The Multiquip 21736 Radiator Bottle Bracket is a genuine OEM component designed for the STX55J6 and STX55Y6 hydrostatic ride-on power trowels. This bracket provides a secure, factory-correct mounting point for the radiator overflow bottle, ensuring the cooling system stays properly supported during operation. As a direct Multiquip OEM part, the 21736 is built to the same specifications as the original component installed at the factory. Confirm your model code before ordering to ensure proper fitment with your STX55 series machine.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring correct bracket geometry and mounting hole alignment for a clean, secure installation.
- Direct-Mount Replacement — Replaces the original bracket using existing hardware and mounting points on the STX55 frame, requiring no modification to surrounding components.
- STX55 Series Fitment — Confirmed for STX55J6 and STX55Y6 hydrostatic ride-on trowel models; verify your model code prior to ordering.
- Cooling System Stability — Keeps the radiator overflow bottle firmly positioned, preventing movement that could stress coolant hoses or cause overflow line disconnections during heavy finishing work.
- Long-Term Structural Integrity — A properly mounted overflow bottle supports consistent coolant reservoir function; a missing or damaged bracket can lead to hose strain and cooling system issues over time.
The radiator bottle bracket secures the coolant overflow reservoir to the machine's frame, keeping it stable and correctly positioned relative to the radiator. Without a functioning bracket, the overflow bottle can shift or become unsupported, placing stress on coolant hoses and potentially disrupting the engine's cooling circuit. Replacing a bent, cracked, or missing bracket is a straightforward step in maintaining the integrity of the cooling system on your ride-on trowel.
