1993 Buick Park ave. " Coolant low" light on

Usually a normally open float switch in the overflow tank is stuck.

Try taping around where the sensor is in the overflow tank, sometimes
air bubbles trapped around the sensor fool it into thinking the coolant
is low. Make sure the bottle is at the right level too.

This is one reason why I'm glad I don't have a low coolant light, oil
change light, low tire pressure warning etc..faulty readings.

Good Luck.

Their is a coolant level sensor on the rad below the fill hole about half
way down the bottom of the rad, right side of the car. I replaced mine (on
a 91 park ave) about 2 years ago all it really needed was to be cleaned,
but I had to cut the side clips off the sensor to get it off. $23CDN at
the dealer, no local parts store carried it.

HTH,

Thanks for the info, I see it on the radiator like you said.  Think I
will wait a while before replacing it or messing with it.
