Ford Fiesta Coolant Cap: Function Introduction

The Ford Fiesta coolant cap is a critical component in your vehicle's cooling system. Its primary role goes beyond merely preventing coolant leakage; it ensures the pressure balance within the radiator, maintaining an optimal water level. As the coolant temperature rises and expands, the coolant cap comes into play.

How It Works

When the pressure exceeds the relief value of 0.9kg, the spring mechanism in the Ford Fiesta coolant cap activates. This allows the excess coolant to flow into the auxiliary tank for storage. Conversely, when the coolant temperature drops and a vacuum forms in the radiator, the cap opens to draw the coolant back, maintaining the water level balance.

Enhanced Features

Upgrading to a D1-SPEC temperature-measuring Ford Fiesta coolant cap provides accurate temperature readings without needing to start the engine. The silicone inner plug improves heat resistance and ensures a tighter seal, enhancing the overall performance of the cooling system.

Specialized Applications

The Ford Fiesta coolant cap is also ideal for off-road motorcycles equipped with a water temperature meter. This feature allows you to monitor the coolant temperature in real-time, preventing engine damage due to overheating. It is designed to be universally compatible with all types of water tanks.
