Add some reliability and engine bay styling to your Focus RS/ST with the Mishimoto RS/ST expansion tank. This tank features internal baffles to prevent coolant starvation from overflow ports on the engine. Also, during high speed cornering, braking, and acceleration, the internal baffles reduce coolant sloshing. The engineers at Mishimoto have included a sight tube to allow for proper observation of hot and cold coolant levels, making engine maintenance much easier.Eventually, you'll have to consider the health of your plastic expansion tank. Plastic is prone to failure after years of constant temperature variations. The Mishimoto tank is constructed from durable, TIG-welded aluminum for optimal durability and longevity. It reuses the stock expansion tank cap and includes an overflow nipple on the fill neck for adding an additional coolant tank so your Focus RS stays NHRA legal. All areas of concern are covered with this upgrade. It's worth noting the Focus's stock tank is an engine bay eye sore, whereas the Mishimoto tank comes in three different variants to help with aesthetic customization: black, wrinkle red, or Wrinkle Nitrous Blue. Each of these options works with both the 2013-2018 Focus ST and the new 2016-2018 Focus RS. For convenience, you can install your new coolant tank upgrade in under one hour as it was engineered with perfect fitment in mind. Like all our Focus RS parts, this expansion tank also includes the Mishimoto Lifetime Warranty.

Perfect EXCEPT for the Noise
Size: 30mm, Color: Pink/Rose Gold-Tone/Cream/30mm, Size: 30mm, Color: Pink/Rose Gold-Tone/Cream/30mm
My ideals for a watch are: full numerals, easy to read (good contrast and numbers, lines for the minutes and hours), light up function, case under 33mm, swappable bands, and preferably cute, in either silver color or rose gold color. This one checks all the boxes... And is the only one I've found which does. You can see on the picture that I replaced the band. Now here's the problem... The watch is LOUD! The analog watch I'm replacing is entirely quiet except when brought to the ear. This one... I hear it from feet away. My husband hears it from feet away too. I've tried two of the same model and they're equally loud. It gets distracting for me. Not at night, as the blankets mute it up, but during the day. Holding my phone typing this up, or during work, conversations... even when driving I hear it over the engine and traffic noise, because the driving position brings it closer to me, tick tick tick tick. It's impressive how that sound can carry. I've read on the internet a few people saying they improved the noise of their Timex watches by removing the hand that does the seconds. I love having it but I might just get desperate enough to try this little operation. This is the perfect watch for me except for that problem. So sad. (EDIT: I did end up trying to remove the seconds hand. It did quiet down the watch. Unfortunately, I also broke the watch in the process of putting it back together. I've decided to cut my losses and I'm now wearing a Fossil Carlie Mini (roughly $100, and available on Amazon, entirely quiet). Doesn't light up or have full numerals but what can you do. I wear a cheap digital that can light up at night and make do.)

Love it
Size: 30mm, Color: Pink/Rose Gold-Tone/Cream/30mm, Size: 30mm, Color: Pink/Rose Gold-Tone/Cream/30mm
This is a great simple watch. It fits my wrist well and is very comfortable. I really like the champagne/pink band along with the rose gold face. I didn’t realize if you push the button on the side of the face that it lights up for easy reading in the dark. Nice detail! Feels like really good quality! I hope it lasts me a long time.

Beautiful and reliable!
Size: 30mm, Color: Pink/Rose Gold-Tone/Cream/30mm
I just love it. It is beautiful, comfortable and I love the back light! I tried two or three smart watches that were reasonably priced and none of them worked well. I did not want to spend several hundred dollars for a watch. I finally decided on a good reliable watch and chose time mix. I’m really glad I did.
