My Elantra will be coming up for the second timing belt change this year (120k). I did not own the vehicle at 60k so I do not know what all was replaced with the first T-belt change. I know that on some vehicles it is recommended to replace the water pump at the same time to save labor costs if it fails down the road. From what I understand, the water pumps on these cars are not known for failing and the pump is not driven by the timing belt. The pump is pretty easy to access and inexpensive. ($65 for OEM) I do plan on having new drive belts installed and probably a new tensioner. Is it worthwhile to replace the water pump as preventative maintenance or does that really only apply for cars when the pump is driven by the timing belt?
