Improve mileage 350 with Quadrajet

OK,
did some more research.

It seems my car stays cold?
it alwasys stays at the temperature shown in the picture. Just underneath 155F?

I already checked the thermostat. When the engine is cold, it is closed. I have no clue though at which temperature it opens. But after a little drive the coolent flows through the radiator, so the thermostat has opened.

I used a IR thermometer to check temperatures.

I measured 167F at the thermostat housing where the big hose connects.
and I measured about the same 165F at the top of the radiator where the big hose connects.

isnt 165F a bit cool for an engine to run and shouldnt the thermostat be closed?



Somebody I know is shipping me a fanclutch and cooling fan. I am gonna take the flexfan off and install a regular fan again. Because we drive our car all year, the flexfan is unnecessarily cooling the engine at low rpm during winter (cool) times.
