Solution
1. Preparation
  • Tools Required: OBD-II scanner, coolant tester, compression tester, socket set, torque wrench.
  • Safety Warnings: Ensure the engine is cool before beginning work. Disconnect the battery.
2. Compression Test
  1. Remove the spark plugs using a socket set.
  2. Insert the compression tester into the first cylinder.
  3. Crank the engine to take the compression reading; record the value.
  4. Repeat for all cylinders.
  5. Compare the readings. A significant deviation indicates a potential head gasket failure.
3. Replace Head Gasket (if necessary)
  1. Remove any components obstructing access to the cylinder head (intake manifold, exhaust manifold, etc.).
  2. Drain the engine coolant and oil.
  3. Remove the cylinder head bolts in the specified order using a torque wrench.
  4. Carefully lift the cylinder head off the engine block.
  5. Clean the mating surfaces of the cylinder head and block to remove old gasket material.
  6. Place a new head gasket onto the engine block.
  7. Reinstall the cylinder head and torque the bolts to the manufacturer’s specifications in the correct sequence.
  8. Reassemble all removed components and refill engine oil and coolant.
