In this video, we're going to be working with our 2006 Chrysler 300 3.5-liter V6. We're going to show you how to remove and replace your engine's cooling fans for both the radiator and A/C condenser.

Here are the items you'll need for this repair: drain pan, antifreeze, side cutters, needle nose pliers, groove jaw pliers, flat head screwdriver, gloves, jack and jack stands

Raise and support your vehicle. We are using a lift to make it easier to show you what's going on, but this job can easily be done at home on a jack and jack stand. Open the petcock at the bottom passenger side of the radiator. Allow the coolant to drain into a proper receptacle. Once the coolant has finished draining, go ahead and close the petcock. You may still want to keep the drain bucket underneath there, just in case there are any little drips.

After draining the cooling system, remove the clips on your upper radiator hose. We'll do this using a pair of needle nose pliers. Simply compress this. Slide it out of the way. Wiggle the hose to release it and then move on to the clip on the radiator side. Once you've slid the clip back, remove the hose; place it off to the side.Push down on the tab and disconnect the fan clip. It helps to use a pair of side cutters underneath this tab to help lift it up evenly on both sides and pop it out.Remove the 10 millimeter bolts here just below the upper radiator hose fitting and one in the same place on the opposite side. We'll do this using a 10 millimeter socket and ratchet. Remove the cooling fans by leaning them back, lifting up and pulling them out of the vehicle.

Here we have our old part that we removed from our vehicle and our new part from As you can see, these parts are exactly the same. We have the same partition and two cooling fan assemblies. These fans rotate in the same direction. They have the same two bolt mounting location at the top as well as the same tabs at the bottom which we'll set into the hooks on our radiator.

Flip it over and check out the other side. We have the same two pin connectors for our wiring harness, along with all the same tabs to help secure it in place. Now your old fans may cease or have an open circuit inside of the fan which prevents it from rotating, which can cause the vehicle to overheat or it can cause your A/C to blow a little warm if it's not cooling the condenser, which part of this fan assembly does as well. If your vehicle is running hot or possibly your A/C is a little warmer than it should be, this new part from 1A Auto is going to go in direct fit, just like our original equipment, and fix you up right.

Remove the wiring harness. Lift up on the tab. Slide the connector off; unhook the wires from their retainers. Then install the harness in the same place and same locations as the old fan assembly. Now our fans are ready to be reinstalled in the vehicle. Install your fans hooking these latches into the hooks on the bottom of the radiator and lining up the top for the bolt holes. Reinstall the 10 millimeter bolts at each side. We'll start them by hand to ensure that they're aligned properly and then tighten them down with a 10 millimeter socket and ratchet. Reinstall the connector. Install your upper radiator hose. Once you have the radiator side installed, you can install the end on the lower intake manifold. Sometimes when the clamps are spread wide like this, it's easiest to do with a pair of groove job pliers.

Open the cap by pushing down and rotating it counterclockwise. Place a funnel in your reservoir and fill the vehicle with as much 50/50 mix of the appropriate coolant and water as the system will take.

Start the vehicle. Set the fan to the lowest setting and the heat to the highest setting. I like to set it to vent so it's easiest to feel through an open window. Make sure you have some extra coolant ready to go, next to the car, while it's running.

Continue to keep the coolant level up and monitor the temperature coming out of the vents as well as the one on the gauge. Once the vehicle has a steady flow of heat and has maintained it's normal operating temperature, the bubbles have stopped and it's stopped bringing down the coolant level, you can shut the vehicle off. Remove your funnel and reinstall your cap by pushing down and moving it two clicks. You're good to go.
