I have a 2005 Santa Fe 3.5L engine with 90k miles on it and I am shopping around to get the best price for replacement. In addition to the timing belt, what other components should be changed at the same time. One dealer reccomends changing the water pump, the other says no, the water pump should be good for 140k + miles. How about the Timing Belt Idler and Belt Tensioner?.....Thanks!

 

First, the timing belt shodul be replaces ay 60K miles, not 90k. And while the pump doesn't have to be changed at 90K but it's a good idea to do so because you are already in there. Better to replace now instead of later when it could die and leave you stranded. And yes, the tensioner and idler should be changed with the belt.
