Gates Molded Heater Hose for Tesla S
Gates 12483 is a molded heater hose built for tight engine and coolant routing spaces where a straight hose will not follow the factory path. It uses EPDM construction and an OEM-style molded shape to support coolant, water, and air transfer in the 2012-2016 Tesla S.
Key Features
- Factory-molded hose profile for compact routing
- EPDM material for coolant-system service
- Small I.D. design with 25 mm (0.969 in.) end 1 and 18.5 mm (0.728 in.) end 2
- 24 in. (610 mm) centerline length
- Approved for marine applications
- Gates part number 12483
Product Details
This Gates Molded Heater Hose is part of the Gates Molded Heater Hose line, which focuses on OEM-style hose shapes for modern vehicles with tighter packaging around the engine bay. Gates 12483 is formed to follow the original routing more closely than universal hose, helping maintain proper hose alignment in coolant and heater circuits. It is a direct fit for 2012-2016 Tesla S, N/A, and the molded profile supports clean installation in confined spaces. This part cross-references Bosch 13483 for the same application.
Common Problems It Can Address
- Cracked or aged heater hose material
- Improper hose routing from a previous repair
- Coolant seepage at a worn hose section
- Fitment issues caused by a non-molded replacement hose
- Service replacement for a damaged Tesla S heater hose
Installation Notes and Tips
Verify end diameters and centerline length against the original hose before installation. Route the hose to match the factory path and inspect adjoining clamps, fittings, and coolant connections for wear or contamination. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
Quality Assurance
Gates manufactures this molded coolant hose as an OEM-style replacement for vehicles that require precise hose shaping and reliable EPDM construction. It is suitable for coolant, water, and air applications, with marine application approval noted by the manufacturer.
