Radiator coolant hose – connects radiator and engine coolant passages as part of the primary cooling loop.

Function:
• Circulates coolant between the engine and radiator
•  Helps maintain optimal operating temperatures
•  Prevents coolant leaks and pressure loss
•  Contributes to engine reliability and longevity

Radiator hoses are continuously exposed to elevated temperatures, pressure fluctuations, and corrosive coolant chemicals. Over time, hoses can weaken, crack, swell, or become brittle, leading to:
•  Fluid leaks Engine overheating
•  Loss of coolant pressure
•  Potential engine damage.
Replacing aged or damaged hoses ensures the cooling system maintains integrity, prevents leaks, and continues to operate as intended by the manufacturer.

Replace this radiator coolant hose if:
•  Visible cracking, bulging, or soft spots
•  Evidence of coolant seepage or wet residue
•  Hoses feel mushy or stiff when squeezed
•  During routine coolant service or before long-term storage
•  If coolant system overhaul is being performed
