Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the negative battery terminal for safety.

2. Coolant Level Check

Remove the radiator cap (ensure engine is cool to avoid burns).
Check coolant level; if low, top off with a 50/50 mix of coolant and distilled water.

3. Thermostat Replacement

Drain the coolant from the radiator until it is at a safe level.
Remove the thermostat housing bolts using a socket wrench.
Take out the old thermostat and clean the mating surfaces.
Install the new thermostat (ensure proper orientation).
Reattach the thermostat housing and torque the bolts to manufacturer specifications.

4. Water Pump Inspection/Replacement

If the water pump is suspected to be faulty, drain the coolant as in the previous step.
Disconnect any hoses connected to the water pump.
Remove the water pump by unbolting it from the engine block.
Clean the mounting surface on the engine.
Install the new water pump and torque to manufacturer specifications.

5. Radiator and Cooling Fan Check

Ensure the radiator is free from debris and blockages; clean as necessary.
Test the cooling fans by turning on the engine and observing if they engage when the engine reaches operating temperature.
Replace any faulty fans or relays as needed.
