I bought a used vehicle from a recent widow (mother of my neighbor).
An ‘05 Chevy Trailblazer with about 140k on it. Garage kept and very nice shape for the year.
When I bought it, I knew that the oil pressure gauge fluctuated when the engine was warm and you came to a complete stop. It would drop to zero, bounce back up to 40, drop halfway down, drop all the way down, then bounce back up to 40, etc. i’ve been down that road before, and figured it was the oil pressure sending unit. I took a gamble.
I ordered the sending unit, and the special socket tool, off Amazon. It came in a couple of days ago. I decided to replace the sending unit and do an oil-change at the same time. Sticker on the inside of the window indicated it was about time so I thought I’d knock it all at the same time.
Within five minutes of getting the vehicle up on ramps, I had the sending unit replaced.
Drained the oil. Now I’m only 10 minutes into the job, and ready to remove the filter. Four different oil filter wrenches, a vice grip chain type included, and I have yet to budge the filter after 45 minutes of grunting, cursing, and contorting! The only reason I didn’t just break down and drive a screwdriver through it is because there wasn’t any room to do it!
Yes, I finally got the blasted thing off and replaced. As soon as I get finished and cleaned up, I’m thinking about taking a baseball bat to town and visiting that quickie lube place. What in the hell are these guys thinking?
Updated to add that I just took the vehicle on a 20 mile road trip, and the oil-pressure sending unit replacement seems to have done the trick.
