Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool and the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical issues.

2. Identify and Repair Leaks

Hoses and Connections:
- If a hose is damaged, use a hose clamp tool to remove the affected hose.
- Replace with a new hose matching OEM specifications.
- Reattach using hose clamps and ensure a tight fit.
Water Pump Replacement:
- Remove the drive belt using a socket set.
- Unscrew the water pump bolts and remove the old pump.
- Clean the mounting surface on the engine.
- Install the new water pump with a new gasket, torque bolts to manufacturer specifications.
- Reattach the drive belt.
Head Gasket Repair:
- If coolant is leaking from the head gasket, it requires more extensive work.
- Remove intake and exhaust manifolds.
- Unbolt the cylinder head and replace the gasket.
- Reassemble all components, ensuring proper torque values are followed.

3. Refill Coolant

After repairs, refill the cooling system with the appropriate coolant (Toyota Long Life coolant or equivalent).
Bleed the system of air by running the engine with the radiator cap off until the thermostat opens.
