Good product for a fair price.

Bought this for my neighbor’s ‘64 El Camino. Worked great. Fit just like the one that it replaced.

Works as a small windshield washer

Worked great for relocating the windshield washer fluid tank in my 2005 4runner. Look on YouTube for how to DIY videos if you’re looking to do something similar. I was worried it would be too small, but I’ve been super happy with it and I don’t have to refill as much as I thought I would.

seems quality and good value but dimensions would've been nice in the description.

i had to return it because it was too large for my application. dimensions in the description would've been nice. otherwise it's a cheap durable coolant overflow tank with universal mounting tabs so what else could you ask for? (other than dimensions)

A Good Plastic Tank

I recently purchased a 1974 Alfa Romeo Spider. The windshield wiper fluid tank had a major leak and was not repairable.This tank worked perfectly as a replacement tank and was very cost effective. Larry Hunt

Works perfectly for my '75 F250. Still going strong after a year

UPDATE 3/28/18:This reservoir has been in my truck now for over a year and is still fine. No leaks, cracks or anything.ORIGINAL:I have a 1975 F250 that needed an overflow bottle so I bought this to add to the engine bay. The bottle ended up fitting perfectly in the left side of the engine bay just below the battery and fit some holes that were already there with no drilling. The plastic is nice and thick and the cap is snug and secure. The inlet barb on the bottom was already open on mine so no need to drill. Also, contrary to what others have written, the cap on mine is vented. There is a little hole in the middle that allows the air to escape. It is a pinhole so if I wanted a closed system I could easily plug it. Glad I found this and I recommend it if you have the room.
