What Is a Heater Hose?

A heater hose in a car is responsible for helping carry engine coolant from one point to another, particularly the engine and the heater core. This process helps supply heat to the passengers inside the cabin and ensures that the inside of the vehicle is kept warm.

How Much Does a Heater Hose Replacement Cost?

The cost of a heater hose replacement ranges from as low as $5 to as high as $400 for parts. Factors that affect the cost of the part include the hose material, the type of hose, and the length of the hose based on the configuration of hoses in your vehicle. The cost of labor, on the other hand, ranges from $100 to $150.
