Gates HVAC Heater Hose P/N:18774
Gates 12466 heater hose for the 2017-2018 Hyundai Ioniq carries hot coolant as part of the heating system. It is an OEM-style hose that works for coolant, water and air applications and is also approved for marine use.
Cracks, a swollen or soft section or coolant dampness along the hose can mean it is wearing out. Before you replace the hose, rule out a loose clamp or a leaking fitting at either end, since the coolant could be coming from there. Do not use it for fuel or oil transfer.
This Gates molded heater hose fits the 2017-2018 Hyundai Ioniq.
