I took my car in after the low coolant light came on. They said there was a leak in the radiator and reservoir. They replaced both. They got it all put back together. Now, they are saying it was a bad water pump. Do you think they misdiagnosed the problem and all along it was a water pump?

It's possible that you have a malfunctioning coolant level sensor. They often get clogged up, and/or fail.

If you paid for a radiator and surge tank, then they need to reimburse you as well as fix the water pump. Then you should never allow these people to work on your vehicle again.

If your coolant level sensor is working correctly, then something is causing your loss of fluid. A water pump can have a leaking seal around the pully, and/or the gasket.

The proper way to diagnose a leaking cooling system is to pressurize the system, then visually inspect the exterior of the motor, radiator, surge tank, heater core, and all of the hoses.

If you're loosing pressure, but the leak is not visible externally, then it is an internal leak. This would mean you have a blown head gasket and the coolant is leaking either into the oil, or going into the cylinder and out of the exhaust pipes.
