Rated 5 out of 5 by from Great Quality! The Mishimoto coolant tank is excellent quality. Even their packaging is great quality. It looks great under the hood. So much better than the milk jug looking tank that is stock on the 15 Mustang GT. I like the sight tube on the side of the tank to check coolant level. Installation is pretty straight forward and there are plenty of installation videos online. The only part of the installation video that I skipped was taking down the belly pan on the underside of the engine and partially draining the radiator. I was able to empty the stock tank without loosing any coolant all from the top side. Highly recommend.

Rated 5 out of 5 by from Great quality Seems every company is back ordered on this item. Cj pony were true to there word they had it in stock and shipped in 3 days as promised. I was highly impressed when I received the tank mishimoto takes great pride in their products and it shows in the way they package and delivered this tank. Fit is perfect and install was easy just remember to plug your hoses or you will drip coolant everywhere. Thanks cjpony.

Rated 5 out of 5 by from Clean looks - a necessary change from stock unit Quick install, looks great under the hood. Helps to siphon the coolant out first and plan to top off with some fresh... larger reservoir requires a bit more to be at the appropriate level when complete.

Rated 4 out of 5 by from Mishimoto Coolant Tank Install Pretty much like the video show; however, the bottom clamp was a pain to wrestle off. Also, the supplied bolts could use washers, there was just barely enough head contact with the tank mount. Also noticed the cap will not lock but is tight and does make contact with the hood insulation. After a drive around to check for leaks I noticed the shape of the cap molded in the insulation. This makes me wonder how long term effects on the cap.

Rated 5 out of 5 by from Great new tank We love the new coolant tank for our 2019 Roush S3 Mustang. Install was a breeze. Just follow the video instructions.

Rated 5 out of 5 by from Adds a nice touch under the hood. This main reason I bought this tank over others was the sight tube. It was very easy to install although I did have to trim the sight tube down just a bit because it had a slight bow (too long) when I pulled it out of the box. The only gripe I would have is that I wish the overflow port was a little offset to the passenger side. But other than that, Mishimoto put out a great product.

Rated 4 out of 5 by from Mishimoto expansion tank Delivery and price were great. Installation was fairly easy. The oem hose clamps are a little of a pain to remove. Probably would be easier if I had the right tool for them. The quality looks good . The tank looks 100% better than the original. I like the sight tube feature, which is my only concern reference durability, only time will tell.

Rated 5 out of 5 by from Looks great and easy install Hard item to find, CJPP finally received a shipment and I had it in hand in a few days. Looks SO much better than factory. Install is easy and simple (only spilled a little coolant :) don’t hesitate if you find it in stock, they sell out everywhere!

Does it matter how you route the overflow tube the video doesnt say and do you need to ziptie it down to secure

Asked by: Scott L
It lays in the top of the radiator.

Where exactly should the vent hose / overflow hose be ran down to? That is not really covered anywhere. Much thanks.

Asked by: aham23
It honestly does not matter, it can be ran anywhere. i would just make sure to put it somewhere where there is no chance of it interfering with any moving parts or potentially melting from contact with any extremely hot surfaces. Another key thing would be to run it somewhere accessible because if you were to go to a track event that requires an overflow bottle, you would have to install a secondary bottle and run the vent hose to it.
