MULTI-MODEL - ENGINE UNDERCOVER HARD TO REMOVE

APPLICABLE MODEL(S)/VINS

2004 - 2007 Mazda3

2006 - 2007 Mazda5

2007 Mazdaspeed3

DESCRIPTION

On some vehicles, the undercover may be hard to remove because the clip-nuts are rusted on the bolts due to road salt. When this happens, the complete clip spins or the spot weld breaks and the nut spins separately from the clip when loosening the bolts. The clip-nuts can be serviced separately from the undercover, and modified clip-nuts are now available with the thread integrated into the clip base.

NOTE:

• The original bolts for the under cover (PN: 90720-0620) are 20mm long. In place of these bolts 16mm long bolts may be used (PN: 90720-0616). Although the 16 mm bolts are more difficult to align and install, less thread is exposed above the clip-nuts when used, reducing the chance of corrosion.

• Before installing the bolts, apply anti-seize compound to the bolts.

• Reuse the undercover if possible, however if it is broken, replace it with a new one.
