Re: [DML] fan failure,I though this was strange

[Martin Gutkowski <webmaster@xxxx>]

I have had this problem on my (then) 5000 mile car. Here's the reason:

The cooling fan motors have a drain hole which is located at the shaft 
end of the casing. If you drive through some deepish water, it will 
collect at the back of the casing where the brushes are - it can't drain 
because the DeLorean's fan motors sit tilted backwards. My guess is that 
one or more of the brushes get siezed up in their springs (which hold 
them against the commutator) meaning that althought hte water will 
eventually dry out, the brushes will stop making contact to the 
commutator a while down the track. Tapping with a hammer will free them up.

To prevent this happening again, drill a small hole at the base of the 
rear of the casing

Best Wishes
