Cracks in cooling fins that do not extend into the cylinder head

should be left alone and monitored.
may be repaired by removing the affected area and contour filing within limits.
may be repaired by adding a stiffener.
require immediate replacement of the cylinder head.

The correct answer is: may be repaired by removing the affected area and contour filing within limits.

Cracks in cooling fins that do not extend into the cylinder head should be monitored and repaired if necessary. Option A is incorrect because although they do not require immediate replacement, it is still important to keep an eye on them and repair if they get worse. Option C is incorrect because adding a stiffener may not effectively repair the crack and could cause further damage. Option D is incorrect because it is not necessary to immediately replace the entire cylinder head for minor cracks in the cooling fins. Option B is the best choice because it acknowledges the need for repair while also providing a practical and effective solution.
