The heater hose and coolant hose are two of the most vital hoses in the car cooling system. Do you need to change them? Or are you only curious about their differences? Whatever the reason is, a comparison in heater hose vs coolant hose will definitely enhance your knowledge.
The key difference is the working processes. When your car’s engine is active, it heats too much. A coolant hose transfers a coolant mixture that absorbs the heat to keep the engine cool. Then a heater hose releases excess heat to the open air and cycles the coolant liquid back to the engine.
A detailed comparison between these two hoses can be more helpful to understand the processes. We have explained the differences in this article and also provided solutions to some common problems regarding coolant and heater hoses.

Heater Hose vs Coolant Hose: Key Differences
The heater hose and coolant hose are more or less the same. But they have some minor differences.
The major differences between heater hoses and coolant hoses are:
The working process starts with the coolant hose. It includes water and coolant fluid such as Freon. The liquid mixture stays in a state where it can absorb the heat that the engine of your car produces. A part of the excess heat is released to the open air, while the rest of the heat goes to the heater core to retain the coolant.
This is where the heater hose comes into play. The heater hose transfers the excess heat to the heater core. There a fan blows the heat to send the hot air into the cabin. Then the coolant is cycled back to the engine to keep it running.
The application of coolant hose and heater hose have different purposes. When your engine is active, it produces too much heat that can blow out the engine. The purpose of the coolant hose is to transfer out the heat so that the engine can work fine.
And the purpose of the heater hose is to provide hot air into the cabin and retain coolant that helps the coolant hose to keep the engine at a normal temperature.
The recommended period for replacing the heater hose and coolant hose is 4 to 5 years. If you believe your hoses are damaged earlier, you can replace them. However, the cost for real replacing hoses can be around 50 to 500 dollars. Heater hoses usually cost less than coolant hoses.
