Gates 23453 Molded Coolant Radiator Hose 24.3 in. Lower Front Black

The Gates 23453 is a factory-molded OE replacement coolant hose designed for front lower radiator applications. Measuring 24.3 inches (617 mm) in centerline length with a 1.27-inch (32 mm) inside diameter, this hose is precision-shaped to meet original equipment manufacturer specifications for a direct, leak-free fit.

Key Features:

• Factory molded construction — pre-shaped to fit specific applications, matching OEM geometry for easier installation and a secure seal
• Re-engineered materials resist vacuum collapse — maintains hose integrity under the negative pressure conditions common in modern cooling systems
• Heat and ozone resistant cover — protects against the harsh under-hood environment for long service life
• Electrochemical degradation (ECD) resistance — engineered to combat the leading cause of coolant hose failure, where the hose, coolant, and metal fittings form a galvanic reaction that degrades the hose from within
• Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications — industry-standard compliance ensures consistent, reliable performance
• Approved for marine applications — versatile enough for both automotive and marine cooling system use
• Not for fuel or oil transfer — designed exclusively for coolant, water, and air applications
• Sold individually — spring not included
• Lifetime Gates limited warranty

Suitable for upper, lower, by-pass, heater, and other coolant hose positions, the Gates 23453 delivers OEM-quality performance at an aftermarket value. Gates recommends replacing hose clamps each time a new coolant hose is installed.
