 Adding a [[RadGuard|Radiator Stone Guard]] is highly recommended.
-The fixing of the radiator overly hang it from the two fixings at the top rather than seat it on the fixing below it. This causes a telltale breaking of a core at the rear of the radiator close to the upper fixing point near to the expansion tank.

This causes a telltale breaking of a core at the rear of the radiator close to the upper fixing point near to the expansion tank. This [[https://www.apriliaforum.com/forums/showthread.php?262154-radiator-hole&highlight=chemical+metal|Aprilia Forum post]] shows what usually happens.
-Many report that adding a thick washer underneath the bottom fixing point pushes teh rad up enough to stop these stesses.
+Many reports that adding a thick washer underneath the bottom fixing point pushes the rad up enough to stop these stresses passing through the cores.
+However, if you have a hole, aluminium brazing is unlikely to work as it is so thin it melts so easy and the rad holds so much microscopic dirt heat applied tends to flash and bang.
+The best way to do it is to open up the broken core with a screwdriver and stuff it full of chemical metal, epoxy resin then build it up around the fault to ensure it can't expand and contract to continue the crack further down the core. It will look messy but done well it will be entirely permanent.
+One or two missing cores will not cause the cooling system to run any warmer.
