At 60K miles the warranty wants you to replace the timing belt. Some mechanics also recommend replacing the water pump. Is it necessary? The WP is covered by the warranty to 100K miles. Whats the repair history on the WPs?

2003 Hyundai Sonata Question: water pump replacement
Answer #1Bret Bodas from RepairPal Test Shop, September 30, 2009, 22:53Master
If you replace the water pump with the timing belt, you will be saving 2-3 hours of labor cost than if you were to have to replace the water pump by itself. So it is a kind of insurance policy against having to replace the water pump at a later time.
I don't have experience with Hyundai's, so I don't know how reliable they are.
How much is the extra cost for the water pump?
