High performance radiator condenser, designed for superior durability to meet original equipment specifications. AC Air condenser compatible with 2006 2007 2008 2009 Dodge Ram 2500 3500 4500 5500 L6 5.9L 6.7L Diesel. Made from Aircraft AA5052 grade aluminum for prolonged lifespanand with raw aluminum finish. The condenser works as a car radiator by dissipating out heat but also cooling the high-pressure refrigerant gas, so it forms into a high-pressure liquid, then gets streamed to the receiver-dryer until it continues to the expansion valve. Package Include: 1x Air Condenser.

No Fitting Instructions Supplied! Professional Installation is Highly Recommended! PLS double check OEM radiator core/overall size & inlet/outlet location before ordering. The air-conditioning condenser is located between the car's grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state. The liquid refrigerant flows to the evaporator inside the dashboard, where it cools the cabin. The condenser works as a car radiator by dissipating out heat but also cooling the high-pressure refrigerant gas, so it forms into a high-pressure liquid, then gets streamed to the receiver-dryer until it continues to the expansion valve. If you feel not cool enough, it might result from a clogged air-conditioning condenser or disabled cooling fan. A leak in the condenser will also result in a loss of refrigerant. How to Replace A/C Condenser: Step 1: Discharging and recovering the AC refrigerant. Step 2: Condenser removal and replacement. Step 3: Remove parts that are in the way of the condenser. Step 4: Take off the A/C lines that run to the condenser. Step 5: Take off the condenser. Step 6: Install a new condenser. Step 7: Install the A/C lines and replace the o-rings.
