Common Causes

  1. Low Coolant Level

    • Symptoms: Temperature gauge reads high, coolant warning light on the dashboard.

  2. Coolant Leaks

    • Symptoms: Puddles of coolant under the vehicle, visible leaks around the radiator or hoses.

  3. Thermostat Failure

    • Symptoms: Fluctuating temperature gauge, engine temperature stays within the cold range or rises quickly.

  4. Water Pump Failure

    • Symptoms: Whining noise from the engine, leaks from the water pump area, overheating after short trips.

  5. Clogged Radiator

    • Symptoms: Engine overheats during idling, poor cabin heating performance.

  6. Faulty Cooling Fan

    • Symptoms: Overheating at low speeds or in traffic, fan not engaging.

  7. Head Gasket Failure

    • Symptoms: White smoke from the exhaust, milky oil, loss of coolant without visible leaks.
Repair Instructions

  1. Refilling Coolant

    • Ensure the engine is cool, open the coolant reservoir cap, and top off with the correct coolant.

  2. Repairing Leaks

    • Replace any damaged hoses or seals and repair or replace the radiator or water pump as necessary.
