The Wacker Neuson Overflow Bottle is a genuine OEM component designed for the CRT48-31V series ride-on concrete trowels. This includes the CRT48-31V, CRT48-31V-H High Speed, CRT48-31V-E, CRT48-31V-ES-E, and CRT48-31V-ES Electronic Steering models. As a direct OEM replacement, the matches the original specification to ensure the cooling system operates as designed. Sourcing the correct overflow bottle by part number is the most reliable way to confirm you are getting the right component for your machine.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and capacity specifications, ensuring the bottle holds and vents coolant at the correct pressure range for the CRT48-31V cooling circuit.
- Direct Drop-In Replacement: — Engineered to mount in the same location and connect to the same overflow hose fitting as the original, making installation straightforward on supported models.
- Broad CRT48-31V Family Coverage: — Confirmed fitment across five CRT48-31V variants, including the standard, High Speed, and Electronic Steering configurations of the 48-inch ride-on trowel.
- Protects Engine Cooling System Integrity: — A functional overflow bottle allows coolant to expand and return correctly; a cracked or missing bottle can lead to coolant loss, overheating, and unplanned engine damage during finishing operations.
- Verified Part Number Traceability: — Ordering by Wacker Neuson part number 5000150996 ensures the correct bottle geometry, volume, and fittings for this trowel platform — eliminating guesswork when replacing a damaged or degraded component.
The overflow bottle — also called a coolant reservoir or expansion tank — serves as the receiving vessel for coolant that expands as the engine reaches operating temperature. As the engine heats up, excess coolant is pushed from the radiator into the bottle; as it cools down, that coolant is drawn back into the system. This cycle keeps the cooling system sealed and at the correct fluid level. When the overflow bottle cracks, leaks, or is missing entirely, the engine loses the ability to recover that coolant, which can result in a progressively low coolant level, overheating, and potential engine damage — especially during the extended run times typical of large-area concrete finishing work.
