Dorman 621-410 Engine Cooling Fan Assembly Compatible with Select Dodge / Ram Models

This shroud was a great upgrade for my Dodge Ram 1500 5.7 Hemi.

The media could not be loaded. Plug and play!2017 Ram 1500 5.7L HEMI fits perfectly like from factory and I was able to delete my fan clutch and free up wear and tear on my water pump. I also kind of feel more throttle response?Overall great upgrade from the stock fan and fan clutch.The plug wires are a bit short but if you pull up on the harness and secure it with a zip tie, you won’t have to splice in longer cables.

Recibi el producto el jueves 14 de noviembre TODO PERFECTO, ya fue instalado y funcionamuy bien.NO entiendo porque dicen que aun no lo recibi o que intentaron entregarlo el dia 15 de Noviembre. Evidentemente estan equivocados. Yo ya lorecibi el 14 de Noviembre y la entrega fue satisfactoria igual que su condicion y funcionamiento.DEN EL PRODUCTO POR ENTREGADO Y CONFORME CON EL PRODUCTO DE DORMAN.ES EXCELENTE Y LO RECOMIENDO A TODOS LOS QUE TENGAN UNA RAM 1500 CON HEMI 5,7L V8.Ademas yo habia cambiado el termostato por el de 180°F que les compre a ustedes.Ambos cambios fueron excelentes para el funcionamiento de mi RAM 1500 2020 HEMI 5,7L Made in Mexico.

The media could not be loaded. Like others before me. I purchase to delete my clutch fan on my 2014 Ram 1500 5.7. Did extend wiring harness by just cutting some zip ties on the harness itself. So didn’t need to splice and extend. Haven’t had any issues and haven’t seen a need for a tune or 180 thermostat….Yet, but it’s also been cooler here lately. But figured since my a/c condenser fan went out. Might as well due this easy mod and it cleaned up the engine pay nicely. Time will tell how long this product will last but overall good buy for the money.Also on a side note fan was really well packaged. One thing I did notice is prior videos of unboxing it had cardboard protecting the tabs/sides of the fan. Mine had solid foam pieces so maybe they made a change to shipping due to tabs being broke off or damaged during shipping. Awesome job Dorman!

Got this to replace my mechanical fan on my 2016 Ram 1500 V8 to free up some horsepower. The harness WILL BE too short. So unless you find an extension adapter or you know how to splice in extra wire, then you won’t be able to connect the harness.

The Dodge Ram 1500 5.7L Hemi truck comes with an electric cooling fan for the a/c condenser and a mechanical clutched fan driven off of the water pump. My electric fan for the a/c cooler failed, leaving the cooling responsibilities to the mechanical-driven fan, which when living in Southeast Texas...isn't a good combination.I knew about the "clutched-fan to electric fan" mod that's very popular, and did a ton more research on the matter, and decided to make the mod. Basically, the mod is...the Ram 1500 V-6 truck uses the same radiator, but uses a single electric fan for all the cooling responsibilities. Since both the V6 and V8 engines use the same radiator, the fan mounts are identical too.I ordered this Dorman V-6 fan and pulled the mechanical fan and broken a/c fan out, and put the new Dorman fan directly in its place. The electrical plug is the one originally used for the a/c fan...same plug configuration, etc. It works beautifully!!! Before, my temp would climb to 217-219°F, and I would have to rev the engine while stopped, to keep the fan moving fast enough to keep from over-heating. Now, it doesn't go over 197°F!!Now, there are a couple of very important things to know before doing this mod. 1) Since the power comes from the a/c evaporator cooling fan circuit, it will only be energized when the a/c is turned on. So, you must leave the a/c powered on. 2) The exception to #1 is changing computer settings using a tuner, like the Diablo Predator 2 tuner (sold here on Amazon) to change the temp for when the fan will turn on.I have not needed to use a tuner...my a/c is powered on year-round. However, I probably will, at some point, purchase a tuner and make that change, while also making other mods to the truck's computer.There are plenty of YouTube videos that document the steps for this mod, and a novice can do it without too much effort or know-how. I'm happy with the mod and I'm very happy with my Dorman fan!!2022-08-30 update:The electric fan has operated flawlessly! I did use a Diablo i3 tuner to program the electric fan to be operational, independent of the a/c circuit. I have set the fan to turn on when coolant temperature reaches or exceeds 190°F. So now, I can turn the a/c compressor off, and the electric fan will still come on when needed. It's a beautiful thing!

Yes, this is the fan you want to replace that clutch fan on your 5.7 Hemi Ram. Unreal how fast this fan pulls the coolant temperature down.

Lasted 3 months, been making noise since I put it on finally went out. So I put original fan back on all is good now.
