No biggie on the advice my friend,lol.
I think you're probably overthinking it a bit on the temp reading. The amount of energy and time it would take for the heat soak to get from those glow plugs, thru all of the head casting, into the coolant, and warm that much water up around the sensor would be tremendous. Really the plugs are on a timer, the length of that timer is controlled by relative engine temp read thru that sender, to glow according to ambient temp on a cold engine, or to provide a shorter glow on a hotter engine. It's just a close enough is good enough thing. I still have great starts every time with this setup.
It's really too bad that other engine got seized up, it looks about like a brand new engine, hardly any oxidation even......

With the sender in the other location, it will only read warmth if the engine has been up to operating temp recently. When engine cold, it would seem like it would never turn off the glow plugs, at least until a timing circuit cuts it off, if there is such a thing.
Am I overthinking??  |
