Good To Know
Q: How often should this water pump belt be replaced? A: Inspect the belt every 500 operating hours and replace it if any cracks, glazing, or fraying is visible. In severe duty, replace it during every major service interval to avoid breakdowns.
Q: Can this belt work on older Thermo King units? A: This belt is designed for Precedent C-600 and S-600 models, but it may fit other units using the same 78-1340 length. Always compare the belt's rib profile and length with your existing belt before installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
