Diagram Ref No 15 (Diagram Ref No 16 Sold Separately)
What This Product Does:
- Transfers hot coolant from the engine to the radiator
- Enables proper heat dissipation
- Maintains stable engine operating temperature
- Supports continuous coolant circulation
Symptoms Of Wear Or Failure:
- Coolant leaks near the radiator or engine bay
- Engine overheating or rising temperature gauge
- Low coolant warning light
- Frequent coolant loss requiring top-offs
- Steam from under the hood
- Sweet coolant smell from the engine compartment
- Cracks, splits, or dry rot on the hose surface
- Swelling or bulging due to internal weakening
- Soft, spongy, or brittle hose texture
- Coolant residue or wetness around hose clamps and fittings
Why Replacement Matters:
- The upper coolant hose is responsible for carrying hot coolant from the engine to the radiator for heat removal. If the hose becomes worn, cracked, or weakened, it can leak or fail under pressure, causing rapid coolant loss.
- A failed upper hose can quickly lead to engine overheating, which may result in serious damage such as warped components or head gasket failure. Because this hose operates under high heat and pressure, replacing it when signs of wear appear is essential for maintaining cooling system reliability.
- Replacing the hose helps restore proper coolant circulation, prevent leaks, and protect the engine from costly overheating-related repairs.
