Step-by-Step Instructions
1. Locate the Heater Hoses
Open the hood and locate the two heater hoses connected to the engine. One hose is usually larger and carries hot coolant, while the other is smaller and returns cold coolant.
2. Drain the Coolant
Place a drain pan under the radiator and loosen the drain plug on the bottom of the radiator. Allow the coolant to drain into the pan.
3. Disconnect the Battery
Locate the negative battery terminal and disconnect it using a wrench. This will prevent electrical shocks and damage to the vehicle’s electronics.
4. Remove the Air Intake
Unclip the air intake hose from the throttle body and remove it to provide access to the heater hoses.
5. Disconnect the Heater Hoses
Using pliers, gently squeeze the hose clamps on the heater hoses and slide them back. Pull the hoses off the engine connections.
6. Remove the Hose Clamps
Using a screwdriver, remove the hose clamps from the heater hoses.
7. Install the New Heater Hose
Slide the new heater hose onto the engine connections and secure it with the hose clamps. Tighten the clamps firmly but avoid overtightening.
8. Reconnect the Battery
Reconnect the negative battery terminal to the battery.
9. Refill the Coolant
Pour the drained coolant back into the radiator and add new coolant if necessary. Check the coolant level and top it off as needed.
10. Start the Engine and Check for Leaks
Start the engine and allow it to run for a few minutes. Check for any leaks around the heater hoses. If no leaks are present, turn off the engine and allow it to cool down.
11. Reinstall the Air Intake
Reconnect the air intake hose to the throttle body and clip it into place.
Tips for Success
