DIY: How to mount a Spal Electric fan to the stock shroud

infinkc · Sat, Jul-19-2014, 09:38:11 PM

I searched and could not find exactly how people were attaching a Spal fan to their cars, so i took a few pictures while installing mine.

It cost $130 for the fan and relay, couldn't be happier.

I went with a Spal 30101516 model, its a 1610CFM with a low profile.

Sweet! Been looking for info how to wire one of these without having to install a bung into the radiator. Does it kick on like stock, just function more efficiently?

Well the stock one is clutch driven so the speed depends how hot the clutch is. 180 deg seems to be what's recommended by many for the fan to kick on. It will turn off if it drops 10deg also. Driving around today at 90deg out, it worked great. I thought it would be louder, but it's fairly quiet.

The main reason I swapped it out was to take the load off the water pump and also so I don't have to worry if a stock fan blade snaps and takes everything with it.

Any writeup on the wiring (what wires to tap or splice)

It's fairly simple so I didn't post all the details. It's just a standard relay.
12 from the battery jump post to terminal 30
Terminal 87 to the fan +
Terminal 85 to one side of the thermostat switch
Terminal 86 to 12v ignition( I used the red wire with white stripe)
Picture from FastM showing the wire used.

Since the fan wire was on top, it fits perfectly through the shroud as there is a square cutout.

You can always come seee and I can help ya.

Does anyone know the CFM of the stock fan?

(You need 2 brackets) Amazon.com: Spal 30130011 Fan Mounting Bracket (One Bracket): Automotive Amazon.com: Spal 30130011 Fan Mounting Bracket (One Bracket): Automotive Amazon.com: Spal 30130011 Fan Mounting Bracket (One Bracket): Automotive I used a Derale Fan relay harness 16738 180F Temperature switch. Amazon.com: Derale 16738 180 Degree Farenheit Single Stage Electric Fan Controller: Automotive Amazon.com: Derale 16738 180 Degree Farenheit Single Stage Electric Fan Controller: Automotive Amazon.com: Derale 16738 180 Degree Farenheit Single Stage Electric Fan Controller: Automotive I placed the fan inside the stock shroud with the wire on the top. You need to get (4) 1/4-20 x1/2" nuts and bolts to mount it to the shroud. just simply drill the holes and bolt down the fan. The fan comes with 4 brackets, so you do not need to purchase them separate. you need to cut the metal strap on the bracket down to the length i have in the picture. Install the bracket onto the fan and use 2 more nuts/bolts to secure it down. It will sit level in this position. The bracket can go on 2 different ways, install it so the bracket is closer to the stock shroud (lock nuts facing the front of the car) The fan thermostat you push into the radiator fins. i cut the probe down to about 1 1/2" so it would clear. I installed it next to the inlet. Once the plastic fan shroud is installed it presses on the sensor so it will not pop out. Here is a picture showing how much clearance the fan has to the water pump. I mounted the fan relay up near the firewall. the other relay there is for my AE's. I wired the relay slightly different than the instructions that come with it. I ran a 12v ignition to the relay(same wire i used for the AE's), then from the relay ran a wire to the temperature switch. The other side of the temperature switch i grounded.
