Review: This fits a 96 Buick Roadmaster LT-1 - UPDATE** Ok, I'm leaving my previous review below in case others have similar issues or already read this one. since i hadn't returned it yet and confirmed thru rockauto that this is SUPPOSED to be the right cap, I tried it again, first without putting the o-ring over the opening and just testing the cap fit. Go figure, now it decides it's going to snap shut. Don't know why these things go this way sometimes as I really didn't think I did anything different or forced it any harder. But final word, is now it fits fine. It works. I'm happy. I need a replacement washer reservoir cap for my 1996 Buick Roadmaster Wagon. Says this one fits my car. While it was easy enough to get the retaining ring on, the cap itself is a little small for the opening. It doesn't fit. Simple as that. Very annoying. Note - my reservoir tank is original, not an aftermarket. This is also the part listed as correct on rock auto. Anyone else out there that is looking for this part for their Cadillac Fleetwood 94-96, Buick Roadmaster 94-96 or Chevy Caprice 94-96 with the LT-1 engine, this isn't going to work. I'm not sure, but it probably isn't right for the other GM cars that came with this engine - firebird, camaro, corvette.
Review: Fits 2008 GMC Acadia - Although it is a VERY tight fit (so tight it almost seems like the wrong size, too small) when you first open the package and put it on, it's actually a perfect fit, snaps on and off perfectly after a few days. You have to remember the washer fluid container top will stretch and get deformed after time, so putting on a new item such as a cap, its going to fit tight or need a little shoving of the container top into the new cap. But after you put it on and time passes (about a day or 2) its a nice tight seal, you'll hear the "pop" of the cap when you open it and the "click" when closing it. Think of it like a new pair of shoes, right size but tight, you have to break them in, it's the same concept here.

### ⭐ Do not trust the specifications, they are continually wrong, and this may not fit your vehicle!
*by A***N on December 12, 2013*

This part was listed as compatible with my car. Meaning they provided this information to Amazon. When I get the thing, it doesn't fit. It would cost as much to send back as my refund would be. They're marking this as fitting cars it does not, and then a week or two later not claiming it fits that car anymore (maybe I didn't read correctly? Except I used the part finder for my car, and another reviewer also complained this part falsely asserted compatibility with models). Maybe this fits your car, but you won't really know it's true until you have it delivered. Since I can't find a cap for my 1996 Toyota Corolla, I'll just use a length of Velcro hook and loop and a piece of heavy plastic. The reservoir doesn't need refilling very often anyways.
