Gates 19251 HVAC Heater Hose - Tee-1 To Auxiliary Water Pump

Gates Molded Heater Hose 19251 Overview

The Gates 19251 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. It is formed to match the factory path and is suitable for coolant, water, and air service, with marine application approval.

Compatible with 1999-2003 Volkswagen Beetle models at the tee-1 to auxiliary water pump position, this molded heater hose supports a precise fit in the Beetle cooling circuit. The Gates Molded Heater Hose line focuses on factory-shaped routing for vehicles that need a formed replacement rather than a universal hose.

Detailed Description

Gates 19251 is a molded heater hose formed to follow the original routing used in compact engine compartments. Its EPDM material and molded profile help it serve as a direct replacement style hose where a standard straight hose would not maintain the correct path or clearance. For Volkswagen Beetle cooling system service, this hose is listed for the tee-1 to auxiliary water pump position on 1999-2003 models. This part cross-references BBB Industries 11251 for the same application.

Common Problems It Can Help Address

• Cracked or leaking heater hose at the factory bend
• Poor hose routing in a tight engine compartment
• Cooling system seepage at the tee-1 to auxiliary water pump connection
• Replacement needs for a formed hose that matches OE-style routing
• Service on a 1999-2003 Volkswagen Beetle cooling circuit

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. Inspect adjoining fittings, clamps, and nearby coolant components for wear or corrosion, and confirm the hose follows the original molded path without twist or kinks. For Volkswagen Beetle applications, match the tee-1 to auxiliary water pump routing exactly to maintain proper clearance.
