Just replaced the radiator. Next day some water under the car. Fill it up again. A couple of days later some water under the car. Now, once ina while I hear a noise that sounds like its from the top of engine and today when the wife started it up I hear a high pitched sound that goes away when you give it some gas. I will have to see later if any more water leaks out. Does this sound like water pump issue? It was replaced about 75K ago so I thought it would be good for another 15K.

Lastly, if its the water pump, wouldn't it leak continuously or make the noise consistently?

Replacing the radiator would have no effect on the water pump, so there's no connection there. Should look for something directly related to the radiator exchange.

I completely agree but all connections are good. I just thought it was a coincidence especially since I hear a high pitched squeal every now and then.

Is it water or coolant? Water would be from the A/C. If it's coolant maybe your radiator wasn't the only leak. One of the small hoses might have a pin hole leak or it could be just leaking from the overflow after you turn the car off and the coolant returns to the tank. The squeal ya hear could be coolant getting on the belt and making it slip. Does it squeal with the A/C on or off? Personally I don't think it's the water pump b/c it would leak all the time. Let us know what ya find.

I appreciate the answer and didn't think about the belt making noise. Since 2+2 usually is 4 I thought that since its 80K miles since the pump was changed it would be that. You are right about the leak though. It seems to stop when I turn off the motor. The pump would continuously leak even when shut off, right? I don't see anything coming from the over flow. And its definely coolant.

This is a PS to the above answer to you. I pulled the plastic cover on the bottom off and you were right on. A leak in the lower radiator hose. Why? Because I'm a dummy. When I did the radiator I put the hose on reversed and it was slightly rubbing against the pulley and wore through. I just ordered the hose. A big THANK YOu to you!
