The old seized engine from China has two "probes" in the head.




The "new" engine in China only has one.



I'm guessing it has something to do with the glow plug system, as it goes to the relay.



I know one usually checks temp during glowing (right?). What would the other be? Where is the temperature guage probe, btw?
Thanks.
