Installed in Chevy Silverado. Replaced the pump at the same time just in case the old one was worn out. I think I saw a utube video on how to replace it the reservoir and pump. I've had no issues since installing it. The old owner of my car put water in the reservoir and it cracked when it froze. Was a direct fit but took and little shifting to align the bolts.

It was simple to install just a tight fit. That was the fault of GM not the part. Took several hours to install. It fit and functions well. Saved me money in the long run.

Replacing the original which had a split in it, this bolted in perfectly and had no leaks. The only difference between the original and this on was the fact this one was made in China and the cap was kinda flimsy. I replaced it with the original cap.

Delivered earlier than promised. When I went to install it I found out it wasn’t the problem. One of the tubes had split. So I returned it and was promptly refunded the cost. I love Amazon.

This product works like it should. I haven't had any issues with the plastic. It's been installed for over a month now and no cracks or any defects. Filled it full with washer fluid. Installed on a 2005 Chevrolet 1500.

Fits fine except the mounting tab on the top is angled upward at about a 60 degree angle instead of being horizontal like the factory original. A previous review stated the same concern. I don’t know why the manufacturer doesn’t correct this design flaw. Just like a previous reviewer, I used a heat gun to gently heat and reshape the tab so it wouldn’t be in the way when reinstalling the battery tray. I’m not sure you could install the reservoir without this modification unless you cut the tab off which I definitely would NOT recommend. I would have given a five star rating if the top tab wasn’t a problem and I didn’t need to heat and bend it into the proper position.
