Function 1:
Connect the engine cooling system with the small water tank inside the vehicle, and transfer the hot coolant generated during engine operation to the small water tank for heating

Function 2
When the original factory hose becomes aged, cracked, or hardened, causing coolant leakage or insufficient flow, this kit can be directly replaced to restore the normal operation of the heating system

Package includes:
2 x Heater hose line (as shown in pictures)

Note:
Before installation, make sure the engine is completely cooled down (it is recommended to turn off the engine and let it rest for 1-2 hours). Also, empty the coolant from the cooling system in advance
Within 1-2 weeks after the first use after installation, it is necessary to regularly check for coolant leakage at the hose connection (look for wet marks or white crystals near the interface), and check if there are any abnormal bulges on the surface of the hose.
