Gates 19140 HVAC Heater Hose

Gates Molded Heater Hose 19140 Overview

The Gates 19140 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. Made from EPDM, it is shaped to match factory routing for reliable heater, coolant, water, and air transfer in select applications.

Compatible With Ford Ranger, Mazda B2300, Acura Integra, and Mitsubishi Diamante applications, this molded hose follows the original path needed for proper clearance and connection alignment. The Gates Molded Heater Hose line focuses on factory-molded replacement hoses for vehicles with compact underhood packaging.

Detailed Description

This molded heater hose is shaped to match factory routing and maintain proper hose alignment in confined engine bays. The Gates 19140 is used in heater, coolant, water, and air applications, and its EPDM material supports the demands of underhood fluid transfer. For buyers searching for a molded heater hose for Ford Ranger or Mazda B2300 service, this part provides the correct formed profile for listed positions such as heater inlet, heater outlet, heater to thermostat, and heater to pipe connections. The Gates 19140 also appears in applications for Acura Integra and Mitsubishi Diamante models.

The Gates Molded Heater Hose line is built around OE-style fitment for vehicles that require a pre-formed hose rather than a universal cut-to-fit section. That makes it a practical choice when replacing a worn or collapsed heater hose in a compact routing path.

What It Helps Address

• Coolant leaks from a cracked or aged heater hose
• Restricted coolant flow caused by hose collapse or softening
• Poor routing clearance in tight engine compartments
• Incorrect hose shape after a previous repair
• Heater circuit service on listed Ford Ranger, Mazda B2300, Acura Integra, and Mitsubishi Diamante applications

Installation Notes and Tips

Verify the hose position, end diameters, and centerline length before installation. This part is listed for specific heater-side locations, including heater - left side, heater inlet, heater outlet, heater to thermostat, and heater to pipe applications. Some listed vehicles note restrictions for air conditioning or emission configurations, so confirm the exact engine and HVAC setup before ordering. Use the vehicle’s factory routing path to ensure the molded shape aligns correctly with adjacent components.

Quality Assurance

Gates is known for OE-style hose construction, and this molded heater hose is built to factory-matched dimensions for the listed applications. Part number 19140 is a direct replacement option for select vehicles requiring a molded EPDM heater hose with the specified routing and connection size.
