my Toyota Camry Eighth Generation (2018-present) keeps overheating what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the engine is cool before starting any work.
• Disconnect the battery to prevent any electrical issues.

2. Coolant Level Check

• Sub-steps:
  1. Locate the coolant reservoir and radiator cap.
  2. Remove the cap from the coolant reservoir and inspect the fluid level; refill if necessary with a 50/50 mix of Toyota-approved coolant.
  3. If the radiator is low, remove the radiator cap and add coolant until full, ensuring to do this only when the engine is cool.

3. Inspect Cooling System Components

• Sub-steps:
  1. Visually inspect the radiator and hoses for signs of wear, cracks, or leaks.
  2. Check the radiator fan for any obstructions and ensure it spins freely.
  3. Remove any debris from the radiator fins to allow for proper airflow.

4. Thermostat Replacement (if faulty)

• Sub-steps:
  1. Drain the coolant from the system into a clean container.
  2. Remove the thermostat housing bolts using a socket set.
  3. Lift the thermostat out and replace it with a new one, ensuring it is oriented correctly.
  4. Reinstall the thermostat housing and torque bolts to manufacturer specifications (typically around 10-15 ft-lbs).
  5. Refill the cooling system with the appropriate coolant mixture.

5. Water Pump Inspection/Replacement (if needed)

• Sub-steps:
  1. If the water pump is found to be faulty, drain the coolant again.
  2. Remove the drive belt using a socket wrench to relieve tension on the tensioner.
  3. Disconnect the water pump from the engine block, taking note of bolt locations.
  4. Install the new water pump, ensuring to use a new gasket and torque bolts to specifications (usually around 18-25 ft-lbs).
  5. Reattach the drive belt and refill the cooling system.
