The present beverage cooling apparatus has an insulated container with an inclined bottom wall shaped to fit on top of a wheel well in the engine compartment of a car. A series of coiled pipes inside the container can be connected to the car's air conditioner to pass refrigerant through the interior of the container to cool the drinking water or other beverage. A thermostatic expansion valve cools the refrigerant just before it enters the container. This valve is regulated by a temperature sensor which senses the temperature of the refrigerant as it leaves the container. The container has a capped drain opening at the bottom at its deeper end, a capped fill opening at the top, and a freeze plug on one side which detaches itself from the container if the beverage freezes. A motor-pump unit on top of the container has a beverage intake pipe extending down near the bottom of the container at its deeper end, and a filter is provided on this end of the intake pipe. The pump discharges the beverage to a dashboard-mounted dispensing valve through a T-fitting, a conduit with a U-bend, and a charcoal filter. The T-fitting has a small passage extending down into the container at the top. The U-bend in the conduit has a small bottom opening at its low point.
