Installing an Electric Fan on the radiator using the snuggle method
This step includes installing an electric fan on the radiator. The fan is a 12" Derale Tornado fan that I purchased from Centreline - it's a perfect size. The larger engine pulley that was installed to take the extra belt for my AC compressor meant that the engine fan had to come out. At the moment I have not sourced a condenser but I will still need an electric fan in the car to prevent overheating until the time comes to install the condenser and unfortunately this will mean taking out the radiator again - it's actually quite easy (30 minutes) although the drain plug is tough to get to on my radiator.
Cileberti Motors had already changed over my engine pulley and installed the compressor brackets. I drained and removed the radiator and assessed the situation. I wanted the fan on the engine side to give more room for the condenser and its fan and so a bit of testing and fiddling was required before I learned that the electric fan had to be located on the left hand side of the radiator and that the shroud had to go. It is a very very tight fit and only just clears the pump assembly to which the engine fan was originally attached.
I sourced several generic brackets from the shelving section of my local hardware store (Bunnings) and I modified these slightly and used them to hold the electric fan. The vertical brackets on each side of the radiator were fitted to the bolts that previously held the shroud in place.
I painted these in black to make my installation look a little less like a cheap bookcase.
The advantage of using these brackets is that their impact on restricting air flow is minimal (notice how I have orientated these on the right hand side of the radiator) and they allow the electric fan to fit right up against the radiator. I call this installation the snuggle method
Holding the radiator in the upright position, there is a small amount of vertical play (amount 1-2mm) in the fan on the right hand side when using these thin and bendy brackets and so a little reinforcement of sorts may be required to prevent excessive rubbing on the radiator.
The finished product. Not bad if I don't say so myself and far superior to using plastic cable ties that might slice through my radiator fins.
