter, refill) then I'd do it at the same time and pull the axle. Doing so gives you all the room you'd ever need/want. It'* possible to do it with the axle in though.

I found using a razor blade in small vice grips or a small scraper worked well. Then spray a cloth with brake cleaner and wipe, don't spray anything directly into the area with it open.

Bill.

Thank you for your quick reply.
Your information is detailed and very helpful. I'm doing just the oil pressure relief valve.
