Product Details and Specifications

This HVAC heater hose features a molded construction that maintains consistent dimensions throughout its 16.7-inch (424 mm) centerline length. Both ends have an inside diameter of 0.75 inches (19 mm), ensuring compatibility with factory fittings. The EPDM material provides resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity under typical engine compartment conditions. The absence of quick connect fittings and branches simplifies installation and reduces potential failure points.

Common Applications and Problem Solving

• Replacement of worn or cracked heater hoses in Ford Thunderbird and Lincoln LS HVAC systems
• Repair of coolant leaks causing insufficient cabin heating in Jaguar S-Type vehicles
• Restoration of proper coolant flow in Nissan 240SX heater core connections
• Addressing hose swelling or softening due to heat exposure
• Eliminating coolant odor or puddling inside the vehicle caused by hose failure

Installation Notes and Tips

Ensure the engine is cool before beginning installation to avoid burns from hot coolant. Verify hose routing matches the original configuration to prevent kinks or interference with other components. Use appropriate clamps to secure the hose ends firmly without over-tightening, which can damage the hose. Inspect adjacent components for wear or damage during replacement to maintain overall HVAC system integrity.
