Continental 64283 HVAC Heater Hose

Continental 64283 Heater Hose for Toyota

Continental 64283 is a molded HVAC heater hose built for coolant transfer between the heater core, radiator bypass circuits, and related engine cooling components. With a 0.690 in. inside diameter at both ends and a 13.400 in. molded length, it matches the routing needs found on select Toyota Tacoma and Toyota 4Runner applications.

Continental Molded hose construction follows SAE 20R3EC Class D1 and Class D2 requirements and is formulated to resist electrochemical degradation, helping maintain coolant flow in demanding heater hose service.

Key Features

• Part number 64283 molded HVAC heater hose
• 0.690 in. inside diameter at both ends
• 13.400 in. molded hose length
• Built for glycol-based coolant transfer
• Meets SAE 20R3EC Class D1 and Class D2 specifications
• Resistant to electrochemical degradation (ECR)
• Continental Molded product line for formed hose routing

Detailed Description

This Continental heater hose is engineered for direct coolant routing in HVAC and engine cooling systems, moving glycol-based coolant to and from the heater core, through bypass passages, and across other connected components. The molded shape supports the factory-style routing used on Toyota Tacoma and Toyota 4Runner heater hose applications, including heater-to-pipe and tee-to-pipe positions. Part number 64283 is a practical replacement when the original hose has hardened, cracked, or lost its formed shape.

This part cross-references Carlson 19130 for the same application.

What It Helps Solve

• Coolant leaks from a cracked or aged heater hose
• Restricted heater flow caused by hose collapse or internal deterioration
• Loss of factory routing on molded Toyota Tacoma and Toyota 4Runner heater hose runs
• Service issues related to electrochemical degradation in the cooling system
• Improper fit from a straight hose where a molded hose is required

Installation Notes and Tips

Verify hose routing, inside diameter, and molded length against the removed part before installation. Compatible With 2000-2004 Toyota Tacoma, Heater To Pipe-1; 1995-2002 Toyota Tacoma, Heater To Pipe-2; 1996-2002 Toyota 4Runner, Heater To Pipe-4; 2002 Toyota 4Runner, Tee-2 To Pipe-1, w/Aux Htr; and 1996-2001 Toyota 4Runner, Pipe-1 To Tee-2, w/Aux htr. Confirm clamp condition and inspect adjoining pipes and heater core connections for wear or corrosion during service.

Quality Assurance

Continental Molded heater hoses are built to meet SAE 20R3EC Class D1 and Class D2 specifications and include resistance to electrochemical degradation for durable coolant-system service. Part number 64283 is manufactured for the listed Toyota Tacoma and Toyota 4Runner applications.
