Description

Overview

Radiator Cap Thermo King SB SL SB-III gives workshops and fleet operators a direct replacement option for compatible transport refrigeration units in the SB, SL and SB-III range. Use it when the original cap no longer seals well, shows wear or needs replacement during routine cooling system service. Because cooling components work under heat and pressure, a fresh cap helps maintain system integrity and can reduce the risk of coolant loss at the cap.

Features

• Radiator Cap Thermo King SB SL SB-III supports routine cooling system maintenance
• Fits compatible Thermo King SB, SL and SB-III applications
• Compact cap design allows quick inspection and replacement where access permits
• Helps fleets service older trailer refrigeration equipment with a straightforward replacement part

Compatibility and Fitment

Check the existing cap style and application before ordering, because transport refrigeration units can vary across model families and service history. This part is a suitable replacement for the part numbers and matching applications shown. Some changes in installation may be required. TK-11-5406, TK115406, 11-5406, 115406, 115-406, 11-5424, 115424, 11-4648, 114648, 94-1357, 941357

Compliance and Safety

Only remove and replace the cap when the cooling system is cool to the touch. Do not remove the cap while coolant remains hot. In addition, inspect the sealing surfaces and filler neck before you fit the new cap. If the neck shows damage or corrosion, cap replacement alone may not solve the issue.

Trailer Applications

Radiator Cap Thermo King SB SL SB-III suits trailer refrigeration maintenance where operators need a compatible replacement cap for older Thermo King equipment. It works well for workshop stock, preventative maintenance schedules and mixed fleet servicing. It also makes sense as a spare for units that run long regional routes, because cooling faults can quickly turn into downtime.
