Good To Know

Q: How do I know if this belt fits my Thermo King unit? A: Confirm the model number (T-1000 or T-1200) and check the existing belt part number against 78-1669 or cross-reference CP-10506.

Q: What happens if the drive belt is too loose? A: A loose belt will slip, causing poor compressor output and overheating of the belt itself. Proper tension is required to maintain refrigeration performance.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
