Larry:
I still have the electric fan on, and after a few days of city driving in
the 95+ heat and 90%+ humidity, I have decided to keep it. The mechanical
temp guage never passes 210 (F) while driving.
I have the brand AutoZone sells, in the 12" model. The first time I
installed it, I had it as a pusher, but it covered too much radiator. I
moved the radiator forward 1/2", placing lug nuts from my 1977 Honda Civic
between the radiator and the diaphram. This gave me the clearance to mount
the fan as a puller if offset to the passenger side. No doubt, puller is
the way to go.
I also invested in the switch that mounts inside the top radiator house.
This is supplemented by a switch on the dash. Originally, I had decided to
go with only the dash switch, but prudence won. I could easily see myself
forgetting to pull it on and toasting a motor.
>From what I can tell (and it's not much), the fan seems to run nearly
constantly in city traffic. Of course, Hattiesburg is noted for its stop
lights spaced at car-length intervals. On the higway, it's anyone's guess.
I would think that at 70mph, enough air would be forced across the radiator
to keep it cool, but I don't know.
Finally, I put my auxillary radiator back on. It's a heater core from an 84
Buick that I mounted under the radiator pan. It's plumbed in place of the
standard heater, and provides marginal cooling. I really don't think the MG
was designed for the oppressive, earth-baking heat of Mississippi.
Of course, none of this is original, but then again, neither was my car when
I purchased it. YMMV.
