Route engine coolant reliably with the Gates HVAC Heater Hose 51344. This direct-fit replacement hose is cataloged for the water pump-to-thermostat position and drops in for the 2000-2008 Jaguar S-Type. It carries hot coolant between the water pump and thermostat as part of the vehicle's cooling and heater circuit, restoring a leak-free connection when the original hose hardens, cracks, or seeps.
- Application-specific fit: shaped for the water pump-to-thermostat run on the listed Jaguar S-Type, so it follows the factory routing.
- Coolant duty: designed to handle the heat and pressure of circulating engine coolant.
- Direct replacement: installs in place of a worn, brittle, or leaking original hose.
Signs this hose may need replacing include coolant seepage or drips near the connection, a soft or swollen hose body, cracks, or low coolant level. If a failed hose is the cause of your leak, this replaces it; diagnose the source of any leak before replacing. Inspect clamps and connections during installation.
