[DML] Re: Cool fan upgrades

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

It is not that the brushes are "bad", just worn out. Although you
*could* get the fans and the shroud out without removing the radiator
the better approach is to pull it all, replace the 25 year old
radiator, and rebuild the fan motors. It takes more than just brushes.
The commutator should be cut and polished and you have to do that in a
lathe (and maybe bearings?). The original radiator has plastic tanks
and if you look at the lower left-hand corner I would bet you it is
all green. Sign of leakage. That tank can blow off and leave you
stranded, I saw it happen a few years back during a traffic jam in
Providence. While you replace the radiator it is a good time to flush
the cooling system and replace the hoses. Now is the time of year to
do this kind of stuff so the car is ready and reliable for the
summertime. Half measures usually catch up with you. If you decide to
replace the fans you probably will have to eliminate the shroud. For
fans take a look at spalusa.com. You can find a fan that can move the
same or more air with less current draw. Lighter too.
