12-Pc. Coolant Refilling Funnel Set with Extension Pipes

Changing the coolant in your vehicle and properly bleeding the air from the system is important to ensure the engine runs at the correct temperature and to avoid air pockets that can cause overheating. Here’s a step-by-step guide for changing the coolant with the air bleeding method:

Materials Needed:
- New coolant (refer to your vehicle’s owner’s manual for the correct type and amount)
- Distilled water (if you need to mix the coolant)
- Drain pan
- Socket set and wrenches
- Screwdrivers
- Funnel
- Clean rags or shop towels
- Safety glasses and gloves

Step-by-Step Guide:

1. Preparation:
   - Park the Vehicle: Ensure the vehicle is on a flat, level surface. Engage the parking brake.
   - Cool Down: Make sure the engine is completely cool before starting the process to avoid burns from hot coolant.

2. Drain the Old Coolant:
   - Locate the Radiator Drain Plug: Refer to your vehicle’s manual to find the drain plug on the radiator.
   - Place the Drain Pan: Position a drain pan underneath the drain plug.
   - Open the Drain Plug: Remove the drain plug and allow the old coolant to drain out completely. You may also need to remove the radiator cap to allow for faster draining.
   - Drain the Engine Block: Some vehicles have a drain plug on the engine block. Remove this plug to ensure all the old coolant is drained.

3. Flush the Cooling System (Optional but Recommended):
   - Flush with Water**: Reinstall the drain plugs and fill the cooling system with distilled water. Run the engine with the heater on high until it reaches operating temperature, then allow it to cool and drain the water.
   - Repeat if Necessary**: Repeat the flushing process until the water drains clear.

4. Refill with New Coolant:
   - Close Drain Plugs: Ensure all drain plugs are securely reinstalled.
   - Mix Coolant: If you are using concentrated coolant, mix it with distilled water according to the manufacturer’s instructions.
   - Fill the Radiator: Slowly fill the radiator with the new coolant until it reaches the top. Fill the overflow tank to the appropriate level as well.

5. Bleed Air from the System:
   - Locate the Bleed Screws: Some vehicles have bleed screws on the thermostat housing or near the top of the radiator. Consult your vehicle’s manual.
   - Open the Bleed Screws: Open the bleed screws slightly to allow air to escape. Continue filling the radiator with coolant as the air is bled out.
   - Run the Engine: Start the engine and let it idle. Turn the heater on to the maximum temperature setting. Watch the coolant level and add more as it drops. Air bubbles should escape through the bleed screws.
   - Check for Air Pockets: Squeeze the upper radiator hose periodically to help dislodge air pockets. Keep an eye on the temperature gauge to ensure the engine does not overheat.

6. Close the System:
   - Close the Bleed Screws: Once a steady stream of coolant flows from the bleed screws with no air bubbles, close them securely.
   - Replace the Radiator Cap: Ensure the radiator is full and replace the radiator cap securely.

7. Check the Coolant Level:
   - Monitor Levels: Over the next few days, check the coolant level in the overflow tank and top off if necessary. Ensure there are no leaks and the system is functioning properly.

8. Dispose of Old Coolant Properly:
   - Proper Disposal: Take the old coolant to a recycling center or an automotive store that accepts used coolant. Do not pour it down the drain or onto the ground.

Tips and Warnings:
- Safety First: Always wear safety glasses and gloves when handling coolant.
- Correct Coolant: Use the type of coolant specified in your vehicle’s owner’s manual.
- Avoid Overfilling: Do not overfill the radiator or overflow tank.
- Regular Maintenance: Change the coolant according to your vehicle manufacturer’s recommended interval to maintain optimal engine performance and cooling efficiency.

Properly bleeding the air from the cooling system ensures there are no air pockets that can cause overheating and engine damage. If you are unsure about any step, consult a professional mechanic.
