Coolant Expansion Bottle Cap 145kPa / 21psi – Ford Fiesta / EcoSport / Ranger / Everest / Focus

Coolant Expansion Bottle Cap – 145 kPa / 21 psi – Ford OEM Replacement

A faulty or worn coolant bottle cap is one of the most overlooked causes of coolant loss and overheating. The cap maintains the correct pressure in the cooling system — when the seal or pressure valve fails, coolant boils off, the system loses pressure, and your engine runs hot. It’s a small part that does a very important job.

This direct-fit replacement cap is rated at 145 kPa / 21 psi — the correct specification for these Ford models — and features the integrated spring-loaded pressure relief valve visible on the underside for safe, controlled pressure release.
