Gates Molded Heater Hose for Tesla S
The Gates 12484 molded heater hose is an OEM-style coolant hose shaped for tight engine-compartment routing. It is built from EPDM and sized with 18 mm inside diameters at both ends for a precise connection in the Tesla S 3-way valve to chiller location.
Key Features
- Factory-molded design for compact routing in smaller engine spaces
- EPDM construction for coolant, water, and air service
- 18 mm inside diameter at both ends
- 12.25 in. centerline length for the specified routing path
- Approved for marine applications
- Gates Molded Heater Hose line for OE-style replacement fitment
Detailed Description
Gates part number 12484 is a molded heater hose made to follow the original hose path used on 2012-2016 Tesla S models at the 3-way valve to chiller position. The molded shape helps maintain proper routing where space is limited, while the EPDM material is suited for coolant transfer and related fluid or air applications. If you are replacing a worn Tesla S heater hose, 12484 provides the correct molded configuration for this application. This part cross-references SKF 13484 for the same application.
Common Issues This Hose Can Address
- Coolant seepage from an aged or hardened hose
- Cracking or splitting caused by heat cycling
- Poor hose routing in a tight Tesla S cooling circuit
- Fitment problems from using a straight hose where a molded hose is required
- Service replacement for the 3-way valve to chiller hose path
Installation Notes and Tips
Verify the hose routing against the original Tesla S layout before installation. Confirm the end diameters and centerline length match the removed hose, and inspect adjoining fittings, clamps, and sealing surfaces for wear or contamination. Proper alignment is important on molded hoses to avoid twist or stress at the connection points.
Quality Assurance
Gates manufactures molded coolant hoses to OE-style dimensions and routing requirements for modern vehicle cooling systems. Part number 12484 is built for the specified Tesla S application and the brand’s molded heater hose product line.
