Solution

1. Preparation

Gather necessary tools and parts.
Make sure the engine is cool before beginning work.
Disconnect the battery to prevent electrical issues.

2. Coolant System Inspection

Remove the engine cover if applicable.
Inspect the coolant reservoir for proper level; refill as necessary with the correct coolant type (Volvo-approved).
Check the radiator cap for proper sealing and replace if damaged.

3. Thermostat Replacement

Drain the coolant from the radiator into a clean container.
Remove the thermostat housing bolts using a socket set.
Carefully lift the thermostat out and replace it with a new unit, ensuring correct orientation.
Reattach the thermostat housing and torque bolts to manufacturer specifications (check owner's manual for torque value).

4. Water Pump Replacement (if needed)

Drain the remaining coolant.
Disconnect hoses from the water pump and remove bolts securing the pump.
Carefully remove the old water pump and clean the mating surface.
Install the new water pump and torque bolts to specifications.
Reconnect hoses and refill the cooling system with the appropriate coolant.

5. Cooling Fan Test

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature and observe if the cooling fan activates appropriately.
If the fan does not engage, replace the fan motor or relay as needed.
