Another awesome video. I find your channel and Alf’s Mustang Garage the most helpful on TH-cam. I love that you show your mistakes (learnings) and provide a running commentary on your thoughts as you are solving problems. Sometimes that’s just as helpful as seeing the step-by-step removal/install.
20:04 - Man, just this brief section of information on the wiring was more valuable to me than all the other videos covering this. Every video describes this process in terms of wiring schematics, which is great to establish a baseline of knowledge, but then it's in depth descriptions of the physical installation followed by "then wire it up..." You were the only person to describe *how* to wire to ignition, instead of just "wire it to ignition". Thanks a ton!
I had an electric fan on my 66. When it went out, I had trouble finding an electric fan that would fit well with the bigger radiator. Anyways, I went to a flex fan with the original fan shroud and haven't had any issues. I would consider trying to get some more space between the front pulley and the electric fan. Great video!!
Agreed, that space is tight. It has been a few weeks since I actually did this upgrade and I keep checking to see if anything is touching. Nothing so far. :)
When I did this to my 65 fastback I also changed to a Meziere electric water pump which made clearance a non issue ( and you pick up a little HP :-) . My rad was a 3 row champion like yours.
@@AndyKruseChannel They make a pump with heater hose provisions but it 's spendy!!! but they are SWEET mine went 10K with zero issues before I sold the car. Good luck Andy !
Technology is great On my 85 Corvette C4, I fitted two of these . As the fans have cages, I did away with the entire shroud. Allowing more of the aluminium multi core radiator to be seen. As you, I also wired it to turn on after a 10 second delay from key turn , always on. I used the radiator ties and also fitted a transmission cooler on the front 8 ties 😂🤣 Those fans great, on your car I'd have not used the shroud, fans too close to those bolt heads.
I think you're missing the point of the shroud, those cages you mentioned don't force all the flowing through the radiator to flow through the fan, that's why the shroud is needed. But, everybody has different ways of doing things. :)
@@AndyKruseChannel the rpm of the electric fan is many times more than the factory, also the aluminium multi cores already are 40% improved cooling. You don't need a shroud 😎 Just the risk of damage alone would see me remove it on this car, IMPO 👍
Andy - did I hear you right in that you hooked up this e-fan to start when the ignition comes on? So, at highway speeds and at any other speed, it would always be on? I guess it's much like the mechanical fan in that regard, but I thought your diagram showed that it would turn on/off based on the temp sending unit. Many of the folks I've read about with these fans have them only come on based on the temp sending unit but wasn't sure what you ended up doing. I live in Houston, TX, and I'm thinking it would just be better to have the dang fan on all the time as well. To do this, did you just omit the gray wire going to the temp sensor (Pin 86) altogether?
In this video, yes, the fan is on whenever the car is on (I didn't do it that way on my Fastback). The diagram I had shown was assuming someone would use a temp sensor for the ground (making it turn on and off based off the sensor limits) instead of just grounding the relay (which is what I did in this video). So if you want to skip a temp sensor, just put that wire straight to ground instead attaching it to a sensor. Now, with all that being said, when I went to put an electric fan in my Fastback, I chose to use the sensor. I chose this route as the fan is loud and I don't want to hear it any more than I need to. For your scenario, and if you were asking my advice, I'd say put that switch in. I have that convenient threaded port on my thermostat housing, so I didn't need to modify anything to make this sensor work. :)
@@AndyKruseChannel thanks for that info! I do have the threaded port as well on my thermostat housing, so I guess I could just use the sensor. Thanks Andy!
Tried an electric fan on my 68 Mustang but went back to the OEM as it cooled better. An option for you is to mount the electric fan on the front side of the rad, reverse the polarity and push the air through the rad.
When I was researching fans for this upgrade, there were fans that were designed to push and fans designed to pull. This one was advertised as a puller, so I don't thing I would want to do what you were recommending. Plus, the new shroud is designed to maximize the efficiency of the fan. So far so good. :)
Unfortunately I do not know as I sold the car not long after I made that video. But, for what it's worth, I plan to put a similar setup on my new project, the '66 Fastback. :)
Hi Andy, I have a question if you don't mind. I just installed this setup and the fan starts at the perfect temperature but doesn't turn off at the right temperature. I bought 200f to 185f sensor (for another car), and my fan turns on at 200f but stops working at 199f. So the off-temp doesn't work. I didn't install the circuit breaker, could that be the reason? I am confused.
I'm not sure which circuit breaker you are referring to, but I can't see why it would make a difference if your fans are shutting off at 199f. I suspect it's a faulty temp sensor that is triggering your fans, and those can be purchased on the cheap. On a side note, how positive are you that your temp gauge or temperature sending unit for the gauge is accurate? It's probably not the issue, but something to think about. :)
@@AndyKruseChannel Thank you for your quick response. I check on the dashboard the temperature, basically turns on and off at the same temperature. I am also guessing its fault sensor, apparently its common on these sensors to be faulty.
Awesome video as always Andy. At 7:49 I’m just wondering, did you have to go back and straighten out some of the cooling fins on the radiator? It looks like at that close quarters work might have chewed them up a bit? Always learn something when I watch - thanks so much! Just ordered a new Champion radiator for my 65 i6 - can’t wait to get it installed!
All the bent fins on that Rad were from me moving the shroud in and out to check fitment. The fan was more than an inch away from the fins when installed. :)
Hey maybe I missed it but how did you handle the temp guage wired to the temp switch and the new switch for the fans? Isn’t there only one port to thread into? They obviously can be wired into the same switch? Thanks.
On this car I wired it up so the fan is on when the car is on. Not ideal, but that was the limit of my patients at the time. Since then, I have installed a similar setup on my current Mustang and I have a temperature switch installed in the thermostat housing which activates the relay to turn on the fans. I could have done that same kind of setup on the car in this video (and I wish I did), but I chose a shorter path at that time.
Thanks for the info brother!!! I was literally just looking up these same fans on ebay and wanted to look on youtube. I should have plenty of room in my '71. How is everything so far ??
Hello. Can it blow air to the opposite side when the rotation direction is changed thanks to the fan blade structure? You mounted the fan inside the radiator. Can I place the same fan outside?
You can place the fan on the outside if it's a "Push" fan. It's not just the normal direction the blades spin, it's also the shape of the blades that dictate if it's Push or Pull style. The fan I installed in this video is a "Pull" style and it cannot be installed on the outside (front side) of the radiator and expect it to work just as good. When you find the fan you want, it should tell you somewhere in the details if it's a Push or Pull style. :)
I am actually installing an electric fan too. Here's my 2 cents: I don't recommend running the fan all time for a couple of reasons... Is your alternator like stock? Electric fans can draw 30 amps... Also you should had a fuse to that connection
If the thermostat fails, the fan won't run. This way the fan is not dependent on something else. Also, I don't run a stereo, so the amperage it would have drawn can go to the fan.
Honestly can't say I've heard of a radiator hose filter, but that doesn't mean it couldn't help. Thankfully there isn't much to be filter on the coolant side, other than maybe a old piece of rust breaking off from inside the block. Worst case it clogs a fin in the radiator or makes the thermostat stick open. I've never used one and I have no plans on installing one, but that doesn't mean yours is not helping. Sorry I'm not much help. :)
Unfortunately I sold the car before I got that far. I never had a problem with the fan and the pulley on the water pump touching from the time I installed it until I sold it, so it would have been lower on my list if I had kept the car. I'd like to do something similar on my new car, so we'll see how that plays out. :)
Electric Radiator Fan - 16", includes relay kit, purchased off ebay for $40 Radiator Shroud - Made to fit my Champion radiator. The radiator model number is AE259.
I did a video a while back where I pulled the heater box to replace the coil, but I didn't replace anything else. There might be some value in that video for removal and installation of the heater box, maybe it's worth a look? :)
It's nice to see a project that goes as planned. How is the cooling with this fan? Have you had a chance to sit in traffic with it? I would definitely hook up the thermostat especially if you have large temperature swings where you live. I'm surprised your car heats up that fast. Mine takes a good 5-10 minutes before it is at temperature.
Not yet, we don't really have traffic where I live (well not like the big cities). I haven't decided what to do about the temperature switch yet, there's good arguments on both sides.
I also did an electric fan conversion using a 16 inch thin SPAL fan... But I used a baking sheet to make the shroud 😂 😂 😂 it worked. I have video... But the fan was just too noisy for me. I ended up getting a 6 blade fan instead.
On the car in this video, never. I have sold the car since I made that video. However, it's been on my list for my new project. They're a little pricey, but I'd like to eventually upgrade to the electric pump. :)
Other options.. offset the radiator if needed.. also, reverse the motor on the fan, make it push air and mount it to the front..you will need to flip the blade also
my eBay electric fan was junk my 66 mustang would overheat sitting in my driveway ,,i found a regular old fan from a 77 tbird and now life is good and i dont need a shroud i hate ele. fans
Now you have 35 more useable horse power at the top end, because your not spinning that fan. P.S. use the switch and I had this Land Rover with a fan that close. Had to stop and patch it on the way home because the motor flexed the fan into the radiator 😡

Did you have to use nuts and lock washers for the pulley?
There are threads in the water pump shaft to hold the water pump pulley, so just bolts. :)
maybe as a push fan Infront of radiator, would of helped the engine run cool
Not as much as you'd think. :)

@@AndyKruseChannel so if that’s in the housing for the fans, where is the guage reading coming from? Thanks.
The gauge reading is still in the stock location, the port "above" cylinder five in the intake manifold. :)
Great video; thanks for sharing. Where did you source the generic fan shroud?
Thanks!
Found the shroud on Ebay.
Thanks for the info brother!!! I was literally just looking up these same fans on ebay and wanted to look on youtube. I should have plenty of room in my '71. How is everything so far ??

Why not before cutting go back to a thinner profile radiator?
I didn't have $300 for a new radiator. Cutting was free.
Did you ever cut a slot to move the radiator forward?
