Introduction

In this article, we will discuss the common overheating problems faced by Ford Fusion 2017 owners after a head gasket replacement. We will explore the reasons behind these issues and provide potential solutions. If you’ve recently replaced your head gasket and are experiencing overheating, this article will help you understand the possible causes and guide you towards a resolution.

Key Points

  1. Head Gasket Installation: The narrator, Efrain Gallego, mentions that he recently replaced the head gasket in his Ford Fusion 2017. However, he noticed that the car started overheating soon after driving it for approximately 10 miles.

  2. Cracks in the Cylinder: Upon investigation, Gallego discovered a crack between the cylinders that he missed during the initial cleaning process. This crack may cause the compression of water to leak, leading to overheating.

  3. Inspection and Diagnosis: To confirm the presence of a cracked cylinder, Gallego conducted a compression test using a test kit. He attached it to the reservoir or radiator cap and observed a change in color from blue to light green or yellow, indicating the presence of water.

  4. Leakage Source: To identify the specific leakage location, Gallego used a camera to inspect the piston without the spark plugs and injectors. He observed water dripping onto one of the pistons, suggesting that the cracked cylinder allowed water to enter.

  5. New Block Comparison: Gallego compared the new block he acquired with the original one and noticed a design difference. The new block had a hole instead of a crack between the cylinders. This modification may have been made by the manufacturer to address the cracking issue.

  6. Recommended Solution: Based on Gallego’s experience, it is advised to replace the old block if it has a crack between the cylinders. However, it is important to note that the new block may have a small hole instead. Proper installation and regular maintenance will help prevent similar overheating problems.

Step-by-Step Process

  1. Head Gasket Replacement: Follow the necessary steps to replace the head gasket in your Ford Fusion 2017. It is essential to clean the area thoroughly before installing the new gasket.

  2. Inspection: After head gasket replacement, observe the vehicle for any signs of overheating. If the car begins to overheat after driving a short distance, it indicates a potential issue.

  3. Compression Test: Perform a compression test using a suitable kit by connecting it to the reservoir or radiator cap. Observe any change in color, indicating the presence of water in the combustion chamber.

  4. Internal Inspection: Remove the head to inspect the gasket and cylinder walls with a camera. Look for signs of water leakage or cracks between the cylinders.

  5. Comparison: Compare the original block with a new one, focusing on the area between the cylinders. Note any design modifications made by the manufacturer to address the cracking issue.

  6. Block Replacement: If the old block has a crack between the cylinders, consider replacing it with a new block that has a hole instead. This modification may prevent future cracking and overheating.

  7. Proper Installation: When installing the head gasket, ensure it fits correctly and securely. Follow the manufacturer’s guidelines and torque specifications for proper installation.

  8. Regular Maintenance: To avoid future overheating problems, regularly check the coolant levels, inspect the engine for any leaks or cracks, and perform routine maintenance as recommended by Ford.

Conclusion

If you’ve experienced overheating issues in your Ford Fusion 2017 after a head gasket replacement, it is crucial to identify the root cause and find an appropriate solution. Efrain Gallego’s experience highlights the importance of a thorough inspection, proper installation, and understanding any design modifications made to address such issues. By following the steps outlined in this article, you can diagnose and resolve overheating problems effectively.
