Hi all.

I found a way to install the aftermarket "Hastings" temp gauge sensor
into the coolant flange:

Not an optimum location, but it doesn't leak. I think that's as close
as it gets without drilling and tapping the head, or buying an inline
adapter that connects to the upper rad hose.

Gauge now says 100C. And rad fan came on when idling (though I had to
rev engine to get hotter coolant to move)

I think my new coolant pump isn't moving enough coolant. Local
offerings provided the pump with the stamped metal impellers. They
look rather small to me. Not the same size or design as the plastic
OEM.

One reason it was running hot was that I forgot to plug the CMP
harness back in! D-oh! Connected it, and took it for a run up the
mountain. Runs WAY better with the CMP plug connected!

I'm taking it to my mechanic to check the CMP hall sender and re
install the timing belt. He will also use his infrared gun on it. I
may still buy one for future use. With any luck, he will time it
accurately, and this will help engine temps.

Neil.
