Key Features
- Genuine OEM Construction: — Engineered to the same pressure tolerance and material spec as the original coolant overflow bottle, maintaining proper cooling system function under operating temps.
- Direct-Fit Replacement: — Mounts in the original bracket position and connects to the existing radiator overflow hose, keeping installation clean and straightforward.
- Broad Series Compatibility: — Confirmed fitment for WRS5200DFPU, WRS5200, WRSPUDF ride-on roller screeds and HTXG6DF ride-on power trowels.
- Cooling System Integrity: — A functioning overflow bottle allows coolant to expand and contract safely; a cracked or missing bottle can lead to coolant loss, overheating, and unplanned engine shutdowns.
- Verified OEM Part Number: — Part number 21740 is the Multiquip-assigned OEM reference, so you can cross-check against your machine's parts manual with confidence.
The radiator overflow bottle — also called a coolant reservoir or expansion tank — serves as a holding chamber for coolant that expands as the engine reaches operating temperature. As the engine cools down, that coolant is drawn back into the radiator, keeping the system properly filled at all times. When the bottle cracks, splits, or its cap seal fails, the cooling system loses its ability to manage this pressure cycle correctly, which can cause the engine to run low on coolant and overheat without warning.
