Gates 18752 HVAC Heater Hose - Heater To Engine or Heater To Intake Manifold

Gates 18752 Molded Heater Hose

Gates 18752 is a molded heater hose built for tight engine bays where a factory-shaped coolant hose is needed for a clean, direct routing path. This Gates Molded Heater Hose uses EPDM construction and OEM-style forming to serve heater, coolant, water, and air routing needs, including marine applications.

Key Features

• EPDM construction for heater and coolant service
• Factory-molded shape for smaller, tighter-fitting engine compartments
• End I.D. sizes: 16 mm (.62 in) and 19 mm (.75 in)
• Centerline length: 312 mm (12.3 in)
• Direct replacement style for heater-to-engine and heater-to-intake-manifold routing
• Gates 18752 is approved for marine applications

Product Details

This molded coolant hose is engineered to follow the original routing used on select Chrysler, Dodge, and Plymouth vehicles. It is a practical choice for heater hose replacement on applications such as 1990-1995 Dodge Spirit, 1991-1995 Plymouth Acclaim, and 1991-1994 Chrysler LeBaron, as well as other listed models with heater-to-engine or heater-to-intake-manifold layouts. The Gates Molded Heater Hose line focuses on OE-style fitment for compact engine compartments, and part number 18752 reflects that approach with a pre-formed profile rather than a universal straight hose.

This part cross-references Dayco 87637 and Four Seasons 63168 for the same application.

Common Problems This Hose Can Address

• Cracked or leaking heater hose at the engine connection
• Incorrect hose routing in tight engine compartments
• Coolant loss from aged molded rubber hose sections
• Restricted heater circuit flow caused by deteriorated hose walls
• Replacement needs on heater-to-engine or heater-to-intake-manifold layouts

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. This Gates 18752 hose is listed for specific Chrysler, Dodge, and Plymouth applications, including some vehicles that are not compatible with AC-equipped configurations. Match the vehicle’s heater hose path to the fitment notes before ordering, and inspect adjoining clamps, fittings, and coolant connections for wear during service.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement built from EPDM material for coolant, water, and air service. The molded construction supports accurate routing in the listed applications, including select 1986-1995 Chrysler, Dodge, and Plymouth models.
