Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cold to prevent burns.
Disconnect the negative battery terminal.

2. Locate and Repair the Leak

Coolant Reservoir
- Remove the reservoir by disconnecting any clamps and hoses.
- Inspect for cracks; if damaged, replace the reservoir.
Hoses
- Remove any damaged hoses by loosening the clamps and sliding them off.
- Replace with new hoses; ensure they are secured tightly with clamps.
Radiator
- Inspect the radiator for cracks or damage; if leaking, remove the radiator by disconnecting the upper and lower hoses, and the mounting brackets.
- Replace with a new radiator if necessary.
Water Pump
- If the water pump is leaking, remove the serpentine belt and unbolt the pump.
- Replace the water pump with a new one, ensuring a new gasket is in place.
- Reinstall the serpentine belt.

3. Refill and Bleed the Cooling System

After repairs, refill the cooling system with the appropriate coolant mixture (50/50 coolant and distilled water).
Bleed the cooling system to remove air pockets by running the engine with the radiator cap off until the thermostat opens and coolant circulates.
