Over time, the factory plastic coolant expansion tank on Honda/Acura models can weaken and fail from heat and pressure cycles. The PRL Coolant Expansion Tank replaces it with a robust 6061 aluminum version that resists temperature and holds higher pressure to outlast the OE tank. It more than doubles coolant capacity to 1.32 quarts (1.25 L) versus the stock 0.58 quarts (0.55 L), carrying more heat away from the engine while keeping a tidy engine bay.

Features

  • Robust 3mm 6061 aluminum construction
  • Laser cut and TIG welded
  • Internal baffling to prevent coolant sloshing and cavitation
  • Red or black anodized finish with laser-engraved logos
  • Billet-machined barb fittings and sight glass
  • Buna-N O-rings for temperature and leak resistance
