Repair Instructions

Step 1: Prepare for Repair

Ensure the engine is cool and the vehicle is parked on a level surface.
Gather all necessary tools and materials.

Step 2: Replace Leaking Hose or Clamp

Identify the leaking hose or clamp.
Use pliers to loosen the hose clamp and remove the hose.
Install the new hose or clamp, ensuring it fits securely.
Reattach the hose clamp and tighten it with pliers.

Step 3: Repair or Replace the Radiator

If the radiator is leaking:
- Remove any front-end components obstructing access to the radiator (if necessary).
- Disconnect the upper and lower radiator hoses.
- Remove any screws or bolts securing the radiator in place.
- Lift out the radiator and replace it with a new one.
- Reconnect hoses and secure the radiator.

Step 4: Address Internal Leaks

If combustion gases are detected:
- This typically indicates a blown head gasket.
- You will need to disassemble the engine, replace the head gasket, and reassemble. This is a complex procedure that may require professional assistance.

Step 5: Refill Coolant

After repairs, refill the cooling system:
- Use a funnel to pour the correct type of coolant into the radiator or reservoir.
- Start the engine and allow it to reach operating temperature. This will help bleed air from the system.
- Check for leaks and ensure the coolant level remains stable after the engine cools.

Step 6: Final Checks

Monitor the coolant levels over the next few days and inspect for any signs of leaks.
Keep an eye on the engine temperature gauge during normal operation.
