3. Now is the time to fix the radiator to the
radiator bracket. Apply anticorrosive seal-
ant (silicone sealant) to hatched areas, to
prevent corrosion. See the figure below.
Apply silicone sealant into threaded holes
on the scanner radiator. Remove the cap
on the radiator bracket and orient the ra-
diator bracket as shown in Figure 6-13.
Apply grease to the O-ring and set it to the
center of the radiator bracket. Coat the ra-
diator fixing bolts with silicone sealant.
Fasten the radiator to the radiator bracket
with the FURUNO logo on the radiator fac-
ing ship’s bow.
