Solution

1. Preparation

Ensure the engine is cool.
Disconnect the negative battery terminal to avoid electrical shocks.
Gather necessary tools and parts.

2. Inspect and Replace Worn Components

Inspect Drive Belts:
- Remove the drive belt cover if applicable.
- Check for fraying, cracks, or glazing on the belt.
- If damaged, loosen the tensioner and remove the belt.
- Install a new belt by routing it around the pulleys according to the diagram.
Check for Electrical Shorts:
- Inspect wiring harnesses for exposed wires or signs of melting.
- Repair or replace any damaged wiring as necessary.

3. Address Overheating Issues

Inspect Cooling System:
- Check coolant levels in the reservoir and radiator.
- Look for leaks in hoses or the radiator.
- If low, top off with the appropriate coolant (Toyota Long Life Coolant recommended).
- Replace any leaking hoses or components.
Thermostat Replacement:
- Remove the thermostat housing and old thermostat.
- Install a new thermostat, ensuring the correct orientation.
- Refill the cooling system with coolant and bleed any air pockets.
