Multiquip 21947 Rad Bottle Mount Bracket

The Multiquip 21947 Rad Bottle Mount Bracket is a genuine OEM component designed for HTX44 and STXD6i series hydrostatic ride-on power trowels. This OEM part is sourced directly through Multiquip's authorized parts network, ensuring it meets the exact specifications of the original component it replaces. Confirmed fitment includes the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STXD6i, and HTXD6i. DHS Equipment stocks Multiquip 21947 to keep your trowel cooling system properly supported and your machine running without interruption.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the bracket holds the coolant reservoir securely in its correct mounting position without flex or fatigue.
• Direct Bolt-On Installation — Engineered to align with the existing mounting points on HTX44 and STXD6i frame assemblies, so installation follows the original service procedure without modification.
• Broad HTX and STX Series Fitment — Compatible with HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, and STXD6i hydrostatic ride-on trowels.
• Cooling System Integrity — Keeps the coolant overflow bottle correctly positioned relative to the radiator, supporting consistent coolant recovery and proper overflow routing during operation.
• Built for Heavy-Use Environments — The bracket is designed to withstand the vibration and heat exposure typical of ride-on trowel engine compartments during extended finishing operations.

The rad bottle mount bracket secures the radiator overflow or coolant reservoir bottle to the machine's frame, holding it in the correct position for the engine cooling system to function as intended. Without a secure mount, the reservoir can shift or disconnect, disrupting coolant overflow routing and potentially leading to overheating or coolant loss during operation. Replacing a damaged or missing bracket promptly protects the broader cooling system and helps maintain consistent engine operating temperatures on the job.
