I was buying a car from someone and had it taken into Action to get checked out. They gave a list of issues along with 2 coolant leaks. One by the water pump and one by the radiator but said it's probably not the radiator and just a hose. I decide to buy the car and loose all my reserve coolant in a day. Take it into get an alignment and they say radiator is busted, take it to a radiator guy and he looks at it for one second and says the raditor is busted and there is no leak at the water pump.
Bottom line, I wouldn't trust these guys fixing my care, they would either misdiagnose or charge for extra work.
