Genuine part. Fitment information is for reference only. To ensure 100% compatibility, please send us a message with your VIN number before ordering.
Product Description
The genuine TOYOTA part number 16571-17010 coolant hose (upper radiator inlet hose) is an essential component of the engine cooling system. Its primary function is to provide reliable, leak-free routing of hot coolant from the engine block/cylinder head outlet to the radiator upper inlet. Manufactured to original factory specifications, it ensures continuous, unobstructed coolant circulation, protecting the engine from overheating and thermal shock.
Technical Specifications and Construction Features:
- Function: Radiator inlet hose (Hose, Radiator, Inlet)
- Manufacturer: Toyota (genuine OEM quality)
- Material composition: Heat- and chemical-resistant synthetic EPDM rubber with internal fabric reinforcement, resistant to coolant glycol, electrochemical degradation, and high internal pressure
- Design: Shape-retaining, pre-formed geometry that guarantees an exact, stress-free fit within tight engine bay spaces
- Installation location: Cooling system upper/inlet section
Role of the Radiator Hose and Typical Symptoms of Wear:
Cooling hoses are subjected to constant mechanical vibration, pressure cycling, and extreme temperature fluctuations. Over time, the rubber material may harden, soften, or crack. Common symptoms of failure include surface micro-cracking, leakage at connection points (clamps), hose bulging due to internal ply failure, and a gradual drop in coolant level. Hose damage can lead to sudden coolant loss and catastrophic engine overheating, making regular inspection and preventive replacement crucial.
