P2M Gen-2 Aluminum Coolant Overflow Tank – 1995–1998 Nissan S14 240SX | T6 Aluminum | Clear Anodized Silver | P2M Lifetime Warranty

Replace the factory plastic coolant overflow tank on your 1995–1998 Nissan S14 240SX with the P2M Gen-2 Aluminum Coolant Overflow Tank — a redesigned, high-grade aluminum replacement that addresses the known failure points of both the OEM plastic tank and the original P2M Gen-1 design. The factory S14 overflow tank uses an exterior plastic sight tube to indicate coolant level — a tube that dulls, cracks, and leaks over time, eventually making coolant level monitoring unreliable or impossible. The P2M Gen-2 eliminates this failure point entirely with a cleaner, more reliable design built from T6 aluminum with a clear anodized silver finish.

Gen-2 Redesign – Key Improvements Over Gen-1 & OEM

• Exterior Sight Tube Eliminated: The OEM and Gen-1 exterior plastic viewing tube dulls over time from heat and UV exposure, making coolant level difficult to read. It also cracks and leaks — a common failure point on aged S14 cooling systems. The Gen-2 design removes the exterior sight tube entirely, eliminating this failure mode
• Integrated Dipstick Viewing Tube on Threaded Aluminum Cap: Coolant level is now checked via an integrated dipstick built into the threaded aluminum screw-on cap — a more reliable and durable solution than the exterior sight tube. Clean, simple, and not subject to the dulling, cracking, or leaking that affects the OEM sight tube design
• Improved Threaded Aluminum Cap: The screw-on cap is machined aluminum — replacing the factory plastic cap with a more durable, heat-resistant threaded aluminum cap that maintains a secure seal over long-term use

Key Features

• T6 Aluminum Construction: Manufactured from high-grade T6 aluminum — significantly more heat-resistant and durable than the factory plastic tank. T6 aluminum will not crack, warp, or degrade from the heat cycling and coolant exposure that eventually destroys OEM plastic overflow tanks
• Clear Anodized Silver Finish: Clear anodized silver finish provides corrosion protection and a clean, premium underbay appearance — a significant visual upgrade over the factory plastic tank
• Direct Fit – 1995–1998 Nissan S14 240SX: Engineered as a direct-fit replacement for the factory coolant overflow tank on the 1995–1998 Nissan S14 240SX — uses factory mounting points for straightforward installation
• P2M Lifetime Warranty: Backed by P2M's signature lifetime warranty — a strong indicator of confidence in the Gen-2 design's long-term durability
