About Heater Hose

The heater hose is in control of carrying the engine coolant from one point to another. The procedure helps supply heat to the passengers and makes sure that the vehicle is kept warm.

Heater hose concept

Heater hoses make hot coolant travel from the cylinder head to the heater core of the vehicle. Especially, during the cold winter months, the heating system must be working correctly.

Some of the heat from the engine goes to the radiator and into the heater core. The heated engine coolant travels through the small tubes until it reaches the heater core. The connectors also play a part in holding the heater hoses since the heat causes the hoses to expand and shrink.

Common issues with a heater hose

A bad heater hose can lead to coolant leaks, engine overheating, and hose hardening can occur.
