Purpose and fitment

The offered glass is designed as a component mounted on the front right side of the vehicle, in the door of a Ford Fiesta Mk5. The glass geometry matches the factory dimensions of the door opening, which allows for proper guidance in the tracks, tight closing, and compatibility with original seals and the window regulator mechanism. Using original Ford glass reduces the risk of adjustment issues, excessive wind noise, or leaks that may occur with dimensionally incompatible parts.

Characteristics of Green AS2 glass

The Green AS2 version is tempered side glass with a greenish tint, used as standard in many Ford models. This type of glazing:

• provides a pleasant, slightly tinted feel inside the cabin,
• reduces cabin heating on sunny days,
• maintains a color-consistent look with the vehicle's other windows. The tempered construction of the glass increases safety – in the event of damage, the glass shatters into small fragments with reduced edge sharpness.

Condition and benefits of choosing a used part

The glass comes from the secondary market, which means it is a used component. This type of part, when quality is maintained, represents a reasonable compromise between cost and functionality, especially for post-accident repairs or replacement after mechanical damage. Choosing an original used window allows you to maintain factory fitment and mechanism performance parameters while reducing repair costs compared to a new element from an authorized network.

Installation and technical aspects

The glass is prepared for installation in the factory mounting points of the Ford Fiesta Mk5 door. When replacing, it is recommended to:

• check the condition of the door guides and seals,
• verify the correct operation of the window regulator,
• precisely align the glass in the guides to avoid stress and scratches. A properly installed window ensures smooth mechanism operation, even closing, and proper acoustic and water tightness.
