Wacker Neuson 1000133255 Water Cooler Hose

The Wacker Neuson is a genuine OEM Water Cooler Hose designed for PT6Y and PT6YT series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this hose meets the original design specifications for the cooling circuit on these high-output 6-inch discharge pumps. Fitment covers the PT6Y, PT6Y EPA T4, PT6YT, and PT6Y-AU variants, making it a reliable choice for operators running any configuration within the PT6Y family. When the cooling hose degrades or leaks, engine temperatures rise quickly — replacing it promptly with the correct OEM part protects the engine and keeps the pump operating at full capacity.

Key Features

• OEM-Grade Hose Construction — Manufactured to Wacker Neuson's original material and pressure specifications, ensuring proper flexibility, heat resistance, and a secure seal within the cooling circuit.
• Drop-In Cooling Circuit Fit — Engineered to match the original routing and connection points on PT6Y and PT6YT pumps, allowing straightforward installation without reworking fittings or clamps.
• Broad PT6Y Family Coverage — Compatible with PT6Y, PT6Y EPA T4, PT6YT, and PT6Y-AU configurations, covering the full range of this 6-inch trash pump series.
• Protects Against Engine Overheating — A failed or cracked cooling hose disrupts coolant flow and can lead to rapid overtemperature conditions; a correct replacement restores proper thermal management immediately.
• Fuel System and Cooling Integrity — As a component within the engine cooling circuit on diesel-powered pump equipment, maintaining hose integrity is essential to safe, continuous operation on demanding pump applications.

The Water Cooler Hose routes coolant between the engine and the cooling system components on the PT6Y and PT6YT trash pumps. It keeps engine temperatures within a safe operating range during sustained pumping operations by allowing coolant to circulate continuously through the system. When this hose cracks, hardens, or develops a leak, coolant loss occurs rapidly, exposing the engine to overheating damage that can sideline the pump entirely — making timely replacement with the correct OEM part critical to uninterrupted operation.
