DIY: retrofit 12'' slim fan in OEM radiator shroud... (for half size radiator)

Post by 4Door »

[FONT=Georgia]well, i have been running a Perma Cool 12'' slim fan for a long time now, i decided last night to make a new shroud for it, one that pulls air over the entire radiator and not just the center of it...

[/FONT]
[FONT=Georgia][/FONT]
[FONT=Georgia]
ITEM'S NEEDED:
1) old OEM radiator fan assembly
1) 12'' slim fan (other brands may work as well)
2 or 3) 3'' zippie ties
4) 8mm bolt's (hopfully you have the ones from the fan)
[/FONT]
[FONT=Arial Black][FONT=Georgia]6 to 10) 3/16'' rivets meant for plastic[/FONT][/FONT]
[FONT=Arial Black][FONT=Georgia]
TOOL'S NEEDED
[/FONT]
[/FONT][FONT=Arial Black][FONT=Georgia](preferred rather)[/FONT][/FONT][FONT=Arial Black][FONT=Georgia]:
1) 10mm wrench or socket
1) flat head screw driver
1) hand saw of some sort
1) die grinder
1) angle grinder
1) catch can of some sort that will fit under your car
1) wire strippers
1) soldering gun/station (wire crimper's)
2)
[/FONT]
[/FONT][FONT=Arial Black][FONT=Georgia]appropriate size [/FONT][/FONT][FONT=Arial Black][FONT=Georgia]shrink tubing (crimp connectors will work)
4) vise grip pliers
1) rivet gun
1) 12 volt source (i has a 12 volt converter)

TIME TO GET STARTED
place the OEM fan assembly on a work bench of some sort...

Image

with your hand saw, cut the finger's off, holding the fan to the shroud...
Image

this is what you will have left over...
Image

cut off the wire connector from the fan...
Image

now take a few minutes with your angle grinder and smooth down all of these lil raised portions, this will allow the slim fan to sit inside the OEM shroud...
Image

its kinda hard to see but both sides, all the way around, has been smoothed down...
Image

[FONT=Georgia]MOVING ON TO THE SLIM FAN [/FONT]

to prepare the slim fan, simply do the same as the shroud...
smooth down ALL of the raised portions on the out side diameter... these will not be needed as it will be held in place with rivet's...

fits like a glove
Image

Image

Image

now use your vise grip's to hold the slim fan in the shroud, this is so it wont bind up when your riveting the slim fan to the shroud
Image

[FONT=Georgia]time to attach the slim fan to the shroud[/FONT]

you can place the rivets how ever you feel comfortable with... i personally like to to use four at first, two apart from each other (basically, one on top, bottom and each side)
Image

before doing the wiring, i like to check the direction of the air...
because of how the slim fan sits inside the shroud YOU HAVE TO REVERSE THE WIRES...
meaning, red +, needs to hook to the negative side on the vehicles wire plug... if you hook it up red to blue black to black the fan will push the air instead of pulling the air threw the radiator... VERY IMPORTANT
Image

[FONT=Georgia]time for the wiring[/FONT]

i just cut the factory wire down to size and re-used it...
just strip approximately 1/2'' of the coating off each wire... [FONT=Georgia]AT THIS POINT, PUT THE SHRINK WRAP ON THE WIRES[/FONT] or you will have to re-solder them... now, twist the red and black wire together, then twist the blue and black wire together... next go ahead and solder the wires together, after your done, take your cutters and cut off the excess wire so your left with a straight piece of wire
Image

Image

Image

at this point, go ahead and install it... make sure to top off the radiator with antifreeze... bring it up to temp and make sure it not only turns on but it blowing the correct way... it should suck the air threw the radiator and give you more efficient cooling...

lol so whats the point of the slim fan if its no longer slim and the same width as oem?


i made a fan shroud awhile back, its square and covers entire radiator...and its only like 5/8" thick.

The stock motor and brackets for the fan is on the outside the shroud. So this is still about 2-3inchs thinner.

so it ad's 1.5'' to the height, the added cooling benefit makes it worth while...
why does it seem like your always negative..? i hear your a pretty cool guy but it's hard to see from your post's...

Good idea, but is it just me or does the fan seem backwards like the blades should pint to the radiator. Or is the lack of sleep kicking in and causeing me to trip.

how is it restricted oh wise one... the fan sits in the shroud to were the air is funneled in threw the whole radiator... you can see this in the first pic were it say's ''FITS LIKE A GLOVE" also, i put in the shroud like that because it fit perfectly, it moves way more air then it used to...

what does it matter how it sits... really, enlighten me...
no sarcasm meant, just lookin for your advise/opinion...
