Key Features
- Direct replacement HVAC heater hose for Tesla S
- EPDM construction for heat and coolant exposure resistance
- Black finish for an OE-style appearance
- Includes clamps
- End 1 inside diameter: 18.80 mm
- End 2 inside diameter: 18.80 mm
- End 1 outside diameter: 25.83 mm
- End 2 outside diameter: 25.83 mm
Detailed Description
Rein CHH0834 is an HVAC heater hose engineered as a direct OE replacement for Tesla S models equipped with OE part number 103785700A. Rein builds this hose to mirror the original hose assembly, including branch geometry and quick-connect fitment details, so it installs in the same location and follows the factory routing. This part cross-references OE number 103785700A for the same application.
Compatible With 2012-2015 Tesla S, N/A. Compatible With 2016 Tesla S, N/A, to 3/31/16. The Rein CHH0834 heater hose is a practical service part for restoring coolant flow through the HVAC system on these Tesla S model years.
What It Helps Resolve
- Coolant seepage from a worn heater hose
- Cracked or hardened EPDM hose material
- Damaged quick-connect ends or hose branches
- Loss of heater performance from restricted coolant circulation
- Service replacement for OE hose assembly 103785700A
Installation Notes and Tips
Verify OE number 103785700A before installation and confirm the vehicle build date for 2016 Tesla S applications through 3/31/16. Inspect mating connections, routing points, and adjacent hoses for wear before reassembly. Use the included clamps during installation and ensure all connections are fully seated and leak-free after refill and bleed procedures.
Quality Assurance
Rein Automotive focuses on OE-quality replacement parts that follow original equipment dimensions and connection design. CHH0834 is built to match the factory hose assembly for consistent fit and serviceability on the specified Tesla S applications.
