Gates Radiator Cap P/N:31523

Hold cooling-system pressure and help keep coolant at its proper boiling point with the Gates Radiator Cap 31523, a Standard Vented Cap that seals the radiator filler neck and manages pressure as the engine heats and cools. It's a direct-fit replacement across a huge range of applications — including the 1988-1999 Chevrolet C1500 and K1500, 1994-1998 Dodge Ram 1500, and the 1977-2003 Buick Century, LeSabre and Regal, plus more than a thousand additional vehicles listed in the Buyer's Guide tab.

This OE Performance grade cap is engineered for precise pressure control, with an application-specific vent valve that releases excess pressure and a vacuum-relief valve that opens on cooldown to draw coolant back from the recovery tank.

• Pressure control: rated at 16 psi with application-specific vent and vacuum-relief valves.
• Durable build: constructed of corrosion-resistant, heavy-gauge metal or high-quality plastic, depending on the application, for long service life.
• Direct fit: shell outside diameter 2.33 in, cap depth 1.25 in, sized to the standard filler neck (1.61 in / 41 mm inside diameter).
• Easy install: requires no adjustment for installation.

Works with either an optional coolant recovery system or a standard setup. Country of origin: China.
