Application Details

What It Helps Address

• Coolant leaks from cracked or deteriorated radiator hose material
• Improper hose routing caused by a misshaped replacement hose
• Softening, swelling, or collapse in an aging coolant hose
• Loss of cooling-system integrity at the hose connection points
• Fitment issues when replacing the original molded hose on Dodge Caravan, Dodge Grand Caravan, or Pontiac Fiero

Installation Notes

Verify the hose position, end diameters, and centerline length before installation. Confirm whether the vehicle uses the upper hose or lower engine-to-pipe routing shown in the fitment data. Inspect adjoining clamps, necks, and coolant passages for wear or corrosion before installing the new hose. Gates 21594 should be matched to the exact application listed for 1995 Dodge Caravan, 1995 Dodge Grand Caravan, and 1985-1987 Pontiac Fiero.
