Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery (negative terminal) to prevent electrical issues.

2. Drain Old Coolant

Tools Required: Drain pan, socket set
Place the drain pan under the radiator.
Locate the radiator drain valve at the bottom of the radiator and open it to let the old coolant drain completely.
Close the drain valve once drained.

3. Flush the Radiator

Tools Required: Garden hose, funnel
Using a garden hose, insert it into the radiator filler neck.
Turn on the hose and let water flow through the radiator until it runs clear from the drain valve.
Alternate between filling and draining to ensure all old coolant and debris are removed.

4. Inspect and Replace Components

Tools Required: Socket set, pliers
Inspect hoses for wear and replace if necessary.
Check the radiator cap for proper sealing and replace if damaged.

5. Refill with New Coolant

Parts Required: New coolant (check manufacturer specifications for type and mixture)
Using a funnel, refill the radiator with a 50/50 mixture of coolant and distilled water.
Top off the coolant reservoir to the appropriate level.

6. Bleed the Cooling System

Tools Required: None specific, but a funnel may help
Start the engine and allow it to reach operating temperature.
Turn the heater to the maximum setting to allow air to escape.
Monitor the coolant level and add more if necessary until no air bubbles are present.

7. Final Check

Inspect for leaks around the radiator and hoses.
Reconnect the battery.
