Heated Mirror Glass Specifications

heated mirror glass is a service replacement selected by OE reference for trucks compatible with VOLVO, used to restore a clear rear view when the existing glass is cracked, loose, or degraded by weather and road spray. OE references covered in this listing include 21070768, 20589798, and 21320365. Packing weight: 0.62 kg. Packing: 1 pc per box. Fitment should be confirmed by OE reference and mounting configuration before ordering.

In daily fleet operation, a stable mirror surface matters for lane changes, reversing, and coupling. This heated mirror glass supports consistent visibility in wet and cold conditions when the 24V heating function matches the vehicle’s mirror system and the glass seats evenly on a clean carrier. A correct selection should match the removed glass by outline, curvature, and mounting interface, then sit flush with uniform edge contact to reduce rattling and vibration blur at speed.

Typical application listings include trucks compatible with VOLVO FH (EU, 2005), FM (EU, 2005), and FM (4) (EU, 2012). Some catalog notes may mention a 300° specification; always verify the physical mirror head configuration on the vehicle before installation. After fitting, confirm stable adjustment, check that the glass is fully seated, and perform a short road test to ensure the heated mirror glass remains steady under vibration.

Service steps

1) Confirm OE references and compare outline/curvature with the removed glass.

2) Clean the carrier surface and check the mounting interface before fitting.

3) Seat evenly to achieve uniform edge contact; verify stable seating and visibility on a short road test.
