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

Plug and play. Works very good. Well made.

Fits a 2009 dodge ram great

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!

As advertised. Worked perfectly as a plug and play for a 2013 Ram 1500 5.7 Hemi to delete the mechanical fan and smaller AC only e-fan. Have superchips tuner on tow tune. Have stock 203f thermostat. Comes on at 210f and brings down to 190f in about 30 seconds. With max AC on, kicks in at around 205f and takes down to 190f before turning off. Appears to have increased mpgs a little bit after getting rid of partially stuck on mechanical fan. Been on the truck for 1 day so far...

fit perfect in my 2016 ram 1500 sport, after install noticed a crack on the housing but doesnt seem to affect the fan
