Radium Engineering Coolant Expansion Tank Kit – 2017-2019 Honda Civic Type-RBecause of continuous and intense heat cycling, plastic coolant tanks have a reputation of failing over time. Fortunately, the rugged 2 piece Radium Engineering replacement is CNC machined from aluminum and anodized for increased longevity. And because aluminum is a superior thermal conductor material, heat transfer is further improved. Additionally, metal construction is robust enough to use in racing applications.

Because of continuous and intense heat cycling, plastic coolant tanks have a reputation of failing over time. Fortunately, the rugged 2-piece Radium Engineering replacement is CNC machined from aluminum and anodized for increased longevity. And because aluminum is a superior thermal conductor material, heat transfer is further improved. Additionally, metal construction is robust enough to use in racing applications.

This FK8 Type-R kit directly replaces the plastic Honda tank without making permanent modifications to the vehicle. A specially designed mounting bracket secures to existing threaded holes and Radium adapter fittings interface with the factory lines. The tank functionality remains the same as the OEM cooling system.

The Radium Engineering Coolant Expansion Tank has proved itself over the years in many applications all over the world, in race and street vehicles. The internal volume of the Radium Engineering Coolant Expansion Tank is equivalent to the OEM tank resulting in no coolant loss.

The internal design features two chambers with cross-over passages at the top and bottom. The coolant tank also has an internal swirl feature aiding in deaerating the system. For more details on the coolant tank, click HERE.


The kit includes all parts necessary for installation. NOTE: The OEM 1.3 Bar Honda pressure cap can be re-used. Alternatively, various pressure reliefs of the Radium Engineering Type-A cap can be purchased HERE.


Included
-2-Piece Billet Aluminum Tank
-Aluminum Mounting Bracket

-Overflow Hose, 7/32″

Great Fit, Great Feel — A New Go-To for Workouts
Special Size: with Contrast Trim, Size: Medium, Color: Navy/White
Really impressed with this workout tank! The fit was spot-on — snug enough to stay in place during movement but not too tight. It didn’t ride up during my workout, which is always a win. The material is soft, breathable, and wicked away sweat really well during both strength training and cardio. It honestly reminds me of the higher-end athletic tanks I’ve tried — same feel, but at a much better price point. Definitely one of those pieces you’ll want in multiple colors! Pros: ✔️ Comfortable, moisture-wicking fabric ✔️ Stays put during workouts ✔️ Flattering and functional ✔️ Great quality for the price

Loose under arms, flattens you out
Special Size: with Contrast Trim, Size: Medium, Color: Black/White
I saw an influencer recommend this workout top, but was disappointed in the look and fit. It was saggy under the arms and flattened by bust in an unflattering way. This was returned.

Love these!!!
Special Size: 7" Inseam without Pockets, Size: Large, Color: Ocean Blue
Super happy with these shorts!!! Wore them on a full day at the theme park. Stayed in place and did not ride up. No pinching or constricting. The material is buttery soft and the blue is so vibrant and pretty!! Don’t show every bump and imperfection, but does show some. It’s not totally smoothing. Very work out friendly, heat friendly, running errands friendly. Would definitely recommend and plan to buy other colors. Comfy waist band as well.

Excellent Work-out & Biking Short
Special Size: 7" Inseam without Pockets, Size: Small, Color: Ocean Blue
I love these biker shorts. They have just the right amount of lycra and they are super soft. They are true to size, and they fit perfectly on my 5'2", 125-pound frame. I purchased them for use in bike riding, and I am very pleased with the fit and stretch. The inseam length is perfect for bike riding, and the legs don't ride up my thigh. The only con to all the pros is there isn't a phone pocket. I ride my bike around town, and I would have liked to have a pocket for my phone when going inside a store. These shorts are well worth the price. I purchased three different colors and love them all. I would definitely purchase this item again.
