The Wacker Neuson Overflow Bottle 1 Liter is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original equipment installed at the factory. Compatible across multiple HI 770 XHD configurations — including diesel units built to the Arctic Bear XHD, Arctic Bear XHD NS, and Extra Heavy Duty Air Heater specifications — the is a direct drop-in solution for machines that require overflow bottle replacement.
Key Features
- OEM-Matched Capacity: — 1-liter volume matches the original overflow bottle specification, ensuring correct coolant reservoir levels in the HI 770 XHD heating system.
- Direct Drop-In Fit: — Engineered to connect to existing hose fittings and mounting points without any modification to the heater unit.
- Broad HI 770 XHD Compatibility: — Fits Arctic Bear XHD, Arctic Bear XHD NS, and Extra Heavy Duty Air Heater variants of the HI 770 XHD platform.
- Thermal System Integrity: — A properly functioning overflow bottle maintains consistent coolant levels, preventing overheating and protecting the heat exchanger during heavy-duty continuous operation.
- Genuine Wacker Neuson OEM Part: — Manufactured to the same material and dimensional standards as the part it replaces, so you can be confident the bottle will seal and perform as intended.
The overflow bottle serves as the coolant expansion reservoir in liquid-cooled indirect air heaters like the HI 770 XHD. As the heater cycles through operating temperatures, coolant expands and contracts — the overflow bottle captures that excess fluid and returns it to the system as temperatures drop, keeping the cooling circuit properly filled at all times. A cracked, damaged, or missing overflow bottle can lead to coolant loss, inconsistent heating output, and potential overheating of internal components.
