Good To Know
Q: Will this belt work on my Thermo King SLX 400? A: Yes, this belt is engineered to replace the factory 78-1340 belt used on SLX 400 and Spectrum models, but verify your serial number for exact compatibility.
Q: What happens if the water pump belt fails? A: A broken belt stops coolant flow, leading to engine overheating and potential compressor damage, so replace it promptly when worn.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
