Check your water pump belt, to be sure its on and helps it circulate be sure it is full of coolant, and be sure your fans are coming on like they are supposed to as well. if all those are good check and possibly change your thermostat. did you charge your air recently and possibly overcharge *generating more heat than a normal fill*

94 cadillac deville...car will not start or turn over because the security light blinks on and off. had a new key made at the dealer and performed the relearn procedure..I put the key in the RUN position...


As the prescribed method isn't working it would seem likely the antitheft system is broken and should be checked by a professional.

Electronics aren't bulletproof and at over 20 years old the ones fitted to your car are 20 years less robust and 20 years less sophisticated and easily damaged by such things as welding, battery charging, jump starting or even nearby lightning strikes. Such instances often do not cause obvious damage immediately but rather have a weakening effect so the final breakdown happens later, maybe years later.

It sounds like they didn't get the cooling system filled completely, there's an air bubble. I had a problem with a 2000 Oldsmobile overheating, it turned out to be the aftermarket thermostat. I bought a stat from GM the problem went away.

have you tried to get your key looked at??
maybe the resistor on it is no good anymore,
or maybe the wires for this system are damaged,
they are two skinny white wires inside an orange sleeve
(that's how it is on my 97 deville)
check under the dash.

Overheating,eveything looks ok.


I have a 97 Cadillac Deville with a northstar engine and have replaced it twice so far, so i answer this by experience...i've noticed to my two prior engines that went bad that the normal temp should NOT EXCEED 228 (normal), the red overheating light will come on at 250 and at 260 it will beep and tell you to stop engine - idle engine and will begin to smoke (overheat).

I hope this helps you and anyone else...by the way if your asking why did i replace my engine twice is simply because my cadillac is super clean inside and out, immaculate condition.
