Detailed Description

Rein CHH0827 is engineered to match the original heater hose assembly used on Tesla S models, including 2012-2015 Tesla S and 2016 Tesla S built through 3/31/16 with OE No. 103729600E. The hose follows OE size and shape requirements so it installs in the same routing and connection points as the factory part. This part cross-references OE No. 103729600E for the same application.

What This Heater Hose Helps Address

• Coolant transfer issues caused by a cracked or aged heater hose
• Leaks at worn hose connections or quick-connect interfaces
• Loss of heater performance from restricted or damaged hose flow
• Service replacement needs after hose deterioration in Tesla S HVAC systems

Installation Notes and Tips

Verify OE No. 103729600E and confirm the vehicle build date before ordering, since 2016 Tesla S coverage applies only to vehicles built through 3/31/16. Match the hose routing, end diameters, and quick-connect style to the original assembly before installation. Inspect mating surfaces and replace any worn clamps or seals as needed during service.

Quality Assurance

Rein Automotive positions this heater hose as an OE-quality replacement built to follow original manufacturer dimensions and connection design for Tesla S service work.
