Gates 21205 Molded Coolant Hose Overview

The Gates 21205 molded coolant hose is an OE-style radiator coolant hose built for upper cooling-system routing on select GM vehicles. It uses EPDM construction and molded shaping to match the factory hose path for a cleaner, more direct replacement.

Compatible With 1980-1990 Buick LeSabre, 1980-1985 Chevrolet Impala, and other upper hose applications listed below, this part supports radiator and heater-circuit cooling service where a formed hose is required.

Key Features

  • EPDM rubber construction for coolant-system service
  • Molded design for factory-style routing and fit
  • Upper radiator coolant hose application
  • End 1 inside diameter: 1.25 in. (32 mm)
  • End 2 inside diameter: 1.56 in. (40 mm)
  • Centerline length: 26.4 in. (671 mm)
  • No spring, no modular sections, and no quick-connect fittings

Product Details

Gates Molded Coolant Hose line is engineered for upper, lower, bypass, heater, and other coolant applications using OEM-quality specifications. The molded shape helps the hose follow the original routing on vehicles such as the Chevrolet Caprice, Oldsmobile 98, and Pontiac Grand Prix, reducing the need to adapt a universal hose. Part number 21205 is also referenced as Gates 41093 in interchange data.

This hose cross-references Dayco 71030 for the same application.

Common Cooling Issues This Hose Can Address

  • Cracked or softened upper radiator hose material
  • Coolant leaks at a worn hose bend or formed section
  • Poor fit from a straight universal hose replacement
  • Heat-related hose swelling or collapse in service
  • Loss of proper coolant flow through the upper hose route

Installation Notes and Fitment

Verify hose routing, end diameters, and centerline length before installation. This molded hose is listed for upper-position applications only and should be matched to the vehicle’s original hose shape.
