ok..my add coolant light is on full time now.no matter what it wont go off.my overflow is full and its full at the filler neck. it used to just go off when i drove when it rained i.e. it would be fine till i drove over a puddle..kinda weird. the hose that came from the ast and went to the overflow was disconnected and i got that fixed.i ran the car while it was on jack stands and its not drippin any coolant.what should i do???as is replacing things?

you need to look at the wiring for the add coolant light



mike

i agree, probably something with the wiring

put electical tape over the light, and turn up the radio.....problem solved https://www.nopistons.com/forums/pub...IR#>/bigok.gif J/K

best idea yet

i took off the cap and there seemed to be a brownish buildup around the inside of the filler neck. also is there a website that corresponds with the wiring of it???

have you tried bleeding the system?maybe there is air in the line some where

I suggest you burp the hell out of it.

it's only 1 wire that completes a ground signal. unplug, if it still beeps, try grounding the wire to bare metal, if light goes away the you have a bad sensor, that is assumong the coolant IS full

u know fc's have this problem too
