The origional otterstadt switch seems to go bad sometime before it is 
20 years old. If it is leaking, origional or the fans don't seem to 
come on soon enough it is time to change it. If installing a Fanzilla 
it is recommended it be changed at the same time. When installing a 
new otterstadt switch remove the seal, clean with a little 
scotch-brite and put the seal and switch in with NO SEALER. Make sure 
the clip is still there or at least use a strap-tie to hold the switch 
in. If you have an early set-up with the switch on top of the pipe 
modify the pipe and get the hoses to work like the later version so 
there is no air bubble trapped under the switch. 
If the switch is coated with crud you have much bigger problems since 
the crud is probably all throughout your cooling system. Drain, flush 
and refill with fresh anti-freeze if it is over 2 years old. If you 
have the origional hoses and seals you have a big job replacing them 
all including the water pump.
