Product Details

Gates 19498 is a molded HVAC heater hose engineered to follow the original hose path in vehicles with limited clearance around the engine. The EPDM material helps the hose handle common thermal and fluid demands found in heater and coolant circuits, while the molded profile supports a cleaner, more accurate routing than universal hose shapes. This part cross-references Four Seasons 19498 for the same application.

Use Gates 19498 when replacing a worn or damaged molded heater hose on vehicles such as the Honda Civic, Honda Accord, and Acura TSX. The part number 19498 is also a useful search term for buyers looking for an OE-style molded coolant hose with the correct 0.66-inch ends and 12.7-inch centerline length.

What This Hose Helps Address

• Coolant leaks from cracked or deteriorated heater hose material
• Poor hose routing caused by a straight hose in a molded application
• Restricted heater circuit flow from a collapsed or softened hose
• Fitment issues in compact engine compartments
• Replacement needs for aging OEM-style molded coolant hoses

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. Confirm the vehicle application against the fitment list for Honda Accord, Honda Civic, Honda CR-V, Honda Element, Acura TSX, Acura ILX, and Honda Crosstour. Inspect adjoining heater pipes, clamps, and connection points for wear or corrosion before installing Gates 19498.
