Continental 64134 HVAC Heater Hose

Continental HVAC Heater Hose 64134

Continental 64134 is a molded HVAC heater hose built for coolant transfer between the heater core, bypass circuit, radiator, and related engine cooling components. It is formed to match the routing used on select Honda and Acura applications, with a 0.620 in. inside diameter at both ends and a 13.470 in. hose length.

Continental’s Molded line focuses on OE-style hose routing and fitment for service replacements where a formed hose is required. This heater hose is specified to SAE 20R3EC Class D1 and Class D2 standards and is resistant to electrochemical degradation (ECR), helping it stand up to coolant exposure in demanding HVAC and cooling-system service.

Installation Notes and Tips

Verify hose routing, end diameters, and molded shape against the original hose before installation. Inspect adjoining heater valves, tees, pipes, and clamps for wear or corrosion, and replace any damaged cooling-system components before refilling with coolant. Confirm the hose is seated fully on each connection point and check for leaks after the engine reaches operating temperature.
