Description
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!

Was absolutely worth getting for the level tube alone. It came a long way from Grand Junction to North Wales. Thanks guys I love it 😁
Solves a potential issue and looks cool
No more fear of the coolant tank being a ticking time bomb. Would like to call out Moroso has the inlet and outlet in standard sizing instead of metric. The return line on top is slightly smaller, by 0.5mm, but you can reuse the original spring tension clamps if they’re in good shape. Otherwise replace with new ones. The outlet at the bottom is bigger by ~2mm, so if you’re having trouble reusing the original clamps, might want to look for a 24mm alternative as the OE is measured at 22mm. I would avoid generic worm gear clamps because they don’t provide for the hose to expand and contract. Alternatively, if spring tension hose clamps aren’t your thing, the. perhaps find constant tension worm gear hose clamps. Definitely pricey so do keep that in mind.
It took me about an hour to install, but installing the factory cap and bottom hose were a PITA and the rest was easy. Watch out not to drop any of the bolts in the bay as I did as it can be hard to fish out.
That said, this was installed prior to my first SCCA Track Night event. As my daily driver NC1 it has been 8 months, 3 Track Nights, and 3 autocross events and the coolant tank has not skipped a beat. Everything seems solid and reliable with it. No complaints other install, but it could may vary with other NCs.
Only took about an hour, and one scraped knuckle. Except for the part when I dropped my pliers into the engine bay — took 3 of us to retrieve them.
Looks great and no worries about coolant tank failure.
