Gates 22243 Lower Radiator Coolant Hose Molded OE Replacement

The Gates 22243 is a factory-molded lower radiator coolant hose engineered as a direct OE replacement. Pre-shaped to match original equipment specifications, this curved hose features a centerline length of 17.5 inches and an inner diameter of 1.47" x 1.47" x 0.73", ensuring a precise, leak-free fit without modification.

Constructed with an EPDM tube and EPDM cover reinforced with synthetic fiber knit, this hose is built to resist heat, ozone, and chemical coolant degradation — the leading causes of hose failure in modern cooling systems. Gates engineers the tube specifically to resist electrochemical degradation (ECD), a galvanic reaction between coolant, metal fittings, and the hose that causes micro-cracking and premature failure.

Key Features:

• Factory-molded lower radiator hose position for direct OE fitment
• 17.5 in. overall centerline length; ID: 1.47" x 1.47" x 0.73"
• EPDM construction resists heat, ozone, and chemical coolant attack
• Engineered to resist electrochemical degradation (ECD)
• Pre-shaped to ensure a perfectly sealed connection under vacuum
• Meets SAE 20R4, Class D2 standards
• Temperature rated from -40°F to +257°F (-40°C to +125°C)
• Black finish; sold individually
• Backed by Gates' Lifetime Limited Warranty

Note: Gates recommends replacing hose clamps each time a new coolant hose is installed. Not intended for fuel or oil transfer applications.
