Thank, and anytime!
If you can fit a coupe or later sedan G35 dual fan housing I'd do that. (for costs sake and less manufacturing needed)
If you go to the dealership ask them for a price quote for the fan assembly and fan motors blades, etc... Make sure it has everything.
(this is the best setup as the fans won't sit on the radiator core)
This is providing you have space to install the efans with the fan assembly.
You will then need a fan controller.
I used part# 226204 From Advanced Auto Parts (Hayden Electronic Fan Controller).
How it works:
You have the following cables:
Red (Power, you get this from the battery)
Black (Ground, you can get it from the battery or from a nearby ground)
Yellow (Ignition On signal.. So the fans kick on when the car is on, or you can connect it to the red cable and have it on whenever the temperature reaches its target even with the car off this is how I have it)
Green (A/C On.. this is optional I cut the cable off)
Orange (Positive for fan #1)
Blue (Positive for fan #2)
(after I turn off the car if I was driving in the city the fans may stay on for 30 seconds max!)
The controller also comes with a push in probe in which you push in the probe in between the fins (careful not to injure the radiator when doing so)
The probe is essentially a thermometer.
This controller comes with a small selector which you rotate to find your desired temperature to engage the fans on.
The fans will turn off 20 degree's from when you turn them on.
So if they kick on at 190, they will turn off at 170.
If you cannot fit the fan assembly them it gets a bit more expensive. (not by much)
You will need to buy fans from Auto Zone or Advanced auto parts or wherever you can.
Measure the radiator core.
then find 2 fans (as large as possible) and follow their instructions. make sure you are pulling air into the hood and not pushing them out. (most efans are reversible, double check).
Part No. 226116
16 inch fan (for drivers side)
Part No. 226112
12 inch fan (for passenger side)
You will also need some crimps and a tool to cut, peel and crimp.
Advanced Auto parts has a complete fan assembly:
Part No. 75628
if you have a OEM radiator it should fit... again please confirm with some more research (measure it)
I can get this a lot cheaper.... Just not sure how much shipping would be.
Also you may want to follow this link I made a DIY on this:
G35 Sedan D.I.Y. Stainless Steel 16 Gauge Fan Shroud/Plate (E-FAN CONVERSION)
Ps, When controlling the temperature. I would suggest going to advanced auto, and asking them to bring out the OBD2 scanner. plug it into the obd port (by the parking brake)
and go to view data on the scanner (with the car on)... this will allow you to see the temperature with the scanner on a degree based level. otherwise you will be guessing where the fans are to engage.
I engage my fans 192 (on the scanner).
In actuality the fans are kicking on around 185-188 (at the radiator).
^^ some clips from the PM i sent so EVERY one can benefit from it.
