Hey Everyone, My 2005 Chrysler 300 (60k miles) is leaking anti-freeze. I just noticed it today. It all started from my heat blowing out cold air last night. I Refilled the coolant and everything seemed to work fine... until today. I checked under the hood and saw that the coolant level was damn near gone and anti-freeze was on the floor pan. It looks as if there is a leak of some sort though it may be coming from the drivers side. I've been trying to trouble shoot the possibilities. Help anyone? Could it be the water pump?

Thanks Mario

There may be a leak in the heater core or with the heater control unit. This would account for the antifreeze leaking inside the car. Doesn't sound like the water pump at all. Be sure to only use a 50/50 mixture of Zerex G-05 antifreeze and distilled water. Otherwise, there can be unintended consequences.
