Gates 19845 HVAC Heater Hose - Tee To Reservoir or Thermostat To Reservoir

Gates Molded Heater Hose 19845 Overview

Product Line Details

The Gates Molded Heater Hose line is made for vehicles that need a formed hose path rather than a universal straight replacement. Gates 19845 follows the original routing used in smaller, tighter-fitting engine compartments, helping maintain proper hose alignment in heater and coolant circuits.

What This Hose Helps Address

• Cracked or leaking heater hose routing in the coolant circuit
• Collapsed or softened hose sections from heat and age
• Poor fitment from a hose that does not match the factory bend
• Restricted coolant flow caused by a damaged molded hose
• Replacement needs for thermostat-to-reservoir or tee-to-reservoir routing

Installation Notes

Verify the hose path, end diameters, and centerline length before installation. This molded hose is shaped for specific routing on Chevrolet Malibu, Pontiac G6, and Saturn Aura applications, so confirm whether your vehicle uses the thermostat-to-reservoir or tee-to-reservoir position. Inspect adjoining fittings and clamps for wear before installing the new hose.
