I was quite gentle both removing the oil pressure sender and installing
the temp sensor, finger tight and then about 1/4 to 1/2 turn. Just
enough to snug it down.

OK, the location of the cylinder head temp sensor, I should be able to
see this while standing behind the van looking into the engine
compartment, not from under the van?

In my excuse for an attempt at my defense. :) Yep, I wondered at the big
difference in the wrench size of the parts, but the business end looked
the same and threaded by finger without a problem and the wire was the
same with the same connector, so I simply thought aftermarket
difference's, things change, try it and see, etc. If the business end
were not the same I never would have tried it.

Yes, it sounds like you exchanged your oil pressure sender for a
cylinder
head temperature sender.  I hope you kept the one you took out. ;)
Incidentally, if I remember right that pressure sender uses a tapered
pipe
thread.  Don't go crazy tightening it down; it needs to be just snug
enough that it won't leak and no tighter.

To find the temp sender, ook on the left cylinder head for a part that
looks just like the new one you bought, except dirtier.  It's in a
slightly hard spot to see, near one of the intake flanges.  It will be
inside the engine compartment, on part of the head that faces the side
of
the van.

A tip for future jobs:  Generally when you replace a part, the new one
should look very similar to the old one.  If it doesn't, someone better
be
able to give you a good explanation for why.
