Product Details

Stant Safety Release Radiator Cap 10330 is built around a 16 PSI pressure rating, which is the critical specification for matching the cooling system requirements listed in the fitment data. This radiator cap is used on many vehicles, including Dodge Grand Caravan, Ram 1500, and Jeep Wrangler applications, as well as a broad range of Chrysler, GMC, Chevrolet, Ford, and Jeep models across multiple years. The Lev-R-Vent design supports pressure control while helping move coolant back from the overflow reservoir when the system cools down.

This part cross-references OE-style radiator cap applications where a 16 psi safety release cap is specified.

What It Helps Address

• Coolant loss through the overflow tank
• Pressure-related radiator cap failure
• Cooling system pressure instability
• Improper cap sealing on specified applications
• Temperature control issues tied to a worn cap

Installation Notes and Tips

Verify the radiator neck and system specification before installation. Match the 16 psi rating to the vehicle requirement and confirm the cap style is correct for the application. Inspect the radiator filler neck, seal surface, and overflow hose routing for wear or damage before replacing the cap. For fitment examples, this part fits 2013-2018 Dodge Grand Caravan, N/A; fits 2011-2018 Ram 1500, N/A; and fits 2015 Jeep Wrangler, N/A.
