what does it mean "1/4 pipe thread"?
I understand in standard international metric system. I remember all those stupid sizes in wrenches like 1/2 it's 12.54mm, 3/8 it's close to 10mm etc.
I'm not sure will I find it(sensor) tomorrow because I will walk to the junk yard and especially -- it's Saturday.
Also one more question about torque starter bolts - is it really just 16-18 lbs? I want to add blue thread locker - is it a good idea?

Mine was dripping from where the plastic meets the metal. I have had this type of unit fail on other cars as well.
On my 85 it failed when the metal corroded and the plastic blew out - what a mess....
