Jiggle Pin
to day i put a spoon thermostat in b/c mine was messed up when i took the old thermostat out the jiggle pin was missing, could this cause any harm to my motor being the jiggle pin is somewhere in my cooling system?
I don't know 100% but I think that if there was one to begin with, that it won't hurt anythink. It's probably settled at the bottom of the water pump housing if it's anywhere. I wouldn't worry about it.
