Review on Mishimoto MMRT-CAWBK Coolant Reservoir Tank - Aluminum, Black Compatible by Josh Allen

I replaced my standard Mazda spill can with this due to lack of space and am very satisfied. It's good build quality without all the bullshit. You just have to make sure that this bottle is at a higher liquid level than the fill hole. Also note that this is an airtight vessel, so steam cannot escape. It does not come with a pressure sensitive cap. I just tapped it with the bleed valve.
