Gates 21956 Radiator Coolant Hose - Lower

Gates 21956 Molded Coolant Hose Overview

The Gates 21956 molded coolant hose is an OE-style replacement for lower radiator and HVAC coolant routing on select Dodge trucks and vans. Built from EPDM and formed to the correct molded shape, it helps restore proper coolant flow in applications that need a precise fit.

Compatible With 1992-1997 Dodge Dakota, B-Series vans, Ram vans, Ramcharger, and select D/W-series trucks, this Gates Molded Coolant Hose line is built for direct replacement use where the original hose follows a formed path. The 21956 part number is a practical choice when replacing a worn lower coolant hose on a vehicle that also uses HVAC coolant routing.

Key Features

• EPDM construction for coolant-system service
• Molded hose shape for routing accuracy

Product Line Details

Gates Molded Coolant Hose products are built for replacement applications that require a formed hose rather than a straight universal length. The line covers upper, lower, bypass, heater, and other coolant routing needs, giving technicians a direct-fit option for common OE-style hose layouts. Part number 21956 follows that approach for specific Dodge cooling-system applications.

Detailed Description

Gates 21956 is a molded radiator coolant hose made for lower-position cooling-system service on 1992-1997 Dodge applications. The EPDM material is suited for coolant exposure, while the molded profile helps maintain the original hose path and connection geometry. With a 1.75-inch inside diameter at each end and a 20.5-inch centerline length, this hose is specified for vehicles that require those dimensions and a formed lower hose layout. If you are replacing a lower radiator hose on a Dodge Dakota or a Dodge Ram van, the Gates 21956 provides a direct replacement format that supports clean routing and proper fitment.

What It Helps Fix

• Coolant leaks from a cracked or aged lower hose
• Softening, swelling, or collapse in the original hose
• Improper routing after a previous hose replacement
• Loss of coolant flow through the lower radiator circuit
• HVAC coolant hose service on listed Dodge applications

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length against the removed part before installation. Inspect clamps, necks, and nearby fittings for corrosion or wear, and replace damaged components as needed. Confirm the hose is seated fully and routed without twists or contact points that could cause premature wear. Fits 1992-1997 Dodge Dakota, lower; Fits 1995-1997 Dodge B1500, lower; Fits 1995-1997 Dodge Ram 1500 Van, lower.
