Overview

Important Notes:

The PRL Motorsports aluminum Coolant Expansion Overflow Tank replaces the unattractive, factory plastic tank with this sleek and sturdy aluminum tank that better fits the aesthetics underneath the hood of your car. The internal volume of our Coolant Expansion Tank is equivalent to the factory tank, resulting in no coolant loss.

Our expansion tank is constructed of TIG-welded, 3mm thick aluminum and anodized gloss black durability. Each tank includes a billet aluminum cap, sight glass and custom lower fitting to fit the factory coolant line. This kit requires no modification for installation and reuses all factory hardware.

Over time, heat cycles and age can cause plastic coolant tanks to fail. Fortunately, our aluminum replacement improves heat-transfer due to its superior thermal conduction properties, and resists high coolant pressures commonly associated with race engines!

Technical Notes:

  • (1) 1-Piece Aluminum Tank (Anodized) w/ Integrated Mounting Bracket
  • (1) Adapter Fitting
  • (1) Billet Overflow Cap
  • (1) Sight Glass

Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

The factory part was on backorder for weeks, so this was a perfect direct replacement that fit my 2023 Integra exactly. The plastic feels identical in thickness to the OEM one I removed, and the level markings are crisp and easy to read.

Charlotte ★★★★★

The tank has a nice, sturdy feel to it and the hose connections were snug right out of the box. Was worried about the fit on my RHD Integra, but it dropped in without any issues.

Amelia T. ★★★★★

The fitment list is spot on — I double-checked my 2.0L and it bolted right up without any fiddling, and the plastic feels sturdy enough to survive a few heat cycles. Shipping took a couple days longer than I hoped, but the tank itself looks identical to the factory part.
