Gates 21822 Molded Coolant Hose Overview
The Gates 21822 molded coolant hose is an OE-style radiator coolant hose built for upper cooling system applications that require a formed EPDM hose with OEM-quality dimensions. It is a direct replacement option for select Chevrolet Astro, GMC Safari, and Cadillac upper hose applications where the original hose routing and fit matter.
Gates Molded Coolant Hose products are built for a wide range of upper, lower, bypass, heater, and other coolant routing needs. This line is engineered to match replacement requirements across many vehicle platforms, helping reduce the time spent sourcing a dealer-only radiator hose replacement.

Product Description
Built as a molded radiator coolant hose, Gates 21822 follows the shape needed for specific upper hose routing instead of relying on a universal straight hose. The EPDM construction is suited for coolant exposure, while the 1.25-inch end diameters and 29.9-inch centerline length support the correct fit on listed applications. This part cross-references Dayco 71557 and FEL-PRO 61352 for the same application.
Search terms such as 1995 Chevrolet Astro upper radiator hose, 1995 GMC Safari upper coolant hose, and 1985-1987 Cadillac DeVille upper hose all point to the same type of formed replacement part. The Gates 21822 is also referenced across multiple interchange numbers, making it a practical match when replacing an aging molded hose on these vehicles.
Common Problems This Hose Can Address
- Cracked or hardened upper radiator hose material
- Coolant leaks at the hose body or formed bends
- Incorrect hose routing from a previous replacement
- Fitment issues caused by using a non-molded hose
- Cooling system service on select Chevrolet Astro, GMC Safari, and Cadillac models
Installation Notes
Verify hose routing against the original part before installation. The 1995 Chevrolet Astro and 1995 GMC Safari listings note that a protective sleeve is required and the hose must be cut to fit. Confirm clamp locations, inspect adjoining necks for wear, and replace any damaged clamps or sealing surfaces during service.
Quality Assurance
Gates manufactures this molded coolant hose to OEM-quality specifications for the listed applications. The Gates 21822 is part of a broad replacement hose line designed to cover upper, lower, bypass, heater, and other coolant system needs.
