Gates 18827 Molded Heater Hose Overview

The Gates 18827 molded heater hose is an OEM-style coolant hose built for smaller, tighter engine compartments. Its factory-molded shape helps it route cleanly in applications where a straight hose will not follow the original path. This molded heater hose is made from EPDM and is approved for coolant, water, air, and marine use.

Key Features

  • Part number: 18827
  • EPDM construction for heater and coolant service
  • Factory-molded design for OE-style routing
  • End I.D.: 0.62 in. / 16 mm at both ends

  • Approved for coolant, water, air, and marine applications

Detailed Description

Gates 18827 is a molded heater hose designed for direct replacement in vehicles that use a formed hose path through a compact engine bay. The molded profile supports proper routing around nearby components, while the 0.62-inch inside diameter at both ends and 17.8-inch centerline length match the listed application dimensions. This part is a practical choice for service work on vehicles such as the Mercury Capri, Pontiac 6000, Chevrolet Celebrity, Toyota Tercel, Buick Century, Oldsmobile Cutlass Ciera, and Oldsmobile Cutlass Cruiser when the original hose follows the same molded layout.

This part cross-references Dayco 87678 and Continental 63159 for the same application.

What It Helps Fix

  • Coolant leaks from a cracked or aged heater hose
  • Restricted coolant flow caused by hose collapse or softening
  • Poor hose routing in tight engine compartments
  • Heat-related deterioration in molded heater hose assemblies
  • Service replacement for heater-to-engine and valve-to-engine hose paths
