how can I tell if my Honda Accord's radiator is clogged

Solution

1. Preparation

• Gather the necessary tools and parts.
• Ensure the engine is cool and disconnect the battery to prevent electrical issues.
• Tools Required: Socket set, pliers, coolant flush kit, pressure tester.

2. Drain the Radiator

• Locate the radiator drain plug at the bottom of the radiator.
• Place a drain pan underneath and open the drain plug to let coolant flow out.
• Close the drain plug once the radiator is empty.

3. Flush the Radiator

• Attach a garden hose to the top radiator hose or use a coolant flush kit.
• Turn on the water and let it flow through the radiator until clear water runs out of the drain.
• If using a flush kit, follow the manufacturer’s instructions for flushing agents.
• Close the drain plug after flushing.

4. Refill the Cooling System

• Mix the appropriate coolant (usually a 50/50 mix of antifreeze and distilled water).
• Slowly refill the radiator and reservoir with the new coolant.
• Run the engine with the radiator cap off to allow air to escape and ensure the system is bled of air.

5. Test the System

• Reconnect the battery.
• Start the engine and allow it to reach operating temperature.
• Monitor the temperature gauge and check for leaks around the radiator and hoses.
