My s2000 has been leaking water under the engine bay. I had a local mechanic take a look, and there was a bit of coolant leaking so they replaced the water pump. Now, I havent driven the car in a few days and its still been leaking puddles of water underneath the car. Is this normal for our cars?

 

If this is happening with the AC on then yes.

 

I havent driven the car in 3-4 days and it still leaks water

 

"water" or "coolant"?

 

If you're leaking pure water (and you used coolant in your cooling system), then it's going to be condensation from the AC system.

 

Is it possible to have consenstion even when the car hasnt been driven? Im sure its water, because it is clear and odorless. I live in socal and its been very hot/humid lately. Just a bit worried because it seems like way more water than ac condensation. It drips enough to flow past the rear of the car on a slight incline.

 

No, you can easily get that amount of air conditioning condensation on a humid day. Even more will leak on a humid day.
maybe it's in your windshield washer reservoir

 

I fear for the future of our society. Reading comprehension is pitiful. HE HASN'T DRIVEN THE CAR FOR DAYS AND STILL HAS A LEAK. So stop suggestion AC condensation.

Maybe when doing the water pump they topped up the overflow tank with plain water, and its the tank, or tank hose, that has been leaking all along.

At first leak was coolant, because tank was properly mixed, but now its clear because they filled the tank with plain water.

If this is it its double whammy for the shop. First they misdiagnosed the leak as wp, second they got lazy and filled the tank with plain water.

 

I have a really weird idea....get under the car and look.

It would be pretty funny if it was the windshield washer tank though, huh?

 

After bringing it home from the water pump replacement, it has been leaking without being driven correct?
Have you checked the coolant in the radiator and the overflow tank? Are they both at normal levels?
Have you checked the engine and hoses with a flashlight looking for slick/wet spots?
How much water would you say is puddling under the car each day?
Where would you estimate the water is dripping from (roughly)?
