Moroso aluminum coolant expansion tank for NC

Moroso aluminum coolant expansion tank for NC
Moroso aluminum coolant expansion tank for NC
Bombproof your cooling system and potentially save your engine.

Made in the USA

Exclusive to Flyin' Miata

Availability: In stock



The "overflow" tank on your NC is actually pressurized and part of the cooling system. The oldest ones are now over a decade old, which is asking a lot for a plastic box that's a critical part and exposed to high heat levels. We've seen a few damaged engines from cracks in the stock tank, leading to a loss of pressure in the system and overheating. This aluminum part will solve that problem and give your NC the protection it needs.

Plus it looks awesome.

Bolt-in replacement for stock. Includes a sight tube so you can check coolant level. Fits all NC models. Exclusive to FM!

Great product
Excellent tank, very high quality. It looks great and feels very substantial. Install was a breeze. I dribbled out a little fluid, not much. If I had 3 arms or a couple corks I wouldn't have lost any.

Great Product & Great Customer Service
This is a two part review.

First, a review of the coolant tank: It’s very obviously well made and it installs very easily. The site glass is an excellent, much needed touch. Be aware, since it’s a solid aluminum tank, it will be the same temperature as your coolant at any given time, which means it will be VERY hot after the car has reached operating temperature.
Second, a review of Flyin’ Miata’s customer service: When I first installed the tank I noticed that the lower fitting for the site tube was leaking. (I still rate it a 5-star product...anyone can get a bad fitting here and there) I immediately started the return/exchange process per FM’s easy to follow instructions on the site. Once the process was started, Mike gave me regular updates from start to finish, and he served as mediator between me and Moroso. (They we’re also easy to work with) He assisted me with the entire return process and then checked to make sure everything was up to par after I received the tank once the fitting was changed. I always hate having to do a return or exchange, but FM and Moroso made as painless as possible. Thank guys!

Great product!
Install was super easy. While doing a coolant flush and fill, I unbolted the tank and removed all the spring clamps with my fingers. Replaced with worm clamps, remount and done.

Noticed those baffles inside too, nice to know its similar to stock design. Sight tube is a handy touch. Thank you for a quality replacement tank.
