Gates 19151 HVAC Heater Hose - Valve To Engine

Gates 19151 Molded Heater Hose Overview

Gates 19151 is a molded HVAC heater hose built for tight engine bays where a factory-shaped coolant hose is required. It uses EPDM construction and a small inside diameter to support coolant, water, and air routing in applications that demand an OEM-style bend profile.

This molded heater hose is listed for 1999-2000 Acura EL and 1999-2000 Honda Civic, valve to engine. If you are replacing a worn heater hose on a Honda Civic or Acura EL, Gates 19151 provides the correct molded routing for those applications.

Key Features

• Factory-molded, OEM-style hose shape for compact engine compartments
• EPDM material for heater and coolant service
• End I.D.: 0.65 in. / 17 mm
• Centerline length: 16 in. / 406 mm
• Approved for coolant, water, air, and marine applications
• Direct fitment for valve-to-engine routing on select Acura and Honda models

Detailed Description

Gates Molded Heater Hose 19151 is part of the Gates Molded Heater Hose line, which focuses on pre-formed hose routing for modern vehicles with tighter packaging around the engine. The molded design helps match the original hose path, reducing the need to force a straight hose into a curved route. For 1999-2000 Honda Civic and 1999-2000 Acura EL applications, this hose supports the valve-to-engine connection with the correct molded profile.

This part cross-references Continental 64162 for the same application.

What It Helps Solve

• Cracked or leaking heater hose at the valve-to-engine route
• Incorrect hose shape that does not follow the original engine bay path
• Restricted coolant flow caused by a deteriorated hose interior
• Service issues in compact engine compartments where straight hose will not route cleanly
• Replacement needs for molded coolant, water, or air hose service

Installation Notes and Tips

Verify the hose path, end inside diameter, and centerline length before installation. Confirm the vehicle application as 1999-2000 Acura EL or 1999-2000 Honda Civic, valve to engine, and compare the original hose shape to Gates 19151 before final fitment. Inspect adjoining clamps, fittings, and nearby coolant components for wear or corrosion during service.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement part for the listed applications. The EPDM construction and factory-molded profile support consistent fitment in the specified vehicle applications.
