[s-cars] Coolant Warning Light (Maybe MFTS?) issue still.....

[brian hoeft]

also check the sensor connection at the expansion tank, very simple there, ,
could also give a little shake after you remove the 3 screws and
listen/feel  confirm the little float moves.

as fot the MFTS.. that switch *harness* was badly corroded and very brittle
a few months ago, fortunately i had previously pulled a good one at a
salvage yard that I spliced in. At the least it might be prudent to check
the female pins tightness and invest in some De-Oxit to clean the terminals.
that spray saved my ass many times.
