I have a 96 Pontiac Grand Am 6 cylinder 3.1 lt. The red engine coolant
waring light has come on, I added some 50/.50 Prestone Dexcool coolant mix
to the coolant surge tank to the engine cold level but the light stays on.
Does anybody know what the problem might be and how to fix it. Your prompt
replies will be appreciated.

Thank You

Number one: You have a leak that you will need to address.
I'd hazard a guess that you may have an intake gasket leaking if
you can't see any obvious external leak.

Number two: Tap the coolant overflow bottle right where the
level sensor is. Often, when the coolant level goes down enough
to turn on the light, the sensor gets a little bubble of air that keeps
it from returning to the "off" position when coolant is re-introduced
to the overflow bottle. Tapping the sensor area will usually fix
this.
