Replacement Heater Hose Assemblies
Heater hoses help transfer coolant from the engine or water pump to the heater core and back, helping circulate warm coolant used to heat your vehicle's interior. Made of either plastic or rubber, heater hoses carry coolant to and from your engine, helping regulate the temperature of your engine as well as supply hot air to the cabin as needed. Original heater hoses on many modern vehicles may be molded to fit around parts of the engine and feature quick-connect fittings that require special tools to remove, but older vehicles may simply use cut-to-length rubber heater hose and hose clamps to make these connections. One heater hose moves coolant between the water outlet or water pump to the heater core, and the blower motor moves air over the fins of the heater core to increase its temperature before it passes through the vents and into the cabin. After the coolant has passed through the heater core, a second heater hose transfers antifreeze back to the engine to repeat the cycle. These hoses are a critical part of a vehicle's heating system, and clogged heater hoses can in some cases lead to https://www.oreillyauto.com/how-to-hub/overheating-issues, engine damage, or poor interior heater performance. Although they are designed to withstand high temperatures, your car's heater hose may fail, crack, split, or become brittle over time, increasing the chance of a coolant leak. Signs of a bad heater hose include coolant leaks, low coolant levels, a lack of hot air from the vents, steam coming from under the hood or the smell of coolant through the vents, and the hose may feel brittle, spongy, or have visible cracks. If you notice these symptoms, be sure to inspect your heater hoses, their connectors, and the heater core inlet and outlet for signs of leaking, damage, or other problems. Some vehicles may have a heater valve that controls the flow of coolant to or from the heater core, so be sure to understand your vehicle's heating system and components before inspection.
