Solution

1. Preparation

Tools Required: Cooling system pressure tester, funnel, coolant, rags, safety glasses, gloves.
Ensure the engine is cool before starting work to avoid burns.

2. Perform a Pressure Test

Sub-steps:
1. Remove the radiator cap (ensure the engine is cool).
2. Attach the cooling system pressure tester to the radiator neck or overflow tank.
3. Pump the tester to the recommended pressure (usually around 15-20 psi).
4. Observe the system for any signs of coolant leaking from hoses, the radiator, or the engine.

3. Repair Identified Leaks

Sub-steps:
1. If a leak is found in a hose, loosen the clamps and replace the hose.
2. If the radiator is leaking, drain the coolant, remove the radiator, and replace it.
3. For a leaking water pump, drain the coolant, remove the pump, install a new pump with a new gasket, and refill the coolant system.
4. If internal leaks are suspected, further diagnostics may be needed for head gasket replacement.

4. Refill Coolant

Sub-steps:
1. Use a funnel to refill the coolant through the radiator or overflow tank.
2. Ensure to use the correct type of coolant as specified in the owner's manual.
3. Start the engine and let it run to allow the coolant to circulate, checking for leaks again.
