I have a 99 GS300 with 49K on it, and it seems to be leaking a little bit of coolant. I took the car to get an oil change at the toyota dealer, and they are saying that it needs new water pump! I cant see the leaking on the water pump, but I do see a few drops after i drive, any suggestions? Could it be something else?

Thanks

 

maybe you can get some opinions from another outside mechanic?
