re. 4kq coolant light flashing

[Ben Swann]

[Hello all...

I noticed a little bit ago that the coolant light flashes in my 86 4kq upon
acceleration or cornering.  The engine doesn't seem to be overheating at all
and I've checked the coolant level and it's fine... I'm assuming that this
is a sensor problem.  Any experience here?  Is it the level sensor in the
bottom of the coolant overflow reservoir?  Can this be replaced separately
or do you have to buy the whole bottle?

Thanks again.

The sensors are characteristically picky, but it is telling you the coolant is on the low side.

Top it off.
