Thomas Built Fan Belt

The Thomas Built Fan Belt drives your engine’s most critical accessories with the high-strength reliability that school bus fleets demand. This serpentine belt is built with Aramid fiber reinforcement—the same material used in ballistic armor—to provide incredible resistance to stretching and snapping under the high-heat conditions of an ISB engine bay. To ensure silent and efficient operation, the 8-rib profile is molded from advanced EPDM rubber, which stays flexible and crack-free even after years of exposure to ozone and road chemicals. By upgrading to this heavy-duty Thomas Built 180320 belt, you are protecting your alternator, water pump, and cooling fan from the sudden failures that lead to expensive roadside service calls and interrupted routes.
