When to change a water pump on a 2004 tsx acura?

You should consider changing the water pump on a 2004 Acura TSX if you notice signs of coolant leaks, overheating, or unusual noises coming from the engine. It's also recommended to replace the water pump when changing the timing belt, as they are often replaced together to prevent future issues. Regular maintenance intervals suggest checking the water pump around 100,000 miles, or as specified in the owner's manual. Always consult a professional mechanic if you're unsure about its condition.
