Wacker Neuson 1000305556 Diesel Cooler

The Wacker Neuson Diesel Cooler is a genuine OEM component designed for the TH627 compact track loader. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original unit installed at the factory — no guesswork on fit or compatibility. If your machine is running hot or the existing cooler is damaged or leaking, the is the correct direct replacement to restore proper thermal management to your drivetrain.

Key Features

• Genuine OEM Construction: — Built to Wacker Neuson's original design tolerances, ensuring correct flow rates and thermal transfer capacity for the TH627's diesel system.
• Direct-Fit Replacement: — Engineered to match the original mounting points, port sizes, and line connections of the factory-installed cooler for a straightforward swap.
• Confirmed TH627 Compatibility: — Verified fitment for the TH627 compact track loader (418-02), eliminating the risk of ordering the wrong cooler for your machine.
• Sustained Engine Protection: — A properly functioning diesel cooler keeps hydraulic and engine temperatures in check during heavy-duty digging and loading cycles, preventing heat-related wear and unplanned shutdowns.
• Fuel System Safety: — Maintaining correct diesel fuel and oil temperatures is critical to safe, stable machine operation; a compromised cooler can lead to overheating events that damage downstream components.

A diesel cooler regulates the temperature of diesel fuel or engine oil by transferring heat away from the fluid as it circulates through the cooler core. In compact track loaders like the TH627, this component plays a key role in protecting the engine and hydraulic system from heat buildup during sustained operation under load. When a diesel cooler fails — whether through a cracked core, a blocked passage, or a leaking connection — fluid temperatures can rise beyond safe operating limits, leading to accelerated wear, reduced power output, and potential engine damage.
