As part of my rebuilding the engine in my BJ8, I installed a fan on the =
outside of the radiator with a manual switch for now. In addition, I =
installed the =E2=80=9CShovel=E2=80=9D a baffle on the underside of the =
radiator to direct air into the engine compartment rather than going =
down under the engine. Early driving of short distances on highways and =
city streets without the fan indicates that the Shovel is a great =
improvement for driving without overheating. I can go along at 20-30 =
mph in light traffic and some stopping with no overheating. However, =
you still need a fan to keep the engine from overheating in the hot =
Florida Sun.
=20
On the other hand, I did not have an overheating problem driving in the =
Chicago and Suburbs when we lived there for over 30 years which is about =
the same climate as Toronto, more or less as long as I stayed away from =
traffic jams in the summer months. Southern Florida is hot all the time! =
Next I will re-core the radiator.

Stephen,
Before adding an electric fan, here are a few things to consider:
I have a 6 bladed fan that was a factory option. It has made a =
measurable difference on my car. Many of the usual suppliers offer it. =
Some of these repros. have a reputation for fatigue cracking with =
disastrous results. I have had mine for 8-10 years & I inspect it =
annually. No problem so far.
Do you have an original type thermostat that has a moving sleeve to =
block the bypass port when the t'stat reaches the operating temp? If =
not, you are loosing some of the radiator's efficiency.=20
Do you have the original air baffles installed?=20
Using coolant mix in the summer with 15-25% antifreeze will improve the =
heat transfer efficiency of your cooling system measurably when compared =
to a 50% or higher mix.=20
Some antifreeze is necessary for water pump lubrication. I drain the 50% =
solution into Jugs in the spring & put a 20% solution in. I save the 50% =
solution & reverse the process in the fall.=20
Have you considered having your radiator re-cored with a more efficient =
core?
Is your electric system capable of the increased load of the electric =
fan?
=20
Depending upon your definition of practical, I assumed it meant easy =
&/or inexpensive, there are more things that can be done to improve the =
cooling system efficiency.

I=E2=80=99m interested in what is the most practical way to install an =
electric fan.
I know some people opt to keep the original fan blades as well, and =
switch on the electric one when it=E2=80=99s really needed, and others =
go for a complete electric replacement with a thermostat.
=20
I haven=E2=80=99t put an electric fan in, and I=E2=80=99ve got away =
without it so far. But I really hate getting stuck in traffic in hot =
weather- doesn=E2=80=99t happen often but it can get pretty damn hot =
under those circumstances, and it would be nice to have one less thing =
to be concerned with when travelling.
The traffic around Toronto is so awful, no matter how strategic your =
timing is- you can still get stuck.
=20
Now that my car is put away for the winter, I=E2=80=99m thinking about =
possible future projects.
