Frequently Asked Questions

Why is my 'Check Engine' light on after refueling?

A common cause for the 'Check Engine' light is a loose, cracked, or missing gas cap. The cap seals the Evaporative Emission Control (EVAP) system. If the seal is broken, the system detects a leak, triggering the light. Replacing the cap with a compatible, tightly sealing model usually resolves this issue.

Do I need to match the pressure rating on my radiator cap?

Yes, absolutely. The pressure rating (measured in PSI or kPa) is critical. The cap raises the boiling point of the coolant, preventing overheating. Using a cap with a lower rating will cause premature boiling; using one with a higher rating can damage hoses and gaskets. Always match the OEM pressure rating.

Are metal tire valve stem caps better than plastic ones?

Metal caps offer better durability and a more secure fit, often including a plastic or rubber liner for a superior air seal. While plastic caps are inexpensive and effective at keeping dirt out, metal caps provide better protection against corrosion and potential slow leaks, especially for vehicles with TPMS (Tire Pressure Monitoring System).
