NC Aluminum Coolant Expansion Tank

Thank you. You have rated this product.

Direct replacement for your factory plastic coolant expansion tank. Made in the USA, all aluminum with beatiful TIG welding. Constructed with internal baffles and a machined aluminum neck that takes a factory cap. All of the inlets and outlets are positioned to match up with the factory hoses. The tank mounts to the same location as the factory tank and is built with the same dimensions for an easy fit.

As these cars age, the factory plastic tank is a common failure point because the plastic gets brittle and cracks. Unlike the earlier cars where that just meant a leak, the NC relies on this tank to be a pressurized part of the cooling system, which means that as soon as a crack forms the system loses pressure and the engine overheats. We've had more and more people bring in cars with blown motors due to this simple failure, and along with a new expansion tank now they need a new motor as well, so we decided it was time for a "lifetime" solution. This tank is the solution. It will not fail over time like the factory tank, and looks great as well!

Install Tips. If the tank is old and cracked, likely the hoses are old and cracked too, good idea to update both at the same time for best results. Track customers may want to upgrade to screw clamps instead of the old stock host clamps. #4 worm clamp (x2) for the top two nipples, #10 worm clamp (x1) for the bottom.

Great write-up of the install over on the Revlimiter blog:

REVIEWS

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
