Removal Of Liquid Gasket Sealing

WARNING: This page is about a different car, the 2013 Infiniti FX50. However, it is still accessible from the selected car via links, so may be relevant.

After removing mounting nuts and bolts, separate the mating surface using the seal cutter [SST: KV10111100 (J-37228)] (A) and remove old liquid gasket sealing.
CAUTION: Be careful not to damage the mating surfaces.
Tap the seal cutter to insert it (B), and then slide it (C) by tapping on the side as shown in the figure below.
In areas where the seal cutter is difficult to use, lightly tap the parts using a plastic hammer to remove it.
