Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the engine is cool and disconnect the battery to prevent electrical issues.
Tools Required: Socket set, screwdrivers, coolant pressure tester, UV dye kit (if needed), and safety glasses.

2. Identify the Leak Source

Sub-steps:
1. If visible damage is found on hoses or connections, proceed to replace those components.
2. If the radiator shows signs of leaking, remove it for replacement.

3. Replace Damaged Hoses

Sub-steps:
1. Loosen the hose clamps using a screwdriver or socket.
2. Remove the damaged hose and discard it.
3. Install the new hose, ensuring it fits securely.
4. Reattach the hose clamps and tighten them to the manufacturer's specifications (usually around 15-25 in-lbs).

4. Replace Radiator (if necessary)

Sub-steps:
1. Drain coolant from the radiator using the drain valve at the bottom.
2. Disconnect the upper and lower radiator hoses, transmission cooler lines (if applicable), and any electrical connections.
3. Remove the mounting bolts and lift the radiator out of the vehicle.
4. Install the new radiator in reverse order of removal, ensuring all connections are secure.
5. Refill the cooling system with the appropriate type of coolant (refer to the owner's manual for specifications).

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle while checking for leaks.
3. Monitor the coolant level and top off as needed.
