Review on Mishimoto MMRT-CAWRD Aluminum Coolant Reservoir Tank in Red - Compatible with Various Models by Caleb Quade

I replaced my stock Mazda spill tank with this due to lack of space and am very pleased. 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.
