Preparation:
1. Park the car in a well-ventilated area and allow the engine to cool down completely.
2. Gather the necessary tools, including a new heater hose, coolant, pliers, a screwdriver, and a bucket to collect the draining coolant.
Steps:
1. Locate the Heater Hose:
- Open the hood of your Matiz.
- The heater hose is typically located on the passenger side of the engine compartment. It connects the engine to the heater core inside the car.
2. Drain the Coolant:
- Place the bucket under the radiator drain plug, which is usually located at the bottom of the radiator.
- Open the drain plug to drain the coolant from the system. Allow the coolant to drain completely.
3. Disconnect the Heater Hose:
- Use the pliers to loosen the hose clamps at both ends of the old heater hose.
- Carefully remove the old hose by gently pulling it off the connections.
4. Install the New Heater Hose:
- Align the new heater hose with the connections and slide it onto the heater core and engine nipples.
- Secure the hose by tightening the hose clamps with the pliers.
5. Refill the Coolant:
- Close the radiator drain plug.
- Open the coolant reservoir cap (usually marked "Coolant" or "Radiator").
- Slowly pour the coolant into the reservoir until the level reaches the "MAX" mark.
- Replace the reservoir cap.
6. Start the Engine:
- Start the engine and let it run for a few minutes to circulate the coolant through the system.
- Check for any leaks around the new hose connections. If there are any leaks, tighten the hose clamps further.
7. Check the Coolant Level:
- After the engine has cooled down, recheck the coolant level in the reservoir. If necessary, add more coolant to bring it back to the "MAX" mark.
Note:
If the coolant appears discolored or contaminated, it's recommended to perform a complete coolant flush to clean the entire cooling system.
Remember to follow proper safety precautions when working with hot coolant and always allow the engine to cool down before attempting any repairs.
