2009 Corolla water pump leaking coolant
I just went to get an oil change for my mom's car (2009 toyota corolla) and the technician told me the water pump was leaking coolant. He showed me how it looked (bad), and told me to get it fixed ASAP. They were going to charge $280, so I decided to come home first to get some second opinions.
First, will this be still covered under warranty? We bought the car new in June 2009 so it's still under 5 years since we got it.
Second, is $280 a complete ripoff (probably yes?). Is this a easy DIY fix? I am not a big DIYer but if it can save me a lot of money while not costing much time/effort, then I am willing to learn how to do it.
