ACDelco 85119166 Radiator Inlet Coolant Hose

The ACDelco 85119166 is a radiator inlet (upper) coolant hose designed as a direct-fit replacement for select GM vehicles. Engineered to meet original equipment specifications, this hose delivers a precise, leak-free fit without modification, making it a reliable choice for cooling system maintenance and repair.

ACDelco radiator hoses are constructed from high-quality EPDM (ethylene propylene diene monomer) rubber, providing excellent resistance to heat, ozone, and coolant degradation over the long term. The reinforced construction helps the hose maintain its shape under pressure and extreme temperature cycles, reducing the risk of collapse or burst failure.

Key Features:

• Direct OE replacement for a precise, leak-free fit
• EPDM rubber construction for superior heat and ozone resistance
• Reinforced inner lining resists coolant degradation and collapse
• Designed and tested to meet GM original equipment standards
• Slip-fit end design (Position 1) for straightforward installation
• Maintains proper coolant flow between the engine and radiator

As part of ACDelco's extensive cooling system product line, the 85119166 inlet hose helps maintain optimal engine operating temperature, protecting against overheating and extending engine life. It is an ideal replacement during cooling system flushes, thermostat service, or any time hose cracking, swelling, or leakage is detected.
