When changing a timing belt, it is recommended that the ________ also be replaced.

• A. front crankshaft seal
• B. water pump
• C. timing chain tensioner
• D. engine oil filter

Answer: (A)

When changing a timing belt, it is highly recommended to replace the front crankshaft seal as part of routine maintenance. The timing belt is a critical component that keeps the engine's camshaft and crankshaft in synchrony. Given the labor-intensive nature of replacing the timing belt, it is prudent to replace associated parts that may also exhibit wear or could potentially cause future issues. The front crankshaft seal can fail over time, leading to oil leaks. Since the timing belt service typically requires significant disassembly of the engine components in the front, replacing the crankshaft seal at that time can save future labor costs and prevent the inconvenience of having to revisit the same area of the engine shortly after the timing belt replacement. Other components like the water pump might also be commonly replaced during timing belt service due to their proximity and potential for failure. However, in this particular context, the focus is on the benefit of replacing the crankshaft seal to mitigate future risks of leaks.
