I have a 2005 Kia Sorento. It's my understanding that timing belt must be changed around the 60,000 mile mark and I'm getting close. The price of the actual belt is under $100 but was quoted $900 to replace it. What gives? Do they have to pull the entire motor to replace on of these things? Does this cost sound correct to anyone??? I can almost replace an entire motor for that amount. If anyone can shed some light on this, I would be grateful! Thank You!
