Should there be quite a bit of coolant in the intake manifold 700 1987

"The engine is a B230K, manual, 150K miles, 2b5 pierburg carb."

Ah- this would be why you don't have an idle air valve. It's not
fuel injected!! If you're experiencing idle troubles, you'll
likely need to get a rebuild kit for that carb, and a fwe cans of
carburetor cleaner, and clean it up and get it back to spec.
The same troubles apply, as far as gunk on the throttle plate
and passages causing erratic operation and poor air metering.

As for removing the temp sensor, yes, sure you'll get a bunch
of coolant out of the hole- you just drained the water jacket of
the head! Make sure your level is OK after a couple of hot/cold
cycles with the engine.
