My car is approaching 100,000 miles. Right now, it's overheating, leaking anti-freeze, making a noise and I was told I needed to (at the least) replace the water pump and thermostat. I need to know how much that might cost, and what else may be wrong.

did the local mechanic not give you a quote on what he said was needing replaced?the bearing in your water pump is most likely making that noise.also the leak you have is coming from the water pump weep hole.when a pump goes bad,the coolant will leak from that hole.that is what it's there for.change the thermostat also,the car is 9 years old.you may need a couple hoses if never changed.then you would need new coolant also.call around to local trusted repair shops in your area for quotes,or use the estimator at the top of this page.your vehicle info,your zip code,and work to be done.you may not like the estimator prices.if not, call around.
