I recommend some heat shrink over all the spade lugs. Make sure they are all tight as well. Add some dielectric grease to minimize corrosion.

 

Hey folks,

Yea I definetly want a cleaner setup.

To the guy who asked about how it works:

The relay closest to the battery (left one) is on the fan closest to the top rad hose input, this fan is the thermostatically controlled one set to come on around 190F I can also manually override it and switch it on. The other relay is for the driver side fan and that is simply backup and in the summer will be switched on with the A/C One fan really cools down the rad quite a bit! I can always add a second thermostat if the need arises.

I also dielectric greased all connections! Heat shrink was an possibility but this wiring probably won't be a permanent setup, just until summer when I can take a while to really get some time to devise a really nice harness.

The hardest part of this project mod was mounting the fans, without a doubt. What a pain in the ****!!! I highly recommend if you are going to do this, if you can remove the radiator, it would make things a helluva lot easier.

EDIT: where would i wire in LED indicators?

 

Invest in some black ribbed cable sleeving and some heat shrink to make
it look like factory loom.

Mount the relays the correct way with the terminals below.
That keeps water out of the relay box.

Choose some colors to make ID easier.
Select the correct fuses and make sure your control circuit has a low amp fuse like 2.5 or 5amp rating as this does the switching only.
Higher rated fuse for the fans.

You can get a block sensor to screw into the water jacket just above the oil filter near the bell housing (Lightning) I think regular F150's have a front mounted filter.
This senses the correct temprature for fan operation.
(I had mine with the JDM fan kit but you can buy them separate)

If you where near me I would help any of you guys out with wiring
but there is a lot of water between us.

Good luck and all the best for 2008

FYI the JDM fan kit is one of the quickest and most tidy set up you will get.
Quiet in operation and reliable.
Just an idea. I think it will fit on regular F150's and HD's
Call Jim Jnr and ask him - he always seems to be the office chillin out. (Hi Jim)

 

JDM has some good stuff. There EFan included. The only thing I didn't like about it was that is has the factory shroud. So, you don't save any engine compartment room.

 

The shroud is the basis of a good kit as it allows the fan to draw air across the whole of the radiator core like the original fan, not just the area of the fan itself.

I have swapped out many fan kits people have installed that bolt through the rad core or just hang there on brackets.
Problem is if you get hot weather and a hot motor which has also been modfied and uprated you need to get air across the core to cool it down.
Many of these bolt through installation methods can work loose and damage the rad core resulting in leaks and loss of coolant.....

You can fabricate a nice sheet aluminium or stainless one which would look better agreed, however this kit just fits real neat and quick too.

Using the block mounted sensor is more reliable than one inserted into the core or feed hose.

 

Hey Ricki, do you have any tips for fabbing up one of the mounting shrouds out of metal sheeting? That would be something i'd like to do. I've seen people that have done it but no clue how they cut the perfect holes in them for the fans and whatnot.

 

it takes the right tools to make a job look professional.
it makes all the difference in the world
if you buy a sheet metal brake and sheer i'll be your best friend

 

I know what a metal break is and im assuming the sheer cuts perfect holes?

 

no it just give the metal that smoooooth cut . make a big difference in time spent dressing things up with a die grinder.

hole saw cuts holes

 

Ok got the wiring done correctly, shrunk wrapped and greased, mounted relays properly, etc etc. Did my headlight harness right as well...

Ricki remembers the wiring nightmare before....
