I have a leak under the water pump. Previously the engine overhand we had to replace the radiator.
The garage said that the head gasket was bad after they did a pressure test. Not sure if they noticed the leak. The car runs fine. No water in the oil. Leak under pump is minor. The level in radiator maintains level.

Hello,

There are few signs to look for in the event of a failed head gasket.
One of the most common signs is white smoke coming out of the tailpipe. Also, it can have white residue on the oil cap.

Take a look at this guide, it covers all the signs and tests that can be done:

Go through that and let me know what you find.

So, are you able to see where the leak is coming from? You want to make sure it is the water pump before replacement.
It is interesting that they did not mention the leak.
Keep in mind that on this vehicle the timing belt needs to be removed to replace the water pump.

Let me know if you have any questions.
Thank you.
