B says to replace the oil cooler

-A
-B
-Both
-Neither

Answer 1

Both option A and B have valid suggestions for addressing a spun rod bearing in an engine. Flushing the oil passages and replacing the oil cooler are recommended measures.

Step-by-step explanation:

When an engine spins a rod bearing, it typically causes damage to the engine's internal components. To address this issue, both options A and B suggest taking certain measures.

Option A suggests flushing the oil passages in the head and block. This involves removing any debris or contaminants that may have entered the passages due to the rod bearing failure. Flushing the passages helps ensure proper lubrication and prevents further damage.

Option B suggests replacing the oil cooler. The oil cooler is responsible for cooling down the engine oil, and if it is damaged or clogged, it may not adequately perform its function. Replacing the oil cooler ensures efficient cooling of the oil, which is important for the engine's overall health.

In summary, both options A and B contain valid suggestions for addressing the issue of a spun rod bearing. Flushing the oil passages in the head and block can help remove debris, while replacing the oil cooler can improve oil cooling and prevent future problems.
