Wacker Neuson 5200004865 Upper Radiator Pipe G70 T4I

The Wacker Neuson Upper Radiator Pipe G70 T4I is a genuine OEM coolant pipe designed for the G70 portable generator series. This part is a direct OEM replacement sourced from Wacker Neuson, ensuring correct fitment across multiple G70 configurations including the Standard T4i, Custom T4i, Cold Weather T4i, Extended Run T4i, Hertz T4i, and URI HVAC variants. Keeping your cooling system's upper circuit sealed and flowing correctly is critical on a generator that's expected to deliver steady power output under continuous load. Genuine OEM quality means this pipe matches the original material spec, diameter, and end fittings exactly as designed for the G70 platform.

Key Features

• OEM-Grade Coolant Integrity — Manufactured to Wacker Neuson's original material and pressure specifications, so the upper coolant circuit maintains a proper seal under engine operating temperatures.
• Drop-In Fitment for G70 T4I Platforms — Engineered to connect directly to the G70's upper radiator port and engine coolant outlet without modification, using the same end geometry as the factory-installed pipe.
• Broad G70 Series Coverage — Compatible with G70 Standard T4i, Custom T4i, Cold Weather T4i, Extended Run T4i, Hertz T4i, and URI HVAC configurations, making it the correct part for the full G70 T4i lineup.
• Protects Against Overheating — A cracked or collapsed upper radiator pipe restricts coolant flow to the radiator, risking engine overtemperature and unplanned generator shutdown; replacing it promptly restores full thermal management.
• Genuine OEM Part Number 5200004865 — Supplied directly within the Wacker Neuson parts chain, so part number accuracy and fitment confidence are built in from the source.

The upper radiator pipe carries heated coolant from the engine's outlet to the top of the radiator, where the cooling cycle begins. It is a critical link in the engine's liquid cooling loop — if the pipe cracks, softens, or loses its seal at either end, coolant loss follows quickly, and the engine will overheat under load. On a portable generator like the G70, which is often run at sustained load for extended periods on a jobsite, a compromised upper radiator pipe can lead to thermal shutdown at exactly the wrong moment. Inspecting and replacing this pipe at the first sign of seeping or swelling keeps the cooling system operating at full capacity.
