Gates 52111 Radiator Coolant Hose - Lower - Pipe To Engine

Gates 52111 Molded Coolant Hose Overview

The Gates 52111 molded coolant hose is an OE-style radiator coolant hose built for upper, lower, bypass, heater, and other cooling system routing needs. Made from EPDM and formed to OEM-quality specifications, it supports a precise replacement for vehicles that require a molded hose with a 2.4 in. (61 mm) inside diameter at both ends and a 13.38 in. (340 mm) centerline length.

Gates Molded Coolant Hose products are engineered as direct-fit replacement hoses for common cooling system service work, helping reduce the time spent sourcing a dealer-only radiator hose replacement. The Gates 52111 is part of that molded hose line and is built for consistent fit and routing in applications such as Honda Civic and Toyota Corolla cooling system repairs where the correct molded shape matters.

Key Features

• EPDM construction for coolant-system durability
• 2.4 in. (61 mm) inside diameter at both ends
• 13.38 in. (340 mm) centerline length
• Molded shape for accurate hose routing
• No spring included
• OE-quality replacement for radiator coolant hose service

Detailed Product Description

This Gates 52111 radiator coolant hose is designed for cooling system applications that require a molded hose with matching end diameters and a specific formed profile. The EPDM material is commonly used in coolant service because it is suited to heat and fluid exposure in engine bay environments. With no branch quantity and no spring, the hose follows a straightforward molded configuration for direct replacement use.

For Honda Civic and Toyota Corolla owners servicing a leaking or deteriorated coolant line, the Gates 52111 provides a practical replacement option when the original hose shape and dimensions must be matched closely. This part cross-references Interchanges (e.g., 0521991000) for the same application.

Common Cooling System Issues It May Address

• Coolant leaks from cracked or aged radiator hose material
• Softening, swelling, or collapse in an original molded hose
• Improper hose routing after prior cooling system repairs
• Loss of coolant from a damaged upper, lower, bypass, or heater hose
• Fitment problems when a straight hose cannot match the factory bend

Installation Notes and Tips

Verify the hose length, molded shape, and both end inside diameters before installation. Compare the original hose routing on the vehicle to the Gates 52111 to confirm the formed profile matches the cooling system path. Inspect adjoining necks, clamps, and coolant passages for wear or corrosion before installing the replacement hose.

For best results, drain coolant to a safe level, remove the old hose carefully, and route the new hose without twisting it. Confirm clearance around nearby belts, pulleys, and hot engine components after installation.
