Heater Core Hoses Replacement

Mobile Heater Core Hoses Replacement at Home or Office

Made of durable rubber, heater hoses are built to sustain the hot coolant that is carried from the engine to the heater core. Poor climate control is a sign of problems with your vehicle's hoses. When your heater hoses near the end of their useful life, they will become hard and brittle or soft and mushy. If they crack, the coolant will leak and pool underneath your vehicle. When this happens, allow a mobile mechanic of Wrench service staff to replace your heater core hoses. A leaky hose means your heating system will not effectively heat your vehicle, and your cooling system will not have a proper supply of coolant. Leaky heater hoses can result in your engine overheating. As such, we encourage you to periodically inspect your heater hoses to determine the correct time to replace them.

What is Heater Core Hoses Replacement?

Heater hoses play a crucial role in a vehicle's heating system, which operates in conjunction with the cooling system. Heater hoses are integral to your engine's cooling system. They are comprised of the soft, pliable rubber material, each hose has a different function. Radiator hoses are connected to both the radiator and engine to direct coolant to the radiator so it can be cooled and then back into the engine so it can maintain a certain temperature, preventing overheating. Heater hoses are used to transfer heated coolant into the vehicle's heating unit or heater core. Heater hoses are responsible for carrying coolant to prevent overheating. More specifically, heater hoses are responsible for transferring coolant away from the engine to the heater core, where the warm air can be blown into the compartment of your vehicle by engaging the adjacent fan. Heater fans blow through the heater core to heat the vehicle and cool the antifreeze inside of it. The hoses transfer the coolant back into the path of the cooling system at a lower temperature so the coolant can continue to regulate consistent temperatures inside the engine.

How is Heater Core Hoses Replacement Done?

1. Locate the heater hoses to be replaced and remove or relocate any obstructions.
2. Some vehicles use a spring loaded hose clamp which can be removed by using a special hose clamp removal tool, a pair of pliers can also be used.
3. Once the tool has been installed, move the hose clamp to gain access to the hose mounting fitting.
4. After the hose clamps have been loosened and relocated down the hose, use an exacto knife or razor blade to gently slice the hose long ways along the fitting.
5. Once the heater hose has been cut, gently lift and twist the hose to release it from the heater core fitting, repeat this process for the remaining hose.
6. Locate and remove the heater hoses from the engine which are usually near the engine water pump.
7. After the hoses have been released from the heater core and engine, remove any remaining mounting hardware and remove the hoses from the engine bay.
8. It can take a little ingenuity to configure the hoses for removal.
9. Once the heater hoses have been removed, use a shop towel to clean the heater hose fittings to help seal the new hose installation.
10. Compare the worn heater hose set to the replacement hoses to ensure a proper installation.
11. After comparing the new hose set, install the hoses into the engine bay.
12. Once the heater hoses have been placed into the engine bay, connect the hoses to the engine using new hose clamps.
13. Position the hose clamp over the middle of the hose fitting and tighten securely, repeat this process for the remaining hose.
14. After the hoses are installed and clamps tightened, inspect for obstructions such as metal shielding that can damage the hose and relocate to prevent damage to the hose.
15. Connect the remaining hose ends onto the heater core fittings using a hose clamp tool to activate the clamp.
16. It helps to activate the clamp tool before attaching the hose to the fitting.
17. Once the heater hose connections are complete, refill the cooling system.
