Solution

1. Preparation

Tools Required: Safety goggles, gloves, pressure tester, UV dye kit (if needed), flashlight, and basic hand tools (screwdrivers, wrenches).
Safety Warnings: Allow the engine to cool before working on the cooling system. Wear gloves and goggles to protect from hot coolant.

2. Repair the Leak

Identify the Leak Source: Based on the diagnostics, focus on the identified leak area (e.g., hose, radiator, water pump).
Replace Damaged Hoses:
1. Use a wrench to loosen hose clamps.
2. Remove the damaged hose and discard it.
3. Install the new hose and secure it with clamps, ensuring they are tight (torque to manufacturer's specification).
Repair or Replace Radiator:
1. Drain the coolant from the radiator.
2. Disconnect the upper and lower radiator hoses.
3. Remove any mounting bolts and lift the radiator out.
4. Install the new radiator and reconnect hoses, ensuring proper fit and sealing.
Fix Leaky Water Pump:
1. Drain the coolant.
2. Remove the drive belt and any components obstructing access to the water pump.
3. Unbolt the water pump from the engine and remove it.
4. Clean the mounting surface, install a new gasket, and bolt the new water pump in place.
5. Reassemble the components and refill coolant.
