This is a Genuine Nissan oil cooler hose designed specifically for Thai-built Nissan Navara D40 models equipped with the YD25 engine. As a critical component in the automatic transmission cooling system, this hose connects the front barb of the oil cooler to an upper adapter near the back of the engine block, ensuring proper circulation of transmission fluid.
Over time, the original rubber hose can perish, crack, or become brittle from constant exposure to engine bay heat and fluid pressure. Replacing a worn or leaking hose is essential maintenance to prevent the loss of transmission fluid, which can lead to overheating and serious transmission damage.
Replacement is a moderate task for a competent home mechanic or a routine job for a workshop. This process will require the automatic transmission fluid to be drained and refilled. You will need fresh, correct-specification transmission fluid to complete the job. It is also good practice to inspect the hose clamps and replace them if they show signs of wear or corrosion.
Please check vehicle fitment to confirm compatibility with your vehicle. Please contact us with your VIN details if you require further assistance to confirm fitment.
