Wacker Neuson 5000215489 Thermostat Housing

The Wacker Neuson Thermostat Housing is a genuine OEM component designed for the RD16-90 and RD16-100 vibratory roller series, as well as the extensive DPU80, DPU90, and DPU110 reversible and standard plate compactor range. As a direct OEM replacement, this housing is produced to the exact tolerances and material specifications of the original part, ensuring correct thermostat seating and a leak-free coolant circuit. Whether you're servicing a tandem roller on a road project or a heavy-duty plate compactor on a foundation site, part number restores the cooling system to proper operating condition. Confirm your machine model against the fitment list before ordering to ensure compatibility.

Key Features

• OEM Coolant Sealing Integrity — Manufactured to original dimensional specs, ensuring the thermostat seats correctly and coolant passages seal without weeping or bypass leaks.
• Drop-In Installation — Matches the original bolt pattern, port orientation, and gasket surface of the factory housing for a straightforward swap with no reworking of coolant lines.
• Broad Fitment Across Two Equipment Families — Compatible with RD16-90 and RD16-100 vibratory rollers and a wide range of DPU80, DPU90, and DPU110 Lec, Lem, and Lekc series plate compactors, including US-spec variants.
• Protects Engine from Thermal Damage — A correctly functioning thermostat housing keeps operating temperature stable; a cracked or warped housing allows coolant loss, which quickly leads to overheating and potential engine damage.
• Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network under part number 5000215489, so you're getting the same component that shipped with the machine originally.

The thermostat housing is the structural enclosure that holds the engine thermostat in place within the cooling circuit, directing coolant flow between the engine block and the radiator based on operating temperature. When the engine is cold, the thermostat stays closed and the housing routes coolant internally to help the engine reach working temperature faster; once warmed up, the thermostat opens and the housing directs flow out to the radiator for cooling. If the housing cracks, warps, or develops a failed sealing surface, coolant escapes or bypasses the thermostat, causing erratic temperature swings, overheating warnings, and — if left unaddressed — serious engine damage.
