I'm sure  somewhere there is a test to see if a thermistor is working or not 
before  installing it in a car. Probably something to do with resistance when 
it is  heated. I have three of them in the stash and want to do a simple bench 
check  before declaring them junk or OK to keep in the stash.

Anybody have a simple check with a multimeter and hair dryer  that I can use? 
Will a simple match produce enough heat to move a  meter?

Probably a heat gun would work. If not, how about a propane torch - lightly  
applied, of course. You could hold the thermistor in a vice (lightly) with the 
 sender end sticking out. That should give you a reading when heated. Lew 
Rishel  has a graph of the "resistance at temps" relationship. I know I have it 
here but  I cannot find it this moment. - Seth
