FAQ Q&A

Q: How do I know if this radiator cap fits my specific vehicle?

A: Compare your original cap's part number with 16401-31650 or 16401-20353. This cap is specifically designed for Toyota Camry, Corolla, Highlander, and Lexus platforms using these specifications.

Q: Can I open the radiator cap while the engine is hot?

A: No, never open a radiator cap when the engine is hot. Wait for the engine to cool down completely to avoid high-pressure steam or coolant spraying and causing severe burns.

Q: Why is it important to replace a worn radiator cap?

A: A worn cap may fail to hold pressure or allow air into the system, leading to overheating, coolant loss, and eventual engine damage. Replacing it maintains the correct system pressure.
