[s-cars] After run coolant pump - when should it turn on ?

[Wayne Dohnal]

Joe,

I went through the same process and agony that you are.  I was convinced
that my temp sensor didn't work and the pump never came on.  Then a few
weeks ago on a fairly warm (but not really hot) day, I was out in the garage
a few minutes after parking the car, and I heard this noise.  After a few
seconds I realized it was the pump and fan.  This sounds stupid, but it made
me so happy to hear it running!  It ran for 30 seconds max, and it's not
very loud, so if I wasn't in the garage I never would have heard it.
