Antifreeze is leaking on the passenger side floor under the carpet. The foam under the carpet absorbed the fluid but when squeezed it was a lot.

The reservoir was a little low and the radiator was full. I accidentally put water in the reservoir and it started leaking after that.

Hello thanks for using 2CarPros. sorry to hear of your situation. It sounds like the heater core inside the dashboard is leaking inside onto the carpets. Unfortunately the heater core is located inside the A/C housing under the dashboard. The whole dash board may have to come out to get to it. The heater core can not be repaired, it must be replaced.

Do you happen to know how much it would cost to replace the heater core?

Well the cost of the part isn't expensive, it's the labor to replace the heater core. It can be anywhere from $500.00 to $900.00 unfortunately. But call around to a few different shops and get an estimate. Hopefully you can find someone to do it cheaper. I know from the ones I've done, it hasn't been an easy job. But every car is a little bit different. Hope this helps some.
