CATERPILLAR-C9-NOZZLE-COOLING-BOLT

6V3940 is a nozzle cooling bolt for the Caterpillar C9 engine, a smaller fastener specific to the injector cooling circuit rather than the main structural bolts elsewhere on this engine. It's an easy part to overlook during injector service since it's not a headline component, but a bolt that's not torqued correctly here can allow a coolant leak directly into the injector bore — worth getting right rather than reusing an old one that's lost its sealing washer integrity.
