5 Professional Solutions to Engine Overheating

As a trusted supplier of professional automotive repair equipment, including transmission jacks, we understand that an overheating engine can halt any repair job. Diagnosing the root cause is key to a effective fix. Here are 5 common culprits behind high engine coolant temperature and how to address them.

1. Clogged or Restricted Cooling System

Problem: After the engine warms up, check the coolant return flow in the overflow tank. Restricted or blocked coolant circulation is a primary cause of overheating.

Solution: A thorough flush of the cooling system may be necessary to remove blockages and restore proper flow.

Pro Tip: Avoid unnecessary part replacements. Start with a system inspection to accurately identify the restriction point.

2. Impaired Heat Dissipation

Problem: Excessive dust and debris buildup between the condenser and radiator act as an insulator, drastically reducing their ability to release heat.

Solution: Use compressed air or a low-pressure water stream to clean the fins of both the radiator and condenser thoroughly.

Pro Tip: Make it a habit to visually inspect and clean these components regularly to maintain optimal heat dissipation performance.

3. Thermostat or Water Pump Failure

Problem: A significant temperature difference between the radiator's upper and lower hoses during warm-up often points to a faulty component.

Solution: Check if the thermostat is opening correctly. A water pump with a damaged impeller that has "slipped" on its shaft can also cause this issue, requiring replacement.

Pro Tip: The temperature difference between the upper and lower radiator hoses should not be excessive.

4. Incorrect Coolant Mixture or Quality

Problem: Using non-standard antifreeze or failing to replace it periodically can lead to premature scaling and clogging in the engine's water passages and radiator.

Solution: Replace coolant every two years with the OEM-recommended type. Always maintain the correct concentration.

Pro Tip: Using pure water in the cooling system, or an antifreeze concentration exceeding 60%, will lower the boiling point and reduce cooling efficiency, leading to overheating.

5. Excessive Load from A/C System

Problem: Several A/C-related issues can place an extra load on the engine, overwhelming the cooling system. These include: excessively high high-side pressure, overcharging of refrigerant or oil, failure of the variable displacement compressor, or a blockage in the A/C system.

Solution: A professional diagnosis of the A/C system is required to identify and rectify the specific issue.

Pro Tip: An overworked A/C system directly steals from the engine's cooling capacity. Don't overlook it when diagnosing overheating.
