Water pump started leaking and found out that it is driven by the timing chain.There is quite a bit of work to do this job.I have not fixed it yet.
My car started overheating quite frequently, luckily it was still under warranty so I took it to the shop and they told me it was the water pump. They replaced it and I still had to pay my deductible which wasn't cheap. I drove the car for a couple of months and it started overheating again, I checked the coolent tank and it was practically empty. I took it back to the shop and they said it was some kind of hose and the cap to my coolent overflow tank. They replaced both of those things and not even 2 days later it was overheating again. My dad looked at it and it was the water pump again, so I bought one on Amazon and my dad put it in for me. Since then I really haven't had anymore overheating problems.
