Gates 19743 HVAC Heater Hose - Heater To Reservoir or Heater To Tank

Gates 19743 Molded Heater Hose

The Gates 19743 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. It is formed to match the application and is suitable for coolant, water, and air service, with marine application approval.

Compatible with 1992-1996 Chevrolet Corvette heater to tank and 1993-1995 Chevrolet Corvette heater to reservoir applications, this molded heater hose supports proper routing in the Corvette cooling and HVAC system. Gates Molded Heater Hose products are built around factory-style fitment for vehicles that need a shaped hose rather than a universal length.

• EPDM construction for coolant hose service
• Factory-molded shape for tighter engine bay routing
• OEM-style replacement for the Gates 19743 application
• Approved for coolant, water, air, and marine use
• Fits Chevrolet Corvette heater hose routing applications listed below

Application Details

Fits 1992-1996 Chevrolet Corvette, heater to tank. Fits 1993-1995 Chevrolet Corvette, heater to reservoir. This part cross-references Continental 64304 for the same application.

Use the Gates 19743 when the original hose has hardened, cracked, collapsed, or no longer follows the correct molded path. The shaped design helps maintain the intended hose route in the Chevrolet Corvette cooling and heater circuit, especially where clearance is limited.

Common Problems It Can Address

• Coolant seepage from an aged heater hose
• Cracking or splitting from heat cycling
• Collapsed hose sections that restrict flow
• Poor routing in compact engine compartments
• Incorrect fit from a non-molded replacement hose

Installation Notes and Tips

Match the hose to the vehicle year and heater connection location before installation. Inspect adjoining clamps, fittings, and nearby coolant lines for wear or corrosion, and verify the hose follows the original molded path without twisting. Confirm the routing clears moving parts and hot surfaces after installation.

Quality Assurance

Gates manufactures molded coolant hoses to OE-style specifications for application-specific fitment. The EPDM material and factory-molded construction support reliable service in the intended cooling and HVAC hose location.
