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

Awesome small package of a coolant reservoir
Did an engine swap and could no longer use factory coolant reservoir and the tracks require an actual reservoir not just a water bottle or anything so this works perfectly. It’s not pressurized so don’t expect it to work like that just simply a reservoir.
