engineered for Reliability and Leak-Free Operation
This replacement assembly is built to withstand the unique challenges of the under-hood environment, focusing on flexible durability and secure connections.
Coolant & Heat Resistant: Constructed from specially formulated EPDM rubber, this hose resists degradation from prolonged exposure to hot coolant, ethylene glycol, and extreme engine bay temperatures, preventing softening, cracking, and premature failure.
Leak-Free Connections: Features molded, pre-shaped ends with reinforced OEM-style clamps that ensure a tight, secure seal at the engine block and heater core connections, preventing costly coolant loss.
Precision OEM Shape: Manufactured to exact original specifications, including precise bends and lengths, this assembly guarantees a perfect fit without kinking or stress on the connections, ensuring unobstructed coolant flow.
Abrasion Resistance: The durable outer cover protects against wear from contact with adjacent components, extending the service life of the hose.
Identify a Failing Heater Hose Assembly (OE# 12590279):
Watch for these signs that indicate the need for replacement:
Loss of Cabin Heat: A primary symptom. Inadequate hot coolant flow to the heater core will result in little to no heat coming from the vents.
Visible Coolant Leaks: Puddles of sweet-smelling, brightly colored fluid (often green, red, or orange) under the front passenger side of the vehicle.
Engine Overheating: A significant leak can lead to low coolant levels, causing the engine temperature gauge to rise into the danger zone.
Swelling, Softness, or Cracks: Upon inspection, the hose may feel soft, show visible bulges, or have surface cracks.
