Re: radiator fan stopped working

Mark,

I've had just about every cooling system problem that a Delorean could
have. First of all, put your fingers behind both radiator fans and
see if you can feel air coming out through either one. If just one of
them is working and one of them isn't then one of your radiator fans
has gone out (it's happened to me -- they're pretty expensive.)

If neither are working, then you can try this: The A/C switch is on a
wired-OR with the otterstat, so if you turn on the A/C and the
radiator fans come on, then you probably have a bad otterstat. You
can also take the two wires that go into the otterstat and short them
together. If both fans come on when the wires are connected directly,
then the problem is probably the otterstat. The otterstat is one of
the cheapest and easiest-to-replace components in the cooling system.
Of course, that just means (Murphy's Law) that it's probably the most
reliable. Mine, however, did go bad.

You might also have air in your cooling system. I used to get this a
lot until I got the "self-bleeder" add-on set. Try bleeding the
cooling system (see Service Bulletin ST-09-10/82, or check the DML
archives for instructions on how to do it) and see if that solves your
problem.
