Designed for the KIT D4D/D6D, the 20459212 oil cooler kit d4d/d6d provides effective heat dissipation for the engine or hydraulic circuit — critical for preventing overheating and protecting internal components. A failed or leaking cooler allows engine temperatures to climb beyond safe limits, risking head gasket failure, warped components, and catastrophic engine damage. Manufactured to OEM reference 20459212 for accurate installation on the KIT D4D/D6D and immediate restoration of cooling capacity.

Key Features:

  • Full Cooling Capacity: Restores rated heat transfer performance to maintain engine temperatures within OEM specification.
  • OEM Compatible: Built to reference 20459212 for compatible fitment on the KIT D4D/D6D.
  • Leak-Free Cooling Circuit: Precision-sealed construction prevents coolant or fluid loss from the heat exchanger.

The 20459212 oil cooler kit d4d/d6d is a critical thermal management component for preventing overheating and protecting engine integrity on the KIT D4D/D6D.

What Does This Oil Cooler Core Do?

A heat exchanger that passes hot engine oil or hydraulic oil through a matrix of fins and tubes, allowing coolant or air to carry away excess heat. Keeps oil temperature within the safe operating range to maintain viscosity and lubrication performance under sustained heavy load.

Possible Oil Cooler Core Problem Symptoms

If your machine is showing any of the following, a faulty oil cooler core may be the cause:

  • Engine or hydraulic oil temperature rising above normal operating range
  • Oil discolouration or milky appearance, indicating coolant mixing with oil through a failed core
  • External oil or coolant leaks visible at the cooler core body or sealing surfaces
  • Machine entering thermal protection mode or de-rating power output under sustained load
