P2M Aluminum Coolant Overflow Tank – 1989–1994 Nissan 240SX / S13 Silvia

Replace the aged, cracked plastic reservoir in your S13 with the P2M Aluminum Coolant Overflow Tank — a direct-fit replacement specifically engineered for the 1989–1994 Nissan 240SX and S13 Silvia. After decades of heat cycling, the factory plastic overflow tanks are prone to cracking, leading to coolant loss and potential overheating. The P2M tank eliminates that failure point entirely.

Built from lightweight, high-strength T6061 aluminum with TIG-welded construction, this tank offers superior durability and a clean, race-inspired engine bay aesthetic over the OEM plastic unit.
