I got a 96...on the dash right above where the tach needle spins a light came on...square box...with waves (which I'll assume represents some form of water) and an arrow at the top pointing down towards it...anyway this light came on...added some coolant wasn't really low...light no go off...hmmm...for ****s and giggles added washer fluid ...still no go off...so am I right to assume it's a coolant light...which makes me think it took a dump on me...so where the hell is this sensor and is it a PITA to change...I'm pretty lazy...keep that in mind... ...thanks...

 

If your full of coolant and hasn't gone off, the sensor may be bad. The sensor is that square bulky looking plug held in by a clip right below the radiator cap, facing the engine. picture

 

Thanks I woulda never found that on my own ...anybody know if that thing is hard to change...

EDIT: Cost prediction $100...

It easy to fix..Drive the car on ramps or jack it up. Drain the coolant a little bit enough to drain pass the sensor and then pop clip and replace. Fill the coolant level up of what little you drained and check your work.

 

Awesome thanks...
